肉类加工厂的管道是较多的,而钢质管又占多数。进行技术改造、更新、安装、修理都离不开管道的焊接。管道要求焊得平、直、齐,关健在焊缝接头。焊接时,一人手扶着,焊工焊接,常因晃动焊管不易对齐,产生返工现象;有时由于焊接位置、条件所限,焊成的管道仍不够理想。 There are more pipelines in meat processing plants, and steel pipes account for the majority. Technological transformation, renewal, installation, and repair are all inseparable from the welding of pipelines. The pipeline requires welding to be flat, straight, and flush. The key is the weld joint. During welding, one person holds hands and the welder welds, often because the welding pipe is not easy to be aligned, resulting in rework phenomenon; sometimes due to welding position and conditions, the welded pipe is still not ideal.
