Study on ductile fracture behavior of welded joint of one side welding with ceramic backing 陶瓷衬垫单面焊接接头的韧性断裂行为研究
The distinguishing features of welding and control method of welding deformation for welding of H section steel are introduced. The welding condition of automatic submerged arc welding with flux backing is determined by the test of welding technology. 介绍了H型钢的焊接特点及焊接变形的控制方法,并通过焊接工艺试验确定了带焊剂垫埋弧自动焊的焊接工艺参数。
Cause Study of Porosities Formation in Semiautomatic CO_2 Arc Welding by One Side with Ceramic Backing Strip PROTECTION OF MARINE SHIPS: STATE OF THE ART IN CHINA 船舶焊接CO2气体保护单面焊气孔成因探讨
Through the welding technology experiment about rear forcible figuration with ceramic backing, lux-cored wire, and mixed gas shielding, the influences of main normative parameters and technical factors on rear figuration were analyzed. 通过对陶瓷衬垫药芯焊丝混合气体保护背面强制成形的焊接工艺试验,分析了主要规范参数和工艺因素对背面成形的影响。
Thus proposed one-side welding with back formation of robot, backing welding is the key procedures of the entire welding process. 由此提出机器人单面焊双面成形焊接技术,其中打底焊是整个焊接过程的最关键步骤。
