1. When we are about to weld, we need to polish the surface of the welding part by 2-3mm.

2. We should avoid the heating problem and keep hammering to eliminate the inner stress.

3. The bead weld process should be operated very fast with small lateral oscillation. We’d better adopt the minor diameter welding rod and the low welding current. The cooling speed must be high and we need to put the high manganese steel castings into water only with the bead weld part on the water surface for later welding. If necessary, we should also do heat treatment with quenching technology.

The jaw crusher has very wide range of applications in the industries of mining, metallurgy, building materials, railway and chemical engineering. It can break minerals and bulk materials with medium hardness and it has features of high operating frequency, low production cost and good economic returns. Based on our tips on how to repair jaw plates of the jaw crusher, customers will surely make more profit in the future.
