NOTE
1. Before welding, the electrode should be baked at about 350-400 ℃ for 1 hour. Weldments on the surface of the water, oil, chloride and other impurities must be cleaned
2. Aluminum bronze welding and carbon steel surfacing, thin pieces do not need to warm up, thick pieces need to preheat about 200 ℃
3. After welding with a flat hammer hammer weld, refine the grain, to eliminate stress, improve the strength and plastic weld.
