Q. WHAT IS THE BEST FILLER METAL FOR TIG WELDING ON LOW CARBON DOM TUBING? (Submitted by: CLINT DOSSER from JACKSONVILLE TX)
A. There are many good fillers for this material. It will somewhat depend on
the application you are using it for. For roll bar tubing I recommend a ER70S-6 filler. It gives good elongation and good strength. An ER80S-D2 filler is another good choice for a little more rigid applications. If you are going for looks only and elongation is not a factor, a 312 filler at the right heat input gives nice puddle color. Good luck and have fun.
