Product Details

Features of roll welding machine

1. The surface of the roller electrode is easy to adhere and the surface quality of the weld is deteriorated. Therefore, the trimming of the electrode is a particularly noteworthy problem.

2. Roll welding consists of a part of overlapping joints. Therefore, the shunt during welding is much more severe than spot welding, which makes it difficult to weld highly conductive aluminum alloys and magnesium alloys.

3. The welding and thermomechanical (force) spot welding processes are the same. In contrast, the mechanical (force) effect in the welding process is insufficient (except for step seam welding). The faster the welding speed, the more obvious the performance.

4. Since the cross-sectional area of seam welding usually exceeds twice the vertical load area of the base metal (the thinner the plate, the larger the proportion), the influence of heat must occur. Base metal area. Therefore, the weld structure rarely emphasizes joint strength, and mainly requires good sealing and corrosion resistance.

Structural principle

The welding mainframe of the Guangdong roll welding machine adopts a cantilever structure. The two cantilever beams are annealed after stress treatment to ensure that the beams will not deform for a long time;

Pneumatic button-type pressing structure is closely arranged along both sides of the straight seam to ensure that the butt weld is uniformly compressed throughout the entire welding length; the distance between the left and right buttons can be adjusted to suit the welding of different workpieces

Depending on the thickness of the workpiece, a bladder or a cylinder can be used to ensure sufficient pressure to prevent thermal deformation during the welding process;

Copper mandrel is inlaid on the welding mandrel to provide welding back-gas protection; different welding process slots are processed according to cylindrical or flat workpieces to achieve single-sided welding and double-sided molding.

The welding mandrel and key press fingers can be adjusted to meet the welding requirements of different workpieces.

The welding torch is driven by a DC servo motor, rack drive, track surface grinding, stable walking, stable and reliable welding.

All air hoses and cables are placed in the energy chain, neat, while avoiding cable breaks.
