Practical tips to help move from running beads to making parts.
When I learned to TIG weld aluminum, moving from running bead on plate practice to actual joints felt like starting all over. Here are some basic, practical things you can do to succeed on these joints.

You can learn to weld. I'll show you exactly what to do in my affordable online welding courses at courses.timwelds.com.

Welder here, I primarily work with aluminum and SS using TIG. This is a great video! My 2 cents after training a good number of new welders is to really focus on the where the arc is pointing. On DC TIG its a bit more forgiving but on Aluminum with AC its not so much. I commonly see the top plate get melted back in almost a key hole fashion which means your tungsten is just a bit too high up assuming correct angle. This video does a great job of showing you how close your tungsten needs to be

I was just struggling through TIG fillet joints in the shop today. This could not have come at a better time. Thank you!!

@watchdogpedro Год назад

Just a really great job Tim, helped me greatly, got so good with Stainless but then doing ALUM was another learning curve.

@Scklate 11 месяцев назад

How does stainless compare to alu? I'm starting with alu due to a job I have but will have to do stainless soon.

@jeffreykiefer8839 2 года назад

You're right. It is like starting over. I have flat beads pretty much down. The filet weld is a hot mess.

@4speed3pedals 3 года назад

Good video, thanks. Speaking about the heat when holding the torch, go to the Weldmonger store and get the original and the XL TIG fingers from Jody.

@TimWelds 3 года назад

Great tip! I have several of them. They are great for shielding heat during welding, but I use mine a lot when I have to hold metal close to the tacking location. I also like how they slide over the metal. I also like to support Jody’s store because I really appreciate all that he has done for the welding community over the years.

@Eddy1_kenobi 3 года назад

Nice video! , I needed a refresher on aluminum t joints so this video was perfect!

@andrewlutton4684 2 года назад

Hi - my problem is starting the pool - my arc seems to change between on plate then another - when i watch you the arc stays lovely and focussed. Any suggestions greatly appreciated from a total beginner

@totallynotabot151 2 года назад

Struggling with the same thing - arc jumps between plates. I cheated by quickly jamming in some filler wire - not sure how much that affects penetration though.

@joe-cody8529 Год назад

The way your tungsten is shapend could have alot to do with that im not trying to act like im professional but i go to a welding school and im at a tig welding aluminim job welding pontoon boats but you want yoyr tungsten sharpend at a ball point and you want ti sharpen it with the grain of your tungsten

@strayedarticle2838 Год назад

@@joe-cody8529 I'm not a pro either, but I heard you don't have to ball tungsten on an inverter. That's just for transformers, or so I'm told.

@Yourmumstinksofpiss Год назад

@@strayedarticle2838 correct

@Trevorizsick 9 месяцев назад

Ive also found out a 60 degree taper on the tungsten also works if you dont like balling

@charlesday4667 6 месяцев назад

Love your videos! Very informative and well thought out!

@usaweld 3 года назад

Great Video Tim! Glad you are enjoying the Invertig 221 so far.

@TimWelds 3 года назад

Thanks! It runs as smooth as any machine I’ve used.

@brianpite0893 3 года назад

Great lesson! Thanks

@Scklate 11 месяцев назад

Very imformative. Thank you!

@split150 3 года назад

Great tips. I haven’t see the mention about increasing amperage many other places, so I’ve been messing with different technique and torch height thinking that must be the problem.

@TimWelds 3 года назад

Thanks! Torch height is the most important thing, but it’s really hard to flow the puddle without enough amperage.

@Hey_Its_That_Guy 3 года назад

Great tips Tim, thank you. Would love to see you explain the different types and sizes of MIG wire to use on various thicknesses of steel. What thought process do you use to determine wire type and size before starting a job.

@TimWelds 3 года назад

Thanks! I use .030 for almost everything. My most common thicknesses are 16g and 1/8” (3mm), which is ideal for this wire, but I can run it anywhere from 20g up to 1/4” (6mm). I do keep a spool of .035” on hand that I’ll load in if I’m welding more in the 3/16”-3/8” range. If you’re only doing auto body or thin sheet, .025 is an option. You can stretch the range quite a bit, so I prefer to just use a middle of the road option to keep it simple.

