Abstract

PURPOSE: To enable one-pass, one-run welding process, providing high efficiency and good welded zone in horizontal electrogas welding, special back metals are attached onto the top and back of groove surface, and a curved torch is used in a specific manner.
CONSTITUTION: A groove with 5 to 12mm gap is formed on materials 1 and 5. On the material surface sides 2, 6, L type cooling plate 11 is placed so that its elevated corner 15 meets the groove surface 8, and the recess 16 is spaced from the material 1 with a distance g. To the material back surface 3, 7, a channel-type back member 31 is fixed so that it contains a refractory 37 spacedly from the material 1 with a distance C. R-curvature tip 52 is used to place a wire 53 with ±30 degree to weld line 1, and with angle θ1 (0 to 20 degrees) to the groove 8 of the material 2. Welding is conducted while giving vibration of specific frequency and amplitude W, and feeding CO2 through pipe 28. Welding metal is caused to circulate between the groove 4, 8, providing one-run, one-pass, high-quality, single layer welding.
