Abstract
Surfacing is conducted with horizontal electro-slag welding by using a strip electrode, and by applying a magnetic field, having component perpendicular to a base metal, to a molten metal and slag pool to control the flow of the molten pool.
Claims3
In a method for surfacing with horizontal electroslag welding by using a strip electrode, the improvement comprising arranging at least one solenoid, magnetized by direct current, adjacent to the strip electrode, and applying magnetic fields, having components perpendicular to a base metal, to both sides of molten pool of metal so that the magnetic fields act in mutually opposite directions at both sides of the molten pool, whereby molten metal flows toward both edges of the pool in the width direction of the electrode.
