摘要
Abstract
The welding performance of super-thick SA387 Gr1 1 Cl2 steel plates was analyzed.Aiming the problems of cold crack,reheat crack and not easy molding in vertical welding process,the detailed welding procedure and welded were formulated.By studying chemical composition and mechanical proper-ties of the joint,the applicability of this welding procedure was evaluated.The results show that we can get high-quality welded joint of the super-thick SA387 Gr1 1 Cl2 steel plates by using the electrodes of PHOENIX CHROMO 1 and many other technological measures as below:double U groove;preheating be-fore welding;small current;short electric arc;multi-layer and multi-pass welding;zigzag electrode ma-nipulation;hydrogen elimination immediately after welding;the overall stress relief heat treatment;rapid heating and cooling in the temper brittleness transition temperature range.关键词
