Multi-Spot Welding Machine for Refrigerator Shells

Multi-Spot Welding Machine for Refrigerator Shells: an efficient integrated solution for welding Refrigerator Shells

In the manufacturing of refrigerators, the quality of shell Welding directly affects the structural stability and appearance. The Multi-Spot welding Machine for Refrigerator Shells, with the advantage of multi-point spot welding, has become a key production equipment. It can complete the welding of multiple connection points at one time, taking into account both efficiency and precision. It forms a collaborative system with other welding machines to meet the manufacturing requirements of refrigerator shells. ​

As the core of the industrialization of home appliances, the Machine reshapes the production rhythm through integration. The outer shell of the refrigerator is made by stamping thin steel plates, and dense welding points need to be formed at the edges and corners. It completes the welding of one area within 1-2 seconds through the synchronous action of multiple sets of electrodes, processing thousands of shells daily, significantly shortening the production cycle. ​

Compared with the Friction Welding Machine, it is more suitable for thin-walled steel plates. Friction welding machines are suitable for thick-walled components and are prone to causing deformation of thin steel plates. The multi-point welding machine achieves heat welding through local resistance, with a small heat-affected zone, ensuring that the surface flatness error is ≤0.5mm, meeting the appearance requirements. ​

The Spot Welding Machine is the basic equipment, but this equipment achieves a leap in efficiency. Traditional spot welding machines only have one welding point at a time, which is prone to positioning errors. The multi-point welding machine can weld 4 to 8 points at one time, with a spacing error within ±0.2mm. Its efficiency is increased by 3 to 5 times, making it suitable for the demand of dense welding points. ​

When dealing with the Butt Welding of long straight edges, the Butt Welding Machine is prone to generating weld spurs that affect the appearance. This equipment achieves multi-point welding at the edges, with evenly distributed weld points, ensuring strength and reducing processing steps, meeting the requirements of lean production. ​

The Seam Welding Machine is used for inner liner sealing, while this equipment focuses on the fixation of the outer shell structure. Discrete solder joints meet the strength requirements (shear resistance of a single solder joint ≥5kN), reduce thermal effects, prevent discoloration and deformation of the shell, and ensure a consistent appearance after spraying. ​

The Laser Welding Machine for Steel Ring is suitable for the annular components around the compressor. This equipment has a significant cost advantage in large-area welding, with a cost performance 2 to 3 times that of the Laser Welding Machine, and is suitable for batch production. ​

Stud Welding Machine fixes hinges and other accessories, complementing this equipment. The stud welding machine ensures the smooth opening and closing of the door body, and the multi-point welding machine completes the shell splicing, jointly guaranteeing the stability and integrity of the refrigerator. ​

In conclusion, the Multi-Spot Welding Machine for Refrigerator Shells precisely meets the requirements of Refrigerator Shells, works in coordination with various welding machines, covers multiple links, and provides guarantees for the quality of refrigerators and the competitiveness of enterprises.
