| Automatic-Controlled Circumferential MAG Welding System for Pipeline Construction Tomoya Fujimoto, Noboru Fukuhara |
|
Synopsis : An automatic-controlled MAG welding system which incorporates expert programs simulating professional skills and know-how has been developed and applied to field welding. The principal results work were: (1) Joining efficiency was nearly double that with conventional SMAW, (2) the quality of welded joints was excellent with few variations, and (3) further labor savings associated with a higher arc time rate are desired. The new system also holds considerable promise for alleviating dirty, dangerous, and hard work conditions in pipeline construction. |
