Abstract
PURPOSE:To improve the creep rupture strength of a joint by forming the layer of an isometric crystal grain by agitation welding at the pipe inner face side at least of the groove of the butt part of an austenitic heat resistant alloy pipe. CONSTITUTION:An exciting coil 2 is provided around an electrode 1 and connected to the AC power source 3 for exciting. On the other hand, the electrode 1 and a base metal 4 are connected to the power source 5 for welding. By doing so a molten pool 6 becomes a fine grain structure with its solidification with being stirred by acting the Lorenz's force of the welding current and alternate magnetic field on the molten pool 6. Therefore, once the conditions on the magnetic agitation be decided the welding metal can be made in a fine isometric crystal. Also as the welding method either method of TIG, MIG, submerged arc welding, etc., is available.
