Product Overview

The Medium Frequency Resistance Seam Welding Machine is designed for continuous welding of metal containers, cylindrical components, stainless steel tanks, filter housings, automotive parts, and industrial sheet metal products requiring airtight and leak-proof weld seams.


Unlike conventional spot welding, seam welding creates a continuous welded joint by using rotating wheel electrodes that apply pressure and electrical current simultaneously. This process produces strong, uniform, and sealed weld seams that are ideal for products requiring liquid-tight or gas-tight performance.


Powered by advanced medium-frequency inverter technology, the machine delivers stable welding current, reduced heat distortion, and excellent seam consistency. It is widely used in the manufacturing of fuel tanks, water tanks, metal drums, mufflers, filter cartridges, battery housings, and stainless steel containers.

Why Choose Resistance Seam Welding?

1、Continuous Leak-Proof Weld Seams

Unlike spot welding, which creates individual weld points, seam welding produces a continuous welded joint that improves sealing performance and structural integrity.

2、Improved Airtight and Watertight Performance

The overlapping weld structure helps prevent leakage and is ideal for products that contain liquids, gases, or pressurized media.

3、High-Speed Production

Continuous welding significantly increases productivity compared with manual welding methods.

4、Consistent Weld Quality

Medium-frequency inverter control ensures stable current output and repeatable welding results throughout long production runs.

5、Reduced Heat Distortion

Precise heat control minimizes deformation of thin sheet metal products and improves overall appearance quality.

Customer Application Case

Workpiece:

Steel Radiator Panels and Oil Heater Radiator Assemblies

Customer Challenge:

The customer manufactures oil-filled electric heater radiators and required continuous, leak-proof welding of radiator panels. Their previous welding process resulted in inconsistent weld seams, occasional oil leakage during pressure testing, and low production efficiency. Manual finishing operations also increased labor costs and production time.

PDKJ Solution:

PDKJ provided an Intermediate Frequency Inverter Rolling Spot Welding Machine equipped with a precision seam welding system and stable medium-frequency inverter power supply. The machine enabled continuous welding of radiator panel joints while maintaining uniform weld quality throughout the entire seam.

Results:

• Achieved continuous and leak-proof weld seams for radiator assemblies
• Improved welding consistency and product reliability
• Reduced leakage defects during pressure testing
• Increased production efficiency through continuous automatic welding
• Minimized post-weld finishing requirements
• Lowered overall manufacturing costs

Customer Benefits


By implementing the PDKJ seam welding solution, the customer successfully improved radiator welding quality, enhanced production capacity, and achieved more reliable sealing performance for oil-filled heating products.
