Old Boiler Room Emergency Repair (Worst job yet) 

Bro , I am a Pipefitter / Welder in the U.S., and all I have to say is that you have no reason to explain anything to anyone . No one is perfect in everything, and you have done the job professionally with all the corrosion and obstacles you faced . Great job and God bless .

I've been welding in refineries for over 20yrs. Shop welding and on the job welding are worlds apart. You made it work so youre good.

if ppl complain about your welds, they should start their own welding channel and show you, but like other said...if it aint leaking it is job well done. and from my point of view i think your stick welds look fine

This is my favourite type of work. Just getting it done.

Looks like you did a good job all around to me....thanks

I find metal putty works well on a worn flange. I look after the steam at a plant I contract to, and there are a few flanges here with Devcon metal putty faces that have been in service for 7 years. Planned to replace them but they never leaked, so they never worried about them. I love steam repairs. Love the video, and in this case, it's Saturday, so what ever gets the place going again for Monday.

I think your stick welds are fine, especially for the conditions you were working in. If they hold and don't leak, it's a proper job. As for a recommendation (after the fact 😮) I would have spent less money on a vehicle and more money on a proper mobile welder. Nothing beats a proper generator and a suitcase. Not functional in this situation? Then you did exactly what you needed to do and were successful in the repairs 👍

Really like your work. I think you’re doing great. I have been doing fabrication, welding/pipefitting and sheetmetal work for 33 years, all in the food processing industry. Because TIG is such a clean process we never stick anything. All our work is TIG. So, don’t worry if you are not a great stick welder. All your other work is excellent.

Lincoln low-HI’s 3.25 and 2.5 very forgiving rods, use a small Lincoln electric invertec. pops the odd fuse now and again but never cuts out due to a duty cycle. Dose stick and scratch start tig.

It don't leak anymore so it's a job well done in my book,we'll done Calvin keep going, stay safe

Calvin I seen your video about the old boiler room I got chills up my spine I really identify with you carry on brother

As a long term watcher of your channel, what interests me is your approach to the task and how you find efficient ways to get things done. It would be boring if you were a god level welder that never found anything challenging. I’m learning stuff from you that’s not necessarily about welding. You’re way younger than me, and doing something I don’t, but it is instructional and entertaining. Ignore comments that don’t contribute or please you, and keep doing what you’re doing. 👍

Absolutely nothing wrong with your stick welding m8 like you say can't be perfect at everything I do tig and mig and occasionally do stick welding if my stick welding was like yours I would be a happy man as long as it doesn't leak and does the job who cares what it looks like not like anyone is going to get up there and judge your welds top work as always

Repair Works what I do here in the US and I agree with everything you're saying you have to do as good a job as you can and make it work again I don't think some of these people understand fieldwork in shop worker are two different animals and I think you do amazing work

I repair boilers for a living and most boiler rooms are like that! Tip for the flanges, definitely clean the paint off the inside , shouldn’t get any problems then with cavities.

Always good stuff Arc one!. Ty for sharing. My only suggestion. Bring a rope with you brother. Tie your machine up, climb, then lift. Be safe out there guys.

Have consistently seen in previous videos that you are big on looking after your airways, so watch out for that insulation.... dangerous stuff in that condition and environment. Also, beware of unrealistic time pressure and remember you can always say no. I am an engineer and have seen some stuff. Removing the flexibility offered by that bellows might cause some funky stuff. The MMA welds looked visually ok. Some of those welds would/ should be pressure and/or RT in quite a few jurisdictions for steam service.

we use a miller xt305 with a tig attachment hooks up to the stickwelder stinger. then u just need yr bottle

I like your honesty. You are rare to be so honest, refreshing actually. As a pipe weldor, I found hospital boiler rooms to be my personal favorite jobs. Because then my efforts are for the good. People heal at a hospital. Over the years, I taught myself to weld with my left hand. Not everytime as pretty as my right. But a sound, ductile leak proof pipe joint I could do. Often...a 90 would be at a wall. I used my left hand (stick/tig) to seal that up. Often times from a ladder. Take tests either handed too. My last pipe welding job was in 2003, at a VA Hospital. All the best to you, your vids are a pleasure to watch, Thank You ! Pete 🙂

Those wrinkle belly’s look like the exhaust type. Lol. I’ll suggest that when you weld a spool to put the ground on the “fingers” bolt hole part of the flange especially with stick and scratch start. Cool job, great videos, awesome details. Thanks for the good advice in your videos

Yea hospital jobs are the best if you get hurt you don’t have far to go to get fixed up

Most people don’t get working on site is a total different world I did I know

Great content fella.

