摘要
介绍和讨论了CO_2气体保护陶质衬垫WQT—1的单面焊接工艺;分析了影响衬垫单面焊接工艺过程及反面焊缝成形的各种因素,如:坡口根部间隙、坡口角度、错边量、钝边高度、操作方法、焊接参数、接头处理、定位焊缝等,确定了最佳装配间隙和坡口角度。
This paper discusses in detail the one side welding technology for CO_2 gas shielde arc welding of the ceramic gasket WQT—1, and analyses all factors influencing the welding process and the forming of back welded seams, and decides on the best assembly gap and the groove angle.
