堆焊可用于修复局部损坏及磨损程度较大的锻模,堆焊后硬度达HRC45以上。喷焊可以用在磨损量较小(1～3毫米)的模具上,也可以用来强化新制造的模具。电火花强化技术可用来强化冷作模具和剪刀刃。
Surfacing welding can be used to repair the local damage and wear a larger forging die, after surfacing hardness of HRC45 or more. Spray welding can be used in smaller wear (1 to 3 mm) on the mold, can also be used to strengthen the newly manufactured mold. EDM can be used to reinforce cold dies and scissors blades.
