ABSTRACT:
In arc butt welding the arc is moved between the faces of the parts to be joined by a magnetic field. In order to insure the arc travels over the whole of the faces to be welded the parts are moved generally parallel to the faces so that the overlapping area of the faces changes during the arc heating.