@foxtrot825 3 года назад

Great video, I'd love to see a cut and etch on those. I think my welds look good until I open them up and realize I totally favored one side or another. Keep up the great content!

@TimWelds 3 года назад

Thanks! It’s always a great idea to do a quick test to see how things are going.

@351kostakis 10 месяцев назад

Fantastic

@EarlPote 2 года назад

So youre setting the machine to 150 amps and mashing the pedal? I dont think you talked about what you were doing with the pedal while welding, unless i missed it.

@richardledesma1675 2 года назад

What frequency are you typically running on these welds?

@manny7360 3 года назад

One of the biggest problems I finally figured out was not having enough post flow. If there is not enough it fowls the tungsten and messes with everything. Seems like a no brainer now but it messed with me for a while before I figured it out.

@TimWelds 3 года назад

Great tip! It’s easy to overlook that on aluminum because it doesn’t discolor like steel and stainless, but it is definitely important to keep the electrode in good shape.

@chuckpeterson8586 Год назад

Your demos are good and your words accurate, My single wish for improvement is to use about half as many words. Thanks

@TimWelds Год назад

Thanks! I try to trim it down, but I always have room to improve.

@jimmywilson1388 Год назад

I can tell the difference when you’re talking about other types of welding processes…😂 You can tell you’re passionate about tig welding and I don’t blame you… I’m jealous, I wish I could weld like that.

@Justforfun-ek7et Год назад

I know this video is 2 years old, but I am wondering why you use the large aluminum plate (or I assume it’s an aluminum plate) to weld your aluminum coupons on?

@amcustomfab 3 года назад

Really enjoying your channel thanks for the good content. What camera do you use to get such great Arc shots?

@TimWelds 3 года назад

Thanks! I’ve seen a few of your videos, and you’re making some great stuff! I just use a canon DSLR (mine is an RP, but my T6i worked almost as well). I use an ND filter and manually mess with the focus, aperture and ISO. I’m sure there’s a more efficient way to do it, but that’s what I do. Keep up the great work!

@amcustomfab 3 года назад

Right back at you and thanks for the reply. 😎

hi i m on the curse and they teaching how to walk the cup on t joints what do u think a cant free hand it s hard for me because i can t rest my hand anywhere please help

@sloppydoggy9257 9 месяцев назад

I'm having problems with popping sounds when I'm doing AC on aluminum. I've tried cleaning the heck out of the material, but I think it has something to do with the filler material. It seems like it happens most often when I add filler, the tungsten doesn't look like it has aluminum on it, but its not a chrome ball either. Fairly certain I'm not touching the tungsten....

@Mike-lt6sj 8 месяцев назад

When you add filler in aluminum welding it will get sucked right into your electrode, and you'll get that pop. Some guys will pull away as they add filler, then run it down. Your torch angle also has a lot of influence there.

@cak752 3 года назад

Is the filler rod supposed to touch the tungsten or just the puddle?

@TimWelds 3 года назад

Just the puddle. If it touches the tungsten, you’ll need to stop and dress the electrode.

@L337KidKuso 3 года назад

I work at an aerospace company. Their fillet weld qualification tests have a ridiculous Min & Max height of anywhere from .042" to .120" on each leg of the fillet. Inspection is scrutinizing as all hell and God forbid you pass tolerance. And that's just aluminum...

@TimWelds 3 года назад

I know the exact test you’re referring to. I have so much respect for you guys who do that! Most of my career has been spent in aerospace engine manufacturing (as an engineer, not a welder) and I was inspired on a daily basis by the skill of the welders I worked with. My welding side hustle really helped me understand what a real challenge it is.

@lindsayweitzel4243 Год назад

This is an incredibly stupid question that I can’t seem to find an answer to… where do you place your ground for TIG welding? I’m assuming it’s clamped to the underside of your table?
