我编辑部先后收到了全国各地、各工矿企业许多焊工的来信,了解有关焊工入门的指导性问题。由于人力有限,不能一一回复,在此请我所焊工培训室的同志就有关问题作一简单介绍,仅供参考。 My editorial department has received letters from many welders from all over the country and from various industrial and mining enterprises to learn the guiding questions about welder’s entry. Due to limited manpower, we can not reply one by one. In this regard, my comrades at the welder’s training room should give a brief introduction on the relevant issues for reference purposes only.
