Welding Pin Holes In Sheet Metal

I ve done some gas welding with varing degrees of success.

Welding pin holes in sheet metal.

The most permanent repair to a hole in sheet metal is to weld the hole shut. Easy to do and really strong. I ve soldered all my life. I have no experience with mig other than reading various forums.

Immediately after applying the epoxy to the backer you can insert it in the hole and pull it up until it is tight with the original panel and slide the retainer clip over the pin until it touches the metal and firmly holds the backer in place. Make sure to use an electrode wire that is thinner as it uses lesser heat and prevents blowing holes on to the sheet metal. I ve read that works for welding shut drilled holes. My thought for the pin holes was to back them up with sheet copper will running a bead to help prevent blowing through.

Mix the epoxy and apply it to the front side of the backer and the center pin. Try going for a wire of 023 inches when welding sheet metal. Any kind of welder can be used but the best results come from a competent repairman using a tig or mig welding machine. Try welding with a scrap sheet metal piece and practice many times until you start working on more important projects.
