Gas welding

Thought about doing a gas weld today.....naa I filled an oil can, tightened up a loose 5' wood (!) ladder and installed a new power cable on a spare water cooled Tig torch that I had the new cable sitting there for 6 months. Then I ordered 25' of 1G welding cable for a new stick lead. I have a 20' length for the ground clamp. Are my stick welds going to come out uneven now?
Kidding aside, if and when I do it I'll own up with photos. Good thread about gas welding!

Anyone have experience fusion welding Chinese patch panels? I had a heck of a time, wondering if it had some kind of plating on it or if it was the quality of the steel itself….

Thanks,
Don

ask for an MTR (material test report) for what you bought

I wonder if they’re treated with something to make the trip over water?

They have an EDP coating that I sanded off but I think there may be some kind of plating. I’m going to strip the next panel more thoroughly and see how it goes.
 
i have a fender i got from ebay, so far no paint i tried yet will stay on it. i think its coated in some thing weird. its starting to rust now so maybe i could strip it down and try again.

I’m not even sure who to ask. It’s a $40 Chinesium patch panel of unknown origin.

Sadly--if someone cannot at least tell what the ASTM spec is or supposed to be--could be rejected carbon steel sheet that couldn't make some commercial use due to chemical or mechanical properties being out of spec. In that part of the world--they finish a lot of steel imported from neighboring countries to process. My guess is if it is really oxy-acetylene welding like crap--weird looking puddle, way too fluid, it's loaded with sulfur.

It seems to take a lot of heat to get a puddle. Looked granular? as it heated up.
 
i bought some new 1/4x 4x4 angle some years ago. big inclusion that didnt give any outward appearance. i had to throw away about two feet.
i cant imagine what a headache that would be in a body panel.

From that description--my guess is that the steel has a lot of what they call "tramp" elements in it like Cr, Vanadium, Mo, other that form carbides. The more of these--way more difficult to gas weld--more heat to get and nastier harsher puddle.

Thank you!

But I’ll need that $30k Baileigh power hammer! :D

Old Guys shaping metal by hand with hammers, a bag, a steel table and a handheld shrinker. And hard to argue with their results. The most valuable collector cars in the world were almost entirely built by hand. Ferrari, Lamborghini, Aston Martin, etc etc.


There are a lot of guys/Shops out there with expensive equipment that can't use it because they don't understand the fundamentals. Don't buy expensive tools like that until you can make complicated pieces by hand. (BTW I know you were speaking somewhat in jest:))
 
I can’t imagine how I could hand form this even if I wanted to. I know my limitations in time and talent… :). The patch panel cost $40…

When you can get a patch panel that is the way to go. With your patch above you could form it by hand but it would take some time (not as much as you think though) and experience. Peter Tomassini outlines how to make similar in his DVD's he offers.

If you can purchase a patch thought that is always the quickest, most economical for the customer. But you can't always get a patch for everything. :)

Or you could drop by Robert's Shop and have him form it with the Pullmax.:)
