ZX6R's are famous for weak footpedal brackets. After 10 years on mine I dropped it yesterday. Busted off the footpedal.
This must be high-magnesium aluminum and may also have some zinc. Just sputtered real bad and contaminated the tungsten. The tungsten formed a ball of crap behind the ball at the end.
Began to think it was Zamac, but it takes a lot of heat to get it to melt. I have done zamac with 4043 rods and it is not as bad if you get the filler in quick.
Camera batts dead so did not get before or the V-prep of the joints.
Hit jount with TIG. Arc just danced around and tungsten gets fouled. Had to keep replacing tungsten as after just a minute or so, it would not even arc. Finally managed to get a very dirty puddle, hit it with some filler and then managed to run a dirty bead. Then several passes of heat to boil out crap.
Lots of black everywhere. Funny thing, turn off torch and when you pull away you can see a red wave run across the unwelded surface as the mag burns.
Use 4043 filler to get a bead started and did basically a root pass. Finished with 5356 as that is probably closer to the parent metal.
Actually, I have brazing rods, they may have worked better.
Here's some picts:
Hmm, I just noticed the white ash all over. Must be some zinc too. No "stack of dimes" welds. but hopefully it will hold. Now just need to set up milling adapter on lathe to mill it square.
Frustrating, but I saved $90 for a new bracket.
