掘进机用防爆电机水冷机座焊接工艺探讨

A Discussion of Welding Craft of Hydrocooling Frame of Explosion-proof Motor for Roadheader

掘进机机座焊接质量不稳定,采用自动焊接提高焊缝质量。通过工艺改进和对应措施的实施,机座焊缝质量和焊接尺寸精度已经稳定提高。

Since the quality if weld joint in roadheader is not.steady, automatic welder shall be adopted. The quality of the weld joint and the precision of the welding dimensions have improved a lot by strengthening the craft and associate measurements.
