Demolition Buckets Must Handle Severe Impact

After gouging out the old welds, we noticed cracks all the way down the sides.  The welder explained to me that he likes to pre-heat heavy sections before he starts the welding repair.

Preheating the steel slows the cooling rate in the weld area. This may be necessary to avoid cracking of the weld metal or heat affected zone. The need for preheat increases with steel thickness weld restraint, the carbon/alloy content of the steel, and the diffusible hydrogen of the weld metal.

The welder explained that it’s important to use a wire that will give you penetration and absorb severe impact. This is especially important for excavator buckets that are constantly taking a beating.

32 Mig Wire is mainly sold to our Heavy Construction Equipment Customers.
