摘要
论述了激光焊接连接防护罩和螺母的优越性。采用激光焊接的方法分别研究了Q235钢和H62黄铜防护螺母激光焊接后的组织和性能。研究结果表明,防护螺母激光焊接成形具有最窄的热影响区和最小的组织长大倾向,硬度梯度平缓,且防护罩几乎没有变形。
The superiority of the connection of nut with protection by laser welding is expounded. The method of laser welding is used to study the organize and performance of Q235 steel and H62 brass protective nut connected by laser welding respectively. Test results show that the format/on of protective nut by laser welding have narrow heat affect zone and minimum organization grow up inclination, gentle hardness gradient, and the protective cover is nearly not out of shape.
