Abstract
PURPOSE: To make good penetration beads formable despite the presence of tack weld beads in particular by forming tack weld beads to a linear shape by MIG welding of low heat input, then performing welding in such a manner as to form penetration beads from the top layer of these tack weld beads by the welding of the next layer.
CONSTITUTION: The 1, 1' in the figure are materials to be welded, 2 is a backing strip such as copper plate 3, is a backing strip consisting of flux or glass fiber provided between the bottom surfaces of the materials 1, 1' and the plate 2. The method of this invention first involves forming linear tack weld beads 4 by MIG welding of low heat input. Next, next layer beads 5 are formed by large current MIG welding from the top layer of these tack weld beads 4. The beads after the beads 5 may be formed by submerged arc welding other than large current MIG welding. As a result, the welding for forming the next layer beads is accomplished by making welding current constant, and therefore the stability of the arc is good, and the occurrence of defects in the penetration beads in the tack welded part and near the same as in the prior art is obviated, thus the one side welding of low temperature steel materials is accomplished in a good state.
