摘要
基于CSR油船规范中禁止舭龙骨垫板的对接缝与船体外板直接连接的条款,结合现有的对接焊工艺无法确保每次焊接都满足规范要求的现状,设计一种新型焊接垫片。焊接试验验证表明,对接焊缝能满足规范要求,降低了焊接难度,改善了对接焊工艺。
Based on CSR-OT Rule＇s requirement of that direct connection between ground bar butt welds and shell plating is to he avoided, and existing butt welding procedure can not ensure 100 percent satisfying the rule＇s requirement, a new type welding backing was designed. The welding test proved that the butt welding satisfies the rule＇s requirement and the welding diffi- culty is reduced, butt welding procedure is improved as well.
