I have 4 Maybe 5 Excavator buckets to weld up, One needs a few cracks fixed and the rest need new cutting edges. What i was hoping to find out is when i go to weld the new Edges on do i have to Preheat at all? the Cutting edges are 3/4" to 1" Thick and i beleave they are AR400. Will post Pictures as i Make Progress. Thanks, Reid
Yes give it a good preheat and use a low hydrogen welding consumable.
