Hey fellas,
I find below two videos are pretty handy to get some idea about how to stick weld stainless steel & aluminium.
I'm guessing any of you welding aficionados might find them pretty useful and entertaining.

Bloody net is so slow tonight the pages won't load , never used a stick welder to do aluminium just Tig and Mig but stainless all three .
Still cracks me up when exhaust shops weld stainless exhausts with plain mig wire .
Yeah, I reckon that's not a good idea 'cos the welds will rust. An outcome you don't need on a stainless steel exhaust. :)Quote:

Besides, those rods cost an arm and a leg and a kidney. Can't afford to muck around with them. :D
I know that they are not widely used , I have never through all my years teaching welding seen aluminium stick welding in any of the text books .
Need to come and see you sometime mate. I've had no idea you teach welding. :)Quote:

But that's fading .
TIG is still my favourite domain. I'm no stranger to pain meds. Got shoulder, elbow, knee, neck & lower back injuries and multiple surgeries.Quote:

One thing you don't wanna do is to mix pain meds with sleep meds.:)
You can go to a calm happy sleep for days, and never wake up.(add alcohol do that and we are in serious trouble).
No doc or chemist knows how they interact inside our bodies, 'cos we all reacts differently. I learnt it the hard way. :)
Keep welding mate. It's therapeutic. Nothing's more fun than making something out of scraps that lie in the backyard or the shed. :D

Yeah they reckon you shouldn't mix that stuff with alcohol but I reckon it's grouse .
Only on one tablet these days Clonazepam.
What metals do you weld with TIG and what electrodes have you used , be careful with the Thoriated (red tip) ones , when grinding them make sure you have a dust mask or forced ventilation helmet .
I'm a newbie to TIG but I know it's my favourite. :)Quote:

Also thanx for tip about dust mask. I guess it's paramount to follow those safety protocols to make sure we don't get cancer in no time. While focusing to make sure I take care of my eyes from radiation, I completely forgot about the carcinogenic dust we inhale from welding.
Just mild steel and for the time being, 'cos I'm waiting for my AC/DC machine to start ally welding.
I need to learn to do ally welding pretty well, pretty fast, 'cos my upcoming hobby ideas will demand it. :)
I have heaps of hobby ideas to make out of scraps. Exercise equipment(some new ideas, some old ideas revived to be new, etc), push bike trailer, motorbike trailer, and mod my old rusty trailer into something weird looking, etc etc. :D
I also wanna make a tandem trailer from scratch, but don't have room.
I am onto making a bike trailer, which I need sometime soon. :)
Cheers
Yeah, that's ok. It's the pain meds we need to go easy with 'cos some of them mess with kidneys and liver, and obviously the brain as well, sinceQuote:

Hi I agree, welding is therapeutic. I think it's beause with the helmet on and the tinted lense you can shut out everything and the only thing you see is this magical dancing weld pool that you command.
I mainly use MIG and oxy, played a bit with TIG, but for the life of me I just can't do stick. I think it's because I'm an electrician and the arc from stick is too similar to the arc from electrical faults.
I finally found a use for the free gasless MIG wire I got with my welder. I connect my air compressor to the welder, wack the current up and use it for cutting.

Sorta like a poor mans plasma cutter , very clever , used to use 5mm rods on the highest amps an old machine could handle to put holes in railway iron for fencing wire .Quote:

Reason for caution using the red tipped ones is the thorium being a radioactive element , electrodes for Tig are not the same as electrodes for arc they are classed as not consumable , which is partly true .Quote:

The hardest material to weld is Aluminium if it's not meticulously clean and I mean clean , aluminium oxides almost instantly with a thin film covering and it's this thin film that stops a weld pool from forming , if this happens you apply more heat but you're more than likely to just melt a big hole before you get the weld pool you're after .
Never use a normal wire brush on aluminium, brass or stainless wire brush , clean area to be welded with a non metalic scouring pad and acetone but only clean as much as you can weld .
Only problem with using acetone is when you're welding bright metals like stainless and aluminium but in particular stainless is the reaction of the gasses formed while welding you can't see them but there there and nasty .
Which is why they invented the welding helmet with forced ventilation I believe , the gases mostly are very close to the area being welded and just out of reach for you to breath in under normal circumstances.
Hint here is if you can smell any petroleum product in the area your welding which includes turps based paint try and remove the source of the smell .
You have certainly picked a few big jobs to tackle there mate , if you need advice I'll help where I can if you need a brush up on skills etc I will see what we can do , not sure how far away you are .
Thanx for that tip. It has never crossed my mind it can be used as a cutter.Quote:

The compressed air helps to expel the weld metal and keep the gun and surrounding metal cool.Quote:

Where are you heading to?Quote:

Cool mate. Enjoy the trek. Cheers.Quote:
