    摘要: The object of this invention is to prevent the occurrence of welding defects such as undercuts, overlaps and faulty angles of fusion, and to increase the efficiency of welding in the horizontal position. Auxiliary wires 5a and 5b are inserted into molten pool 12, and a unidirectional current is made to flow between them. A magnetic field 9 is induced which is approximately orthogonal to the surface of the parent material so as to generate an upward Lorentz force (opposite the pull of gravity) in molten pool 12. This force supports the molten metal and prevents it from dripping, resulting in a better-shaped bead.

    摘要: The object of this invention is to prevent a defect which occurs in overhead or vertical welding when gravity causes molten metal to drip downward so that the top of the gap has an undercut and the bead has a bulge along the weld line (i.e., a convex bead is created). During overhead or vertical welding, a unidirectional current is made to flow in the molten pool in the direction of the weld line. When the aforesaid current flows in conjunction with a magnetic field, a Lorentz force is exerted in the molten pool in an upward direction towards the upper top side of the groove. This prevents the molten metal from dripping downward and improves the shape of the bead.

    摘要: A clad welding method, which can prevent the occurrence of incomplete fusion, and can cover the surface of a base material over a wide range with a weld metal, while suppressing the dilution of the weld metal, by use of a relatively simple technique, is provided. For this purpose, a welding heat input is increased at a location where one end (10a) of a preceding weld bead (10) and the other end (20b) of a succeeding weld bead (20) overlap, as compared with a welding heat input at a location where the preceding weld bead (10) and the succeeding weld bead (20) do not overlap, to produce a deep penetration portion (12a) involving locally deep penetration (12).

    摘要: A pair of upper and lower electrode wheels 1, 2 are disposed so that their axes 17, 18 are tilted in a horizontal plane in respective directions opposite to each other with respect to a straight line Y perpendicular to a welding line X defined on overlapping portions (L) of two metal plates 5, 6, and mash seam welding is performed while positively driving electric motors 61, 62. This can reduce the increased amount of thickness and step gradient of a joint portion to reduce a stress concentration factor and ensure joint strength. The metal plates are joined to each other such that a nugget N is not deviated from a joint interface. Therefore, it is possible to prevent respective ends of the metal plates at the overlapping portions L from biting into and scratching the corresponding electrode wheels 1, 2 and to prevent spattering during the welding.
