Abstract

PURPOSE:To obtain a weld zone which can be utilized to obtain metal Cr structural material excellent in the mechanical property by providing the ratio of the area of a blowhole to the cross-sectional area of a weld zone to less thus a prescribed value. CONSTITUTION:The area of the blowhole at the cross section of the weld zone of metal Cr of this invention is <=1.0% with respect to the cross-sectional area of the weld zone. since said blowhole is caused by cohering of hydrogen contained in the metal Cr at the time of welding, it is necessary to perform welding while eliminating said hydrogen. For this purpose, inert gas containing oxygen is used as shielding gas or atmosphere gas for said weld zone and the metal Cr is obtained by performing TIG welding or MIG welding. In this case, it is preferable to provide 0.1-10.0% capacity % oxygen concentration and hydrogen content <=50ppm for the metal Cr to be used for welding. In addition, it is preferable to use He, Ar, etc., which do not give an influence on the weld.one as the inert gas.
