摘要： PURPOSE:To achieve the imprivement in product grade and the captioned welding efficiency by respectively setting the welding current according to plate thicknesses, the torch speed according to welding currents and the torch angle according to the angles of inclination of welding members and continuously welding edge joints toward the sloped part. CONSTITUTION:After the tack-welded members 15 are placed in the home position on a surface plate 2, the members 15 are fixed by means of end part holding jigs 14 and restraining jigs 13. The edge joints 15a of the members 15 have horizontal parts 15a2 and sloped parts 15a1. A sensor 11 is applied to the flange surface by controlling the gear mechanism 7a for position controlling in order to position the center of each torch to the respective centers of the edge joints 15a. After this positioning, the welding current is set according to the thicknesses of the members 15 to a welding power supply and the moving speed of a torch 12 is set to a variable speed drive unit 5b according to the welding current. The angle beta of the torch 12 is set according to the angle alpha of inclination of the tapered part 15a1. An automatic TIG welding device 1 is then moved from the part 15a2 to the part 15a1 under controlling with a tracing device 10, whereby welding is accomplished.

摘要： PURPOSE:To eliminate the need for a backing strip and to obviate dropping of a molten filler metal from the groove part formed between base metals by inserting the belt-like filler metal into the bottom aperture of the groove part to close the aperture then welding the groove part. CONSTITUTION:A single Vee groove 2 is formed to the joint parts of base metals 1, 1 to be joined and a belt-shaped filler metal 8 bent to the V shape to meet the shape of the groove 2 is inserted into the groove 2 from the upper part thereof in a way as to close the bottom aperture 5 of the groove 2. An electrode 6 is then positioned in the groove 2 and the groove is welded. The filler metal 8 melted by welding solidifies while forming a molten pool together with the supplied filler metal thereby forming a weld bead. The penetration bead is formed in the groove 2 in the above-mentioned way and thereafter the beads are further formed thereon.

摘要： PURPOSE:To obtain a homogeneous weld zone in the direction of the plate thickness of base metals by specifying the average speed and a ratio of the minimum speed to the maximum speed of the arc shaking in a prescribed range of the plate thickness with the center of the plate thickness of the base metals of an arc shaking path as a center at the time of the horizontal electro-gas welding. CONSTITUTION:As to the horizontal electro-slub welding, a welding torch is shaked nearly in the direction of the plate thickness of the base metals and moved in the horizontal direction. On this occasion, as to the shaking of the welding arc, the average shaking speed of the arc in the range A of 1/3 of the plate thickness T is made lower in the range of 20-50% than the arc average shaking speed in the ranges Ba and Bb out of the range A with the central part of the plate thickness T of the base metals as a center. Furthermore, as to the shaking speed of the arc in the range A, the ratio of the minimum shaking speed to the maximum shaking speed is made >=0.5 to perform the welding. In this way, the homogeneous weld zone can be formed in the direction of the plate thickness of the base materials.
