针对10mm厚TA1工业纯钛开展高效的、低成本的潜弧焊工艺试验研究。研究结果表明：氦气可有效增加焊缝熔深，通过合理匹配焊接工艺参数，采用纯氦气一次可熔透10mm厚TA1钛板，获得成型美观的焊接接头；拉伸试验结果表明：TA1纯钛潜弧焊接头抗拉强度略低于母材的抗拉强度，可达到母材的93.4%，拉伸试样在显微组织为柱状晶的焊缝区断裂。

TA1 commercial pure titanium with 10mm thick was welded by high efficient and low-cost submersible arc welding. The results showed that, using helium as shielding-gas can remarkably improve weld penetration. The high quality welded joint was obtained and the titanium plate of 10mm thick TA1 can be penetrated by using appropriate parameters and pure helium gas. The tensile test results indicated that, the tensile strength of submersible arc weld joint is as high as 93.4 percent of that base metal, slightly lower strength than base metal. All tensile samples fractured at weld zone, which zone consists of columnar grain.
