侧面溶深
A closed-loop control system with welding current as control parameter is founded to control the width of isothermal line of back-side welding temperature field in TIG welding of thin plate. The control of penetration and width of back side weld is achieved.
以焊接电流为控制量,研制了薄板钨极氩弧焊(TIG)背面温度场等温线宽度闭环控制系统,实现了对焊缝背面熔宽和熔透的控制。
But the French side may bemoan a lack of penetration and risk-taking on their own patch when this tie draws to an end.
但法国球队在自己的场地上也没有什么穿透力和有威胁的进攻。