With the stick welding. You need to have a play with E7016 specials . They are very useful for pipe . There isn’t many videos on RU-vid on them . 2.5 mm will run as low as 50 amps . 4mm will run between 120 and 190 amps .

I’ve done loads of on-site welding with shitty little one phase sets best thing is probably turning the amps up a little higher than normal especially with the vodex and 6013 rods

Great video, I have repaired a few steam flanges that way, we spend most or our time at the same work in some rough boiler houses and tunnells,love the tip with the square for levelling the two hole on the flanges. You're stick welding is as good if not better than a lot of lads, real world conditions, keep up the good work, its not easy running your own business,👍👍👍

If the welds aint leaking you did a good job - You're a bit harsh on yaself with the arc welds - look fine to me.

Stick welds look bang on m8 👍🏻

For something like this I’d typically use a bohler 3.2mm special D 7016 set at about 110amp 6013 I tend to stuggle with slag inclusions , they’re great for tacking up but not so great for welding

CRUSHED IT DUDE!!!

Been there done that also have the same welder !

great video mate. when ive made mooring bollards for ships is usually run a 3.2 e6013 the the root on the pipe and cap it with iron power. not sure what they are exactly but ill find out at work tomorrow and get back to you.

Great video looks like it was a proper hard day there. Love how you can tackle anything 👍👍👍

Buy whatever tools you can afford to get most things done. You can also fabricate some shelves or tool storage system for the van. You will need a generator at some point or a welding genset trailer. I use cheap tools in my trade but I always have most of what I need.

Cool Video, Came out Nice 👍

the equipment you have is amazing and must have cost you tens of thousands of pounds. I hope the jobbing on the weekend makes it all worth it for you, but take your time off to rest your body & mind! Take care!

Não se preocupe com as pessoas reclamando que não é assim que se faz, só quem realmente trabalha com manutenção sabe como as coisas são... quem trabalha apenas na fabrica fazendo coisas novas não tem contato com clientes que querem diminuir todos os custos e não querem pagar para que a reforma correta seja feita!

Calvin remember value engendering

nice job man

you need a bigger machine, on site pipe welding itd be a 3 phase supply or no welding can be done on site that was a must before anything else can be spoken about, also had a esab caddy 251 the duty cycle is 100% at 150A so can run 3.2 rods all day long, we only used 3.2 upto 8 inch pipe though and yeah was also 6013 although we should of run 7018s and on site you cant always be the best welder your limited to the conditions your in its not like in a workshop the only lesson is just to learn how to manage situations to get the best out of them

As a car mechanic and handy man who does plumbing, electrical and welding I can say this great job. Everyone expects us to know everything and they know nothing. We deal with the crap we are given. What kind of Tig welder do you use?

This is what i do for work onsite welding, very different from fabrication in workshop, but it pays to have both skills. Lot of people dont enjoi it as lot of equipment is not good condition

A wise man once told me you don’t want to be the best welder you want to be the richest welder lol stuck with me that has 😂

we do the same like u in England east = Copenhagen mate!

With the tie-ins, just feather the start of the weld youre going to be tying into, dont need to grind it off after then👍 As far as the wanting to use 4mm rods goes, the only way of doing that, is to use a welder with a higher amperage range therefore duty cycle unfortunately. The way we do it (company i work for anyway) is with a Deisel genny, run cables out and then have a viper HF box hooked up to the cables. Can hook up your arc leads to that then, and gives you amperage control within short reach even if you're 100ft up on scaffolding (25ft tig torch too, after running argon hoses up from a bottle). Other than that, its simply multi-runs with 3.2's. Also, get your procedures and certs approved and switch to LowHy rods. Either 7016 or 7018 (a real good one is FilArc 56S). Wont get the slag traps then which any 6013s are a PITA for.

