Abstract
PURPOSE: To form good bead shapes and obtain weld zone of high quality by using the flux which forms high-viscosity slag at the fusing and tilting AC arc forward to the preceding electrode side by a magnetic field at the time of making submerged arc welding of the weld line of a spiral steel pipe or the like by using DC and AC arcs to the preceding and succeeding electrodes.
CONSTITUTION: DC and AC arms are used for preceding and succeeding electrodes 5a and 5b respectively and an electromagnet 15 is so disposed as to sandwich the succeeding electrode 5b at the tandem submerged arc welding of the case when the weld groove of the materials 14 to be welded is inclining as in production of spiral pipes. The flux which forms high-viscosity slag is built up on the groove surface. Next, the succeeding arm is deflected (arc is tilted forward) by the electromagnet 15 and is excited by AC similarily to the succeeding current. This method enables high speed inclined position welding to be performed and prevents the production of weld defects such as undercuts, etc.
