The tailgate latch on my 94 Mazda/Ranger pickup broke today..so as an experiment, I tried to tig weld the broken parts, not figuring it would work..but needing to try anyways. I figured it was pot metal as it appeared to weigh a bit more than an equivelent mass of aluminum.
So I set up for aluminum, and started buzzing away..and it melted and slumped about the time I could start to see a tiny bit of liquification. Blooosh. Shrug I did start low, with a 1/16" tungsten, and it went bloosh about 25 amps. The piece was about .250 thick, and about .375 wide, 1" long, placed on a piece of copper for a backing.
If Id had some zinc rod, I could have tig brazed it I suppose, but didnt and none was available in the area.
Any suggestions for the next time this sort of thing comes up? Besides a new latch from the dealer of course
