Welding in power equipment: Present and future

A brief summary of automatic welding in manufacture of membrane walls for pressure parts of power equipment is presented. Problems of current state and possible expectation in this key technology of welding were analyzed. Analyses of material aspects of welding the progressive steel type 23 are presented. Weld heat treatment effect on creep resistance were examined. Problems of T23 steel tube weld-ability and conclusions from practice are shown.