Shout me up if you're in north Herts, swing in the workshop and I can give you some 6013 pointers. Fantastic rod if you can treat them right, we weld pipe with them all the time to class 1 for gas rigs

Good job brother 🤙 🇦🇺

I don't understand the use of TIG instead of Stick - yes, you did explain why, but TIG is very sensitive to air flow whereas Stick welds anything anywhere under almost any condition. Also, boilers have Very Specific Weld Parameters that must be met to be certified in service and TIG may or may not have been one of the certified processes allowed. This is a comment only - not a rant (ok - a small one). You are also responsible for your welds (obviously) but they have to be up to code on coded pieces of equipment - Boilers are coded. PS - I did work in a Refinery, so have some background knowledge. 6010 Root pass with 7010 cover pass on coded vessels - normally. It isn't the Best Looking Weld but it has to be Up to Code Weld - that is the key part. Pretty isn't necessary, 100% welded properly is. You also need to get a better welder - you ARE doing critical welding and need to step your game up if you are going to continue doing critical welding. If you look at ANY welder doing construction, refinery, boiler, etc. welding you won't find them using the equipment you are using - for a very big reason. Please step up your game and get proper equipment and technique - you are responsible and if something happens to a piece of equipment that you welded - well.................. *** Here is an actual pipe welders channel: www.youtube.com/@arosswelding/videos *** Try him - you'll like him .

You can dc tig with that lunchbox welder i have a wp9fv forch for mine but go with a 17 my engine drive has a 26 series it would be nice to cary 1 set of consumables. Also welcome to mobile repairs you can buy all the tools in the world and you still won't have what you need when you need it.

3/32 rounds are normal to use for field welding pipe sch 40 to 80. 1/8 are rarely use unless the schedule is XX. Those little machines can only burn up to 1/8 6011 style and 3/32 6013 style.

You use whatever size rod your WPS says you should use... I'm a bit worried about that spool btw...not your work but it was there for thermal expansion. The axial load has now been moved somewhere else, hopefully other supprts were adjusted to compensate.

Your welds look ok to me ,a big thing with stick welding apart from the right voltage is arc distance ,the closer you keep the rod to the work the nicer the weld .Nothing is that easy when working on site instead of a,workshop 👍

If you are a rig welder you best get used to stick welding . That is all I could use following the procedures given to me

Calvin you took out a expansion joint and put in a spool was that ok with them

nice work brother 😁👍

Damn good job, don't let anyone tell you different & pretty good at stick welding for someone who hasn't done a lot of it, by the way how are those thermal arc machine's, not sure if there made anymore, keep up the great work 🦾🦾

Nothing wrong with your stick welds bro. Everyones a critic. We got a saying here in Canada. You're only as good as your last weld. They can all be perfect, and the moment you fuck up one or have a less than ideal looking weld, you're criticized for it.

As long as the welds are up to what code you have in the UK then no one should say shit. Saying that Boilermakers should be working on boilers, Pipefitters should be working on the piping coming off the boiler. Not sure which one you are lol. I just stumbled onto this video.

Whts the name of the respirator ur wear, looks a good job, great work keep er lit 💪

Hi, I've been watching you for a while now, Suscribed and following...I like your style. I'm Joe, sorry I haven't come across your name. I cut my teeth on stick welding where it seems to me you did the same with MIG, I should be having this conversation with you in a pub or on a site somewhere, lol..I'm 65 in May. Anyhow, got loads to chat to you about, was ex commercial diver, ,5 codings underwater, cut my teeth in the petrochemicals in Manchester then moved upto Scotland for the oil industry, loads to tell you. Anyhoo, Your stick welding is nothing to be embarrassed about and like you say, ..it's all about practice. I'll never forget the first time I tried a fillet underwater, then eventually it took me all over the world. I'd like to have a day with you..eventually. Best Regards, Joe in Manchester.

Я думал только в России проблемы с котельными. И у вас работы много😁

Was the service under 100 lbs PSI ? It would seem by the corrosion the customer would want for safety reasons to start replacing spools from flange to flange . Does the UK have a boiler code ? If so one would have to work under that code if the law stated such .As a rig welder in Canada one had to be aware of the boiler codes . We had to have liability insurance . The piping I usually worked on was high pressure piping . Weld procedures were used. Xrays and MPIs of welds were part of the integrity program

Stick welds look fine man who give a shit what anyone thinks get yours I usually do on slip on flanges is 1/8 6010 root clean it up grind any high spots off then run 7018 as hot pass fill and cap

Looks like you got the Fein MKAS 355 how does it perform? Do you like it? Looking for a drycutter and used Fein tools in the past. Thanks

What air unit you use not seen them as a backpack style.

👍👍

Who is the company that made those boilers? Interested if they are ones from the boiler company I work for Johnston boiler company

Be well carful of asbestos in those places .

What’s respiratory your using ?

How good is that optrel papr? Can u smell the fumes with the hepa filter?

Anybody know how/ why the UK favors 6013's for pipe?

nice work man

6011
