While in the Navy (mid 70's) I was tasked with climbing up an aluminum mast straight up about 100' from the waterline to weld this bracket for a sensor, the only way it could be done was via stick, I never really cared for height but that trip broke me of that fear, I don't remember what rod it was, it was given to us by the shipyard along with instructions on how to use it, I had a can of the stuff to practice with and they inspected my weld at the NDT shop to make sure I knew what i was doing . The surfaces had to be super clean that much I remember. I wish I knew what rod it was because that stuff was awesome and put down a great bead, the welds were a flat fill and a overhead, the overhead was a bitch.
on the Aluminum rods (1300 and 4043) in addition to preheat, it is necessary to clean the aluminum first and then allow it to cool completely before removing the flux. Also, the rod burns back into the flux on the rod so you really don't see the arc. Both of these rods are difficult to use but they do have their uses, primarily on repairs where MIG or TIG cannot be done.
never used one (basically impossible to get over here so why search?) but everything you say is basically self explanatory. highly reactive metal, needs good shielding, sucks the heat away so needs heaps of current and preheat, and yeah... let the slag cool. and would only be of any use out in the middle of a paddock on a windy day when something just has to get stuck together and do the job. wouldnt want to try an intercooler with one, but to stick a pipe together on a irrigation pivot? sure...
@@paradiselost9946 The heat input on a 3/32" diameter rod is quite high so it really can't be use on thin parts or small welds. My experience with it has been with repairing aluminum irrigation pipes in the field and for structural aluminum welding where TIG or MIG is not possible. The thinnest material that I have used this on is 1/8" thick. You might try searching online for some of the 4043 rod. One of the interesting aspects of using this rod is the high consumption rate of the rod. It can produce good welds in the hands of someone experienced with it.
@@paulkurilecz4209 yep. exactly. irrigation pipes... or that farm implement that just broke... any rod works well in the hands of someone with half a brain and an ability to think and watch what theyre doing... sadly rare traits nowadays. nah, i once had a look from curiosity, rods are cheap enough but the shipping is the killer, so i left my curiosity at that... be glad youre in the US (i assume) where it seems everything is available?
I weld with 11018 regularly on excavator booms and buckets, way stronger then 7018. It welds the same as 7018 and in all positions, little trickier with overhead and vertical, but nothing major
Super Noob question: ive been doing a little spot welding for repairs on my mower. Usually i turn the welder off to change the stick. is it OK to change the stick (with gloves) while the welder is on?
@Granamire that's what I'm saying. Try horizontal. You won't have a good time. And for that matter, try it overhead as well. Sometimes instructors will challenge students with difficult and impossible tasks as a learning exercise. It's not completely impossible just extremely difficult and impractical. Take welding metal core(mig) overhead for example. It's not designed for it, and it's rather difficult, but I used to have to do it occasionally.(not saying you ever would weld jet rod overhead on the job)
What happened to this channel. It is now like a cheap infomercial. Bring back the older guys who actually showed you something valuable. This new s**t is aggravating.
You didn’t get any information outta this? The idea was to provide information on dozens of different electrodes. We hear yah. While the delivery is absolutely a joke. The information is accurate.
We are trying to put a new spin on presenting the information about things kids tend to tune out. We plan on doing more of the old school videos as well but are trying some other styles of stuff as well to see if it’s a fit. Thanks for your feedback
The hardest rod I ever welded with was inconel.Soon as it gets hot it work hardens instantly.Then it is invincible to anything.Don’t try to drill it.Had to use plasma to even touch it . EXPENSIVE to I guess according to my boss. Is really used for extreme heat conditions . Supposedly it is used on the space shuttle. Once in a lifetime opportunity.Most people will never weld it. It was a bitch to weld though.
