PURPOSE:To prevent embrittlement of a weld zone and deterioration of corrosion resistance by inserting the titanium clad steel plates into a gap part formed by notching after welding as spacer materials and plasma-welding the different material weld zone by using Ag-Cu-base filler metal in an inert gas atmosphere. CONSTITUTION:In performing fillet welding or butt welding on the titanium clad steel plates 1, notching is provided along with a groove on the end faces of the respective titanium clad steel plates 1. After base metals 2 are subjected to fillet welding or butt welding on the groove part, the titanium clad steel plates 1 are inserted into the gap part formed by the notching as the spacer materials 6 and the different material weld zone 11 is subjected to plasma welding by using the Ag-Cu-base filler metal in the inert gas atmosphere. Consequently, weld metal without being accompanied by the embrittlement of the weld zone and the deterioration of corrosion resistance can be obtained by arc welding same as before. |
