有关焊接裂缝的分类和形成裂缝的各种不同论点,在“焊接”第10期唐慕尧同志“关于焊接中的裂缝问题”一文里已有详细的论述,因此在这方面就不再重复。本文只是在形成焊接裂缝的原理方面稍加补充,并提出一些具体的资料,另外着重介绍几种裂缝试验机和焊接时防止裂缝所采取的措施。希望通过讨论,能够对生产及研究工作提供一些必要的参考资料和正确解决问题的方向。
Various points of argument about the classification of welding cracks and the formation of cracks have been discussed in detail in Comrade Tang Muyao’s “Cracks in Welding”, Issue 10 of “Welding”, and therefore will not be repeated here. This article is only in the formation of the principle of welding cracks a little supplement, and put forward some specific information, while highlighting several crack testing machine and welding cracks to prevent the measures taken. We hope that through discussion, we can provide some necessary reference materials for production and research work and the correct direction for resolving the issue.
