分段制作焊接裂纹原因分析及预防措施

Cause Analysis and Preventive Measures of Welding Crack in Section Fabrication

概述某船厂在分段制作外检过程中发现多处焊接裂纹,对产生焊接裂纹的分段进行探伤检测和专题研讨分析,找出焊接裂纹的种类和主要影响因素,制定预防措施。杜绝后续船分段制作过程中类似问题重复发生,为其他造船企业焊接质量管理提供参考。

Several welding cracks are found in the process of section fabrication inspection in a shipyard.Flaw detection and topic study and discussion are done on the sections with welding cracks.The types of welding cracks and the main influencing factors are found out and the preventive measures are worked out.Similar problems are expected to be avoided in the following section fabrication process.It offers reference for the welding quality management in other shipbuilding enterprises.
