摘　　要：研究了00Cr26Ni6Mo4CuTiAl不锈钢的焊接性及其焊接工艺问题，在熔敷金属强度低于母材的情况下，预热到200℃，以低的线能量（0．78kJ／mm）施焊，可以得到无裂纹的焊接接头；其机械性能略低于母材，热影响区的耐点蚀性能与母材相当．The weldability and welding technology of the stainless steel00Cr26Ni6Mo4CuTiAl was studied. As it turned out that when the strength of the welddeposit was lower than the base benal, the cracking-free welding joint could beobtained through preheating (200℃), by controlling the temperature between two passes(＜200℃) and selecting low heat input (0.78KJ/mm). Its mechanical properties wereslightly lower than base material, and the pitting corrosion resistance was equal to thebase material.
