Evening
A week before I tried to weld some kind of a timing chain cover that had a hole in it, needless to say I was over confident and it hit me pretty hard in the end - I failed badly as expected
At first it seemed to be an easy fix because the hole was neat with no cracks or whatever, cleaned it up nicely with ss brush & acetone, got a good puddle going and.. after cooling the bead cracked and almost snapped off. After a couple unsuccessful attempts part finally cracked on me.. Came in brave but left tottaly shot
Had no experience with any casts before, and a very little of welding alloy, luckily the cover was about to be replaced anyway if I had no luck.
Was using 4043 rod and what I found out, the weld was much much harder to grind with a tungsten tool than a parent material.
So...
My most common mistakes? -
Loads of preheat needed with a torch / etc. and try to keep it constant and cool down veeery slowly ?
Wrong rod?
Non weldable type of alloy?
Would brazing would work on alloy?
Thanks
