摘要

采用中间过渡层的新方法研究了黄铜焊接气孔的控制, 对比分析了以紫铜为中间层的黄铜激光焊接和常规激光焊接获得的焊缝的气孔率, 结果表明:在中间层条件下, 焊缝表面和内部的气孔率均大幅降低; 随着焊接速率增大, 气孔率逐渐减小, 当焊接速率为2.2 mm/s时, 气孔率几乎为零; 当焊接参数相同时, 中间层条件下的焊缝气孔率仅为常规激光焊接的1/3, 焊接接头的力学性能优于常规激光焊接。在焊缝成形良好的前提下, 验证了采用紫铜为中间层的焊接方法控制黄铜激光焊接气孔缺陷的有效性。

Abstract

The control of brass welding porosity is studied by adopting a new method of the intermediate transition layer. The weld porosities of brass laser welding under the copper intermediate layer condition and brass general butt laser welding are contrasted and analyzed. The research results reveal that the porosities of weld surface and weld interior are greatly reduced under the condition of the intermediate layer. As the welding speed increases, the porosity decreases gradually. The porosity is almost zero when the welding speed is 2.2 mm/s. When the welding parameters are the same, the porosity of the weld under the intermediate layer condition is barely one third of that in the normal butt laser welding of brass sheet. The mechanical properties of welded joint obtained at the intermediate layer condition is superior to that of welded joint obtained at normal butt laser welding. Under the premise of good weld formation, the effectiveness of the new method of the copper intermediate layer to control the porosity defects of brass laser welding is verified.
