Welding 101

i also use a kempi tig....they are top shit. Good to see that atleast someone on here knows a little about pipe purging to protect the root peno from contamination.....not many people are aware of it and why its done...good work troy.

Welding whilst sitting on a good level bench is awesome for nice welds. Try welding pipe in the 5g position. My neck and back are killing after the root run and hot pass, let alone a few capping runs.

Michael,

Have you tried a product called "solar flux" ?? it seems widely used in the US as a paste flux purge to use on the inside of pipe welds where purging the entire pipe is either not viable or will waste a large amount fo gas ..

been trying to find it here in AUS but none of my welding suppliers have got it.

[r33_racer]

no i havent chris. haha i know the theory and prac behind purging....but ive never bothered myself, not unless i was making something and it was specifically required. The closest thing ive done when doing exhaust and i/c piping is stuff rags in the ends of the sections im welding to stop air running through the inside and contaminating my weld area. I suppose thats a basic form of purging if the gas was filling the section through any root gap i left.

[Craved]

yeah fair enough, i have the y adapters and stuff at home, but atm the cost of GAS overrides the need for true purging ...

all the exhaust work i have dont has been section cuts for wastegates - which i die grinded after each section was welded one.. making it smooth internally

[r33_racer]

if your good enough you dont get any real peno sticking through and dont need to grind it out For most piping on cars the strength isnt needed like it is in a structural job. If you can get it aligned spot on and dont get any peno it makes the job that little bit quicker and easier.

[Craved]

yeah your correct, but there is always that one spot that doesnt play nice .. then you get the small balls on ths inside from the penetration .. never very much though

haha, ye the 2g i aced but the 5g was a bitch.!

next time im bored im going to tig two cans together....they had one at tafe welded at the bases.

just thinking about doing that is hard lol

what filler would you use thats thin enough to melt before you blow a hole in the can?

[Adriano]

When i was at Meadowbank Tafe a few years back doing panelforming at night, there was a night mig/tig course.

[ylwgtr2]

welding at the base is easy...try the wall...it measures .1 thick

[r33_racer]

exactly the reason why i insist on the base...i would need a major stash of cans to get that one right and a butt load of time.

might be a noob question but anyway. I've seen electrodes for an arc welder that are suitable for stainless steel. Is it possible to weld stainless with an arc welder?

Anyone tried it if it is possible?

[femno]

yes you can weld ss with arc.

btw this thread is 18months old!

[Craved]

better to re-use this thread than make new ones, this SS ARC welding is with stainless rods? no point welding SS with mild steel

Yep your lookin for 316L electrodes or better, the rule of thumb is whatever material your welding always at least match or better it.

Best you just tig it much better in every way

[VB-]

not if you can't tig weld ^ or dont have a tig welder
