摘要
针对LY12铝合金焊接接头强度下降的问题,采用交流TIG焊方法,通过试验改变TIG焊工艺参数,并测试其抗拉强度和硬度,研究焊接工艺与接头强度之间的关系。
Aiming at the problem of decreasing strength of the LY12aluminum alloy welding joint ,AC TIG welding is adopted.By changing TIG welding technical parameters and checking the anti-pulling strength and hardness of the joints,the relationship between welding techniques and strength of joint is researched.
