Analysis of T-joint weld shaping characteristics and influencing factors by laser-TIG hybrid welding titanium alloy

  • 摘要: 采用激光-TIG弧复合焊接工艺对钛合金T形结构单面焊背面双侧一次成形焊接新技术进行了研究,通过综合试验、对比分析等方法,研究了多种试验条件下T形结构焊缝成形特点及影响因素,给出了采用激光-TIG复合焊接工艺实现钛合金T形结构单面焊背面双侧一次成形焊接的最佳工艺方案.结果表明,采用激光-TIG复合焊接工艺焊接钛合金T形结构与钨极氩弧熔透焊工艺相比在焊缝组织、焊接效率、焊缝成形、间隙适应性等方面有明显的优势.

     

    Abstract: A new laser-TIG(laser beam and tungsten inert gas) hybrid welding procedure for titanium alloy T-joint structure called single pass welding and double backside shaping technology is proposed.The forming properties of the T-joint structure is analyzed and discussed under different testing conditions by a series comparative welding experiments to reveal the optimal scheme of single pass welding and double backside shaping with laser-TIG hybrid welding for titanium alloy T-joint structure.The results indicate that comparing with the TIG melt through welding methods,the proposed single pass welding and double backside shaping technology based on laser-TIG hybrid welding procedure for titanium alloy T-joint structure is obviously advantageous in weld forming,weld microstructure,weld composition,weld property,welding efficiency and the tolerance to gaps between plates.
