Splicing Plates Automation Welding Machine (Plate to Plate)

Summary

Splicing plates welding machine is mainly used for carbon steel, stainless steel, titanium  alloy, aluminum and alloy flat docking. Suitable for tablets between 1.5-8mm flat, in the  case of oblique cutting or milling, the thickness of the effect can reach 12mm. It can be  equipped with TIG, MIG/MAG, PAW, SAW and other welding technology methods, the  welding effect can be shaped up on both inside and outside by only welding on outside  surface. The equipment structure is advanced, the welding process is reliable and effi- cient, and the entire control process is controlled by touch screens and PLC.

1. Suitable for splicing plates welding of thin plates with a thickness of 1.5-12mm;

2. Adopting piano-key compress method, the welding effect is good during heat dissipation, the workpiece deformation is small, and the welding quality is high;

3. Can be shaped up on both inside and outside by only welding on outside surface through  the liner, and the best surface quality can be obtained through the front and back;

 

Plate-to-plate welding machines (also known as splicing plate automation welding machines) are specialized systems designed for joining large metal plates together, often used in industries where precision, efficiency, and high-quality welds are essential. These machines automate the splicing process to ensure consistent weld quality, minimize distortion, and increase productivity.
