I am very new to welding, as in about 2 weeks. My question is i have some stainless exhaust to weld up for my car but im not up for butt welding exhaust pipes yet. Im going to take it to someone to have it done but it has to be tacked up while its on the car because its in pieces. So im wondering if using E71T-11 will be ok to tack the pipes together or is that going to mess up the final product? I am not worried about rust just that its not going to break.
