摘要

Tube and shell condenser is an important component of soybean softening equipment, and its structure is Q235B welding with 304 austenitic stainless steel pipes. During the using process of this product, it appears crack failure. In order to find the reason of crack failure, the welded joint was analyzed by SED, XRD, EDXRF and metallographic microscope in detail, and some improvement measures and solutions are put forward to avoid crack failure in this paper.
