概要

• 論文の詳細を見る

• Existing wet process with stick electrode has the limitation that reliable welds can not be obtained. To improve this problem, the authors have been developing water curtain type underwater CO_2 arc welding, which consist of dual nozzle, that is, shielding gas flows out from inner nozzle and curtain water flows out cylindrical from outer nozzle. Materials used were 4.5, 6, 20, 40 mm thick mild steel. By this method, single pass and multi pass butt welding were carried out in the fresh water. Successful results were obtained both in tensile test and bending test.
