The production line has the following characteristics:
1. At the end of the assembly, only the spot welding at the end of the workpiece (the welding length is about 100 × 150mm, and the full length spot welding of the workpiece is not needed) can be entered into the next welding process. The welding machine can weld three "bulk plates" after positioning, so that the efficiency of the assembly can be greatly improved.
2。 The welding mode of horizontal placement of workpiece (horizontal web of H steel, vertical flange plate), fixed movement of workpiece by welding torch, and two welds at both ends of H-beam are welded at the same time, which reduces the distortion and deformation of workpiece caused by welding heating.
3. Configure Lincoln welding power supply, realize single arc double wire welding, use 1.6mm fine welding wire, welding speed can reach 1.9m / min, weld molding is good, appearance is beautiful.
4. Because the automation degree of the production line is higher than that of the traditional production line, the labor intensity of workers can be reduced, operators are reduced, and only 2-3 operators are required to be produced normally.
5. The production of the variable-section H-shaped steel with the temperature of 15 DEG can be adjusted.
