Abstract
PURPOSE:To reduce the thermal strain and to improve the welding accuracy by forming the titled welding machine of a rotational electrode device which is arranged freely rotatably and travelably along the outside surface of a work and a tabular strap arranged in opposition to an electrode ring with a weld zone between to radiate effectively the excessive heat generated on the weld zone. CONSTITUTION:The weld zone WO of the work W is fixed on the tabular strap 8b by pressing both side parts thereof by welding clamps 8a and 8a. Then, an electric current is applied to between the electrode ring 5a and the strap 8b and the Joule heat is generated on the weld zone WO and base metal is molten and the weld zone WO is seam-welded along with the rolling of the electrode ring 5a. During this time, the heat by which the weld zone WO is molten is rapidly radiated to the outside through the strap 8b, the clamps 8a and 8a and electrode clamps 5b and 5b. By this method, a heating region of the work W is limited in only the vicinity of the weld zone WO and the thermal strain can be reduced. In addition, it is eliminated to heat the weld zone WO up to the extremely high temperature and the deterioration of stabilization of weldability due to an increase of electric resistance is prevented and stable welding is performed.
