Welding Tips and Tricks

Hey,
I am an industrial welder who works in the aerospace industry, and only just started here a few months back. So I needed your opinion on TIG welding the dish of a piston. I work around qualified tig welders with high-quality specialized forgings made for the aerospace industry. We develop helicopter simulators for our contractors, and also we have a full-scale machine shop with standard CNC machines. I bought a set of SRP pistons, but then I noticed that it doesn't have any quench zones. I don't want to use them unless I have a quench zone in the dish. If that is the case, I should buy new flat-top forged pistons, or I will ruin my whole build.
What do you guys think?
Thanks!

Whoa missing a lot of info. Piston purpose? Combustion or just compression. Long stroke or short. Connecting rod wrist pin or straight throw shaft? Compressed material, fluid or gas ? Piston diameter? Connecting rod size or shaft size? Too many questions. What do you mean by quench zones?

If you need to add material to the existing piston to create your quench, then the base piston design doesn’t really matter. All that matters is conflict tolerance and using the appropriate filler for the piston material. I tend to peen the layers during build up whenever I’ve done tasks like this. Others may not feel it necessary.
