随着大型发电机组的发展。我厂生产的焊接结构尺寸渐趋增大,钢板厚度也在不断增加,并且大量的采用了普通低合金钢制造焊接结构,焊接工作量甚大,手工电弧焊已经不能满足生产发展的需要。又因焊缝形状不规整限制了埋弧自动焊的使用范围。埋弧半自动焊由于焊工不易观察焊缝成型,因而也不能收到满意的效果。为此迫切需要采用效率高、质量好、适应
With the development of large generating units. The size of welding structure produced by our factory is gradually increasing, the thickness of steel plate is also increasing, and a large number of ordinary low alloy steel welding structures are used. The welding workload is very large, and manual arc welding can no longer meet the needs of production development. And because of the irregular shape of the weld submerged arc welding limits the scope of use. Submerged arc semi-automatic welding Welder is not easy to observe the formation of the weld, which can not receive satisfactory results. Therefore, it is urgent to adopt high efficiency, good quality and adaptability
