Welding Wire China  effect refers to the solder layer hardness, wear-resistant and heat-resistant properties, the performance level of the following factors:
1. Welding Rod  current size, the length of the arc. The current is large, the length of the arc, alloying elements easy burnout, Conversely, the beneficial alloying elements transition.
2. Preheat temperature, slow cooling conditions to determine the quality of the surfacing layer.
Some surfacing metal with different heat treatment methods can be different hardness.
Hardness and chemical composition of the surfacing layer refers to the surfacing metal surfacing of more than three.
