Hi there, I'm looking to get my aluminum GT frame repaired but can't find anyone who can TIG in the area. I have access to a MIG welder and have lots of experience with welding aluminum with MIG. My question is..... will MIG welding a frame be ok? Has anyone does this? Also, the frame is made of 6061 T6 aluminum. It is cracked in the heat affected area from an original weld, pictured below.
