<p>PURPOSE:To improve the reliability and safety of parts by working a U groove of a specific width on a steel disk, welding this groove as a bevel groove by MIG welding using a consumable type electrode for stainless steels and executing a welding procedure to the size of the surface height of the final layer lower by a specific value than a base metal. CONSTITUTION:The narrow groove of 9 to 11mm width is formed as the groove to be formed for MIG welding of the steel disk. The welding is executed on one pass per layer in this groove by using JIS Y309 or Y309L as the consumable electrode for stainless steels in such a manner that the height of the final surface of the weld metal is lower by >=1mm and <=3mm than the surface of the base metal. The magnetic permeability necessary as the magnetic shielding parts is not obtainable with Y308 and Y308L which are relatively low in the content of Ni and Cr or Y316 and 316L contg. Cr at a lower ratio and contg. Mo. The nonmagnetic part which has sufficient joint strength and has the stable and low magnetic permeability is provided in a part of the steel disk of the magnetic shielding parts in this way. The reliability and safety of the magnetic shielding parts are thus greatly improved.</p> |
