Excavator gp bucket material and its weldability

Today we will briefly talk about the material and weldability of the excavator gp bucket of the excavator.

1. The welding place must be cleaned up before welding.

It means to remove the original cracked weld meat and grind it with an interphase grinder or use a carbon arc gouging if possible, but the iron oxide must be polished after planing.

2. A certain preheating must be carried out before welding.

If possible, preheat 100 degrees at the welding position. Then use the 3.2J507 welding rod for welding, and the welding will stop after a while, hit the weld and the edge of the weld with a hammer, and keep hitting with a hammer until the weld is basically cooled. The purpose is to relieve welding stress, because it is impossible to do heat treatment after welding.

3. Appropriate welding materials must be selected when welding.

The electrode type is very important. If you want to know what material is, then you have to take some iron foam tests, which will come out after a test, and then distribute the welding rod according to the composition.

4. The welding of the excavator gp bucket body and the teeth of the excavator must ensure penetration

When welding, the penetration must be ensured. If the gap of the weld position is large, a back plate can be added inside.
