对TC1钛合金激光焊接工艺及接头性能进行研究。通过设计拖罩及专用夹具 ,较好解决了焊接熔池的保护 ,获得了无气孔、裂纹 ,表面无氧化的银白色焊接接头。熔透 1 .5mm的板材 ,焊接速度可达 3m/min .。接头横截面形貌为“沙漏”状。通过组织和力学性能分析发现 ,尽管组织较粗大 ,焊缝仍具有较好的综合性能
The research on TC1 titanium laser welding technology and joint performance. Through the design of drag and special fixtures, it solves the problem of weld puddle protection and obtains silver-white welded joints without air holes, cracks and no oxidation on the surface. Infiltration of 1.5 mm plate, welding speed up to 3m / min. Cross-sectional shape of the connector “hourglass” shape. Through the analysis of the organization and mechanical properties, it is found that although the structure is coarse, the weld seam still has good comprehensive performance
