机器压焊使用高压电阻压焊机，机械手自动将横杆横放在均匀排列的扁钢上，通过强大的电焊功率和液压力将横杆压焊入扁钢内，从而可以得到焊点坚固，稳定性和强度极高的高品质钢格板。该焊接工艺受设备和电流电压匹配的影响，一般双杆的焊接比单杆的强度高，该焊接工艺还与原料扁钢的高低有关系，扁钢宽度误差大可能影响焊接强度，使强度不一致；该工艺存在的缺陷是假焊和虚焊，假焊和虚焊容易使横杆剥脱。焊接工艺因设备设备的额定容量，截面较大的重型钢格板无法生产。该焊接工艺的设备额定容量低于800KVA的一般只能做4mm厚度以下的扁钢钢格板，1250KVA的一般能做5~6mm厚度的扁钢钢格板。
The machine uses high pressure resistance pressure welding pressure welding machine, manipulator automatic bar will across the flat are evenly arranged on the strong electric power and hydraulic pressure pressure welding in steel flat bar, which can be solid solder joint quality steel plate, high strength and stability. The welding process is affected by the current and voltage matching equipment, welding rod double than the single pole strength is high, the welding process is low and the raw material between flat steel, flat steel width error may affect the welding strength, the strength is not consistent; the defects existing in this process is the false welding and weld, welding and false easy to weld bar stripping. Because of the rated capacity of equipment and equipment, the heavy steel grid plate with large section can not be produced. The rated capacity of the welding process is less than 800KVA, generally it can only be made of flat steel steel grate below 4mm thickness, and 1250KVA can generally make 5~6mm thickness flat steel grid.
