我厂的主要产品是化工压力容器,为提高焊接生产效率,以前曾试验用实芯焊丝CO_2气体保护焊代替部分手工电弧焊的焊接工作,但由于较容易出气孔,难于稳定地达到X射线探伤的要求,故未能推
I plant the main product is a chemical pressure vessel, in order to improve the welding production efficiency, previously experimented with solid wire welding CO2 gas shielded welding instead of part of the manual arc welding, but due to the more easy vent, it is difficult to achieve stable X-ray detection The request, therefore can not push
