摘要

钛合金被誉为钢和铝之后的“第三金属”,具有密度小、比强度、刚度高、耐腐蚀性好等特点,被广泛应用于航空航天、轨道交通等领域。随着装备制造业的高速发展,对钛合金材料的需求越来越大,因而对钛合金结构的焊接制造工艺也提出了更为苛刻的要求。本文综述了钛合金焊接技术的发展现状,包括激光填丝焊、激光-电弧复合焊、熔化极惰性气体保护焊、氩弧焊等研究内容,并对钛合金的新型焊接技术发展趋势进行了展望。研究发现,传统焊接工艺如熔化极惰性气体保护焊和新型焊接工艺如激光焊均可以运用于钛合金焊接中,传统焊接技术使用和维护成本较低、焊接效率更高但焊接接头成形较差,因此更适用于制造大型钛合金部件;新型焊接工艺的焊接接头成形更为良好但焊接效率偏低且设备使用和维护成本更高,因此更适合精密钛合金部件的生产。

Abstract

Titanium alloy is known as the “third metal” after steel and aluminum. Due to the characteristics of low density, high specific strength, high stiffness and good corrosion resistance, it is widely used in aerospace, rail transit and weapon military industry. With the rapid development of equipment manufacturing industry, the demand for titanium alloy materials is increasing, so more stringent requirements are put forward for welding manufacturing process of titanium alloy structures. The development status of titanium alloy welding technology was reviewed, including laser filler wire welding, laser-arc hybrid welding, metal inert gas welding, argon arc welding and so on. The development trend of new welding technology of titanium alloy was prospected. It was found that traditional welding processes such as metal inert gas welding and new welding processes such as laser welding could be used in titanium alloy welding. Traditional welding technology had lower use and maintenance costs, higher welding efficiency but poor weld formation, which made it more suitable for manufacturing large titanium alloy parts. The welded joints of the new welding process were more well-formed, but the welding efficiency was low and the equipment use and maintenance costs were higher, which made it more suitable for the production of precision titanium alloy parts.
