钼镧合金杆焊接质量研究

Welding Quality of Mo-La Alloy Rods

分析了钼镧合金杆在电阻对焊中焊接接头的形状、金相组织、抗拉强度、硬度等主要特性指标。研究表明影响焊接接头质量的主要控制难点为焊缝及焊缝根部的组织状态;对焊机中的焊接能量、锻压力、冲程为影响焊接接头质量的关键因素。

The shape,microstructure,tensile strength and hardness of the joint of Mo-La alloy rods in resistance butt welding were analyzed.The results show that the microstructure state of welded joint and the weld root are the main control difficulties affecting the quality of welded joint.The welding energy,forging pressure and stroke are the key factors affecting the quality of welding joint.
