X80管线钢自保护药芯焊丝自动焊工艺试验研究
Study on the Automatic Welding Process Experiment of X80 Pipeline Steel Self-shielded Flux-cored Wires
摘要
Abstract
Aiming at the X80 high strength pipeline steel and related welding technical specification requirements,it adopted independent development eight welding torch internal welder and self-shielded flux-cored wire automatic welder to carry out pipeline all-position welding test,and conducted mechanical properties testing of welded joints. It determined reasonable groove type,welding wire type and matching welding parameters,and formulated welding technology internal welding machine for root welding+self-shielded flux-cored wire automatic welding for fill and cover welding. The test results proved that the welding process is reasonable,simple operation,and high efficiency,the various performance indicators of welded joints all meet the X80 steel grade pipeline engineering welding specification and relevant national standards.关键词
