Horizontal H Beam Welding Line

Horizontal H Beam Welding Line

The horizontal production line of H-shaped steel adopts horizontal assembly, and two longitudinal seams are welded at the same time. Before the work, only the front part of the H-shaped steel wing and the web are welded, and the assembly and two H-shaped steel can be achieved The welding of strip welds greatly improves production efficiency; secondly, the machine can realize bevel welding with small angle.

1. End assembly: first align, splice and spot weld the ends of the three steel plates.

2. The two welding seams on the front welding unit are welded vertically.

3. After the workpiece is turned 180 degrees, it falls on the roller of the front welding machine.

4. The following two welding seams are welded vertically by the welding unit.

5. After the workpiece is turned 90 degrees, it falls on the roller of the straightener.

6.The straightener corrects the welding deformation of the wing plate.

This line adopts advanced and efficient single-arc double-wire welding production technology, which not only has a fast welding speed but also a good shape, so that flat fillet welding can break through the traditional boat-shaped welding. The production line is a simple process from three steel plates assembled into an H shape and welded twice to correct the production process. No hoisting is required. Auxiliary equipment such as chain reversing machine and conveying roller table are used to basically realize the automation of the production process. Except for cutting and cutting, the sequence of the wing plate after correction needs to be transported by the crane, the whole process does not need The crane is transported by crane, and it is welded twice, which greatly improves the production efficiency and achieves a single shift annual production capacity of about 8,000 tons.

The H-beam steel horizontal production line Lemar produced is easy to operate, has a high degree of automation, and has a small deformation of the workpiece. At the same time, the structure is reasonable, so there is no need to adjust when welding workpieces of different sizes. Due to the use of submerged arc welding, the heat radiation during welding is small, which is less harmful to the operator. It has long service life, stable performance and easy maintenance.
