Research on Full Position Automatic Welding Technology for Oilfield Water Injection Pipeline
In response to the challenges of high labor intensity,low efficiency,high cost,and difficulty in ensuring welding quality in manual welding of oilfield water injection pipelines,a full position automatic welding technology for water injection pipelines was developed.According to different shielding gas ratios of 80%Ar+20%CO2,100%CO2,welding materials were se-lected and matched,and two sets of welding process evaluation tests were conducted on specimens.The results show that the sur-face appearance inspection and non-destructive testing of the two test welds were qualified,and the tensile and bending require-ments met the standard specifications.Based on comprehensive factors such as the construction site environment,welding opera-bility,and welding forming quality,a reasonable welding process was determined.In multiple engineering applications,the wel-ding appearance and forming quality are good,and the first pass rate of welding is high.
