摘要

在船舶建造过程中，焊接修复在造船业中被广泛使用。焊接过程中产生的残余应力分布对船舶结构的修复效果有重要影响。本文对船舶和海上结构物中常用的板件补焊引起的残余应力分布进行了实验研究。评估不同的修复技术，以确定与残余应力值相关的最佳实践。对补焊的建议进行了讨论，并对目前的做法提出了修改意见。

Experimental Analysis of Repair Welding Alternatives for Shipbuilding DH36 Plates

Repair by welding is widely used in the shipbuilding industry during ship construction. The effect of the residual stress distribution induced by the welding process on the ship structure is important for the repair effectiveness. This article presents an experimental study of the residual stress distribution induced by repair welding in the plates that are typically used in ships and offshore structures. Different repair techniques are evaluated to identify the best practice associated with residual stress values. Recommendations for repair welding are discussed, and modifications to the present practice are proposed.

期刊介绍： Original and Timely technical papers addressing problems of shipyard techniques and production of merchant and naval ships appear in this quarterly publication. Since its inception, the Journal of Ship Production and Design (formerly the Journal of Ship Production) has been a forum for peer-reviewed, professionally edited papers from academic and industry sources. As such, it has influenced the worldwide development of ship production engineering as a fully qualified professional discipline. The expanded scope seeks papers in additional areas, specifically ship design, including design for production, plus other marine technology topics, such as ship operations, shipping economic, and safety. Each issue contains a well-rounded selection of technical papers relevant to marine professionals.
