摘要
传统的焊接工艺用于薄壁容器的焊接虽然实用,但是当筒体壁厚超过40 mm时就会使坡口宽度增大,焊接层数增多,影响焊接质量。文章论述了通过改变传统的容器焊接的坡口型式,简化焊接方法,并对相应的焊接设备进行改造,来显著提高厚壁产品焊接效率的途径。
Traditional welding process is practical for welding thin wall vessels,but it influences the welding quality of vessel with wall thickness greater than 40 mm due to increased bevel width and welding layers.This paper discusses the approaches of boosting welding efficiency of thick wall vessels,including altering traditional bevel pattern,simplifying welding method and reforming corresponding welding equipment.
