摘要:
某型号火药起动器壳体采用新材料1Cr11Ni2W2MoV，需要进行焊接工艺研究。针对此产品进行了自动TIG焊工艺试验，对比了S-659和HGH367两种焊丝以及不同焊接电流、焊接速度配合所焊焊缝的组织及性能。结果表明，采用S-659焊丝以及大电流高速焊的“大规范”的焊接参数所焊焊缝，成形、组织及性能均更优，焊缝质量满足QJ1842-95 Ⅰ级要求。在此基础上进行了产品模拟件及正式产品的焊接，所焊产品经X光检查合格，液压、气密试验考核合格，满足使用要求。
Abstract:
Welding technology research is needed for gunpowder starter's shell made from new material 1Cr11Ni2W2MoV. Weld structures and performances of the welded joints made through with S-659 and HGH367 welding wires as well as different welding currents and welding speeds were compared after automatic TIG welding tests. The results indicate that the weld shaping, structure, organism and performance of the welded joints made through with S-659 welding wire, large welding current and high welding speed are more excellent, which can satisfy LevelⅠrequirements of QJ1842-95. The simulated and practical products welded with this method were qualified. The result was got by X-ray detection, hydraulic and air-tight tests. They can meet the use requirements.
