国内在细丝二氧化碳气体保护焊方面已有很成熟的经验;而粗丝二氧化碳气体保护焊仅在部分厂的生产上获得了应用。我厂的焊接工作量甚大,而且中厚板较多,最宜应用粗丝二氧化碳气体保护焊。近一年多来进行了一些摸索研究,刚开始时厂内一无设备,二无经验,在这种情况下等待条件具备后再上,还是走自力更生的道路创造条件上。很多同志认为:没有条件自己创,没有经验可从实践中学,因此,就组织力量进行设备改装及焊接工艺试验。 China has very mature experience in the filamentous carbon dioxide gas shielded welding; while the thick carbon dioxide gas shielded welding has been applied in some factories only. I plant a lot of welding workload, and more plates, the most appropriate application of thick carbon dioxide gas shielded welding. In the past year or so, some groping research has been carried out. At the beginning, there was no equipment in the factory and no experience in the factory. In this case, the conditions are met and conditions are afforded to be fulfilled or created on the road of self-reliance. Many comrades think that there is no condition to create their own, and no experience can be learned from practice. Therefore, equipment modification and welding process tests are conducted on the organizational strength.
