Abstract

PURPOSE: To enable one-pass, one-run welding process, providing high efficiency and good welded zone in horizontal electrogas automatic welding, base material is attached with special back metal and a curved torch is used in a specified method.
CONSTITUTION: A glass fiber material 16 and a copper plate 5 are attached on the back of upper plate 4a having narrow groove of 5 to 13mm width. The top surface of lower plate 4b is attached with a water-cooled copper plate 13 having a shield nozzle 13a. Torch 14 having curvature (R=70 to 120mm) tip 14a is inserted into the groove. A fine wire 10 is pressingly curved and sent at angle of θ3 (90±30 degrees) to the plate thickness direction. The torch 14 is arranged at θ2 (0 to 20 degrees) to the horizontal surface of the lower plate 4b. Automatic welding is conducted while vibrating the torch at 60 to 1000 cycle/min and feeding shield gas. Arc force causes molten steel to reach the top plate surface 4a, producing convection flow of holding angle θ4 (40 to 80 degrees), enabling one-pass, one-run welding of high efficiency and good welding.
