现代焊接生产的主要发展方向之一是将与焊接构件生产有关的各个环节都逐步过渡到综合机械化和自动化,这样可以保证劳动生产率大幅度增长,改善焊工的劳动条件,提高生产效率和焊接构件的质量及可靠性。在制造焊接构件的总工作量中,焊接本身仅占15～20%。因而,综合机械化和自动化只有在同时包括准备、搬运、最后加工工序以及无损检验焊接接头的情况下,才能产生实际效 One of the main development directions of modern welding production is to gradually shift all aspects related to the production of welded components to comprehensive mechanization and automation so as to ensure a substantial increase of labor productivity, improve the working conditions of welders and increase the production efficiency and Quality and reliability. The total work load in the manufacture of welded components, the welding itself only accounts for 15 to 20%. Therefore, comprehensive mechanization and automation can produce practical effects only if both preparation, handling, final processing and NDT weld joints are involved
