在金属结构制作安装过程中,型钢的接头量是很大的。过去接头的方法是在接头处加上一块适当长度的背板,然后用电焊将母材与背板焊起来,这样不但浪费了大量的劳力、焊条、钢材,而且焊后变形较大,需要二次调整。同时也增加了结构的重量,实践证明这是一种少慢差费的焊接方法。第四冶金建设公司一公司六连焊接工人遵照毛主席“打
In the production and installation of metal structures, the amount of joints of the steel is very large. In the past, the joint method was to add an appropriate length of back plate to the joint, and then to weld the base material and the back plate by electric welding. This not only wastes a lot of labor, welding rods, and steel, but also has a large deformation after welding. Adjustments. At the same time, the weight of the structure has also been increased. Practice has proved that this is a welding method that is less costly. Fourth Metallurgical Construction Company, a company of six welding workers in line with Chairman Mao
