1.6mm规格的焊丝用于低碳钢铸件的焊接工艺

Welding processes of size 1.6 mm wilding wire used in mild steel casting

介绍了低碳钢铸件焊接中,使用φ1.2 mm规格的焊丝时存在的不足,通过试验验证使用φ1.6mm规格的焊丝焊接时对铸件质量、效率、成本的影响,并确定了φ1.6 mm规格的焊丝焊接时的焊接工艺,认为φ1.6 mm规格的焊丝可在低碳钢铸件缺陷焊接中广泛使用。

Deficiencies existing in mild steel casting welded used the wire with diameter of 1.2 mm were introduced in this paper. Effects of casting component welded with the wire of 1.6mm in diameter on the quality, efficiency and cost of its welded structure was verified by experiments, and finally it can be concluded that wire with diameter of 1.6 mm can be widely used in the welding of mild steel casting. The welding parameters were confirmed through the experiments concurrently.
