摘　　要：介绍金属磁记忆方法用于焊缝检测的特点。焊接件实际应力 应变状态的快速检测显示了金属磁记忆方法的优越性 。The characters of the application of metal magnetic memory(MMM) to the inspection of welded joints were described. The advantages of MMM were shown in nondestructive testing of welded joints for their stress strain state and flaw. Typical application examples were also given.

关 键 词：磁性检测 磁记忆材料 焊缝 缺陷 应力集中
