i am not the best but i did enough to say that what you did is good enough. i have around 100hrs with tig welding. i know you can be better if you can get some critical advices. you need to move alittle faster with the torch or modulate the pedal alittle to keep the weld from being too hot. if you overheat stainless steel, it will look black because it forms carbide precipitation. you need to back purge the pipe to prevent crusty bumps from forming inside the pipe when trying to have complete penetration with the weld.
try not to bevel the pipes too much because you will not be able to file in the groove formed by the bevels on the first pass.
on steel intercooler pipes, try to cut the pipe clean and just melt it together with the torch because it will be so much cleaner looking. use a circular movement with the torch. you have to use really skiny filler rods if you want to fill the gap.
get a gas len from the welding supply store. it has better gas shielding than a standard gas cup. it will make your weld looks cleaner. it is cheap too. around 3 bux. just break down your old torch and replace it with new gas len.
you work too far out for me to stop by. you guys need to move back to marietta. come by with a tank of argon, a box of krispy kreme donut, and i will give you a quick lesson. guarentee to be 10x better after one hour. if i come out there you have to ask drew to give me some dyno time.
go to ka24.org and check out the works done by other guys on there. some of them are amazing. it is in the welding section.
