Fatigue life is able to increase more than 90 % as using technique that makes beadforming on the back side.
采用背面成形技术使膜盒的疲劳寿命提高90%以上。

Through experimental measuremnet, the optimum current and gas flow rate for strictly controlling the beadforming process are found out.
通过试验证明,严格控制焊接电流和离子气流量,可以对焊缝成形进行有效控制。
