Re: Can this be welded back together?
AS a marine an specialty welding fabrcator: Yes. To be done properly the part needs to be removed and all the paint about 3/4" to each side, both sides need to be removed to bare shiny aluminum. Glass bead blasting works fine and should be washed with soap and water afterwards. The aluminum should be ground to 1/4" wide v almost all the way through. Leave enough material to realign the part with clamps. Preheat to about 400' F. TIG weld ONLY with 5356 filler only and NOT 4043 filler. you can do the prep work and the weldor should only charge a max figure of 25.00 to 50.00. Print these instructions out and watch your weldor dothe job..if they don't do as I have stipulated, TELL them do do it the way I have written here. Any other technique will fail and look like helll when it's welded.
