CHUNG SONG INDUSTRY (KOWELD Brand) – SOUTH KOREA’S LEADING CREATOR OF AUTOMATIC WELDING SOLUTIONS
Located in the industrial city of Gimhae (Gyeongnam, South Korea), CHUNG SONG INDUSTRY CO., LTD is proud to be one of the world’s leading manufacturers of mechanical equipment and automatic welding systems under the renowned brand KOWELD.
With the mission “Automating every weld”, KOWELD has been providing superior welding carriage solutions, helping heavy industry enterprises completely solve the problems of productivity, labor shortage, and standardizing weld quality.
KOWELD’S OUTSTANDING TECHNOLOGICAL DNA
The difference that makes KOWELD’s name in the international market lies in the core technological foundation applied consistently across its product ranges:
- Brushless DC Motor (BLDC Motor): All KOWELD welding carriage systems are equipped with 24V BLDC motors (5000 RPM). This provides ultra-smooth operation, absolutely uniform speed, and durable lifespan in harsh construction site environments.
- Pioneering Wireless Technology: KOWELD is one of the few brands offering the option of BOSCH Lithium-ion 18V 4.0Ah Battery (“B” code product line). This design turns the welding carriage into a perfect mobile machine, completely eliminating the entanglement and risks from power cables.
- Super strong magnetic traction: With a magnetic attraction force of up to 32kg, KOWELD welding carriages can firmly adhere and move safely on all flat surfaces, vertical walls, or even work upside down on ceilings.
- International Safety Standards: KOWELD products pass the strictest inspections, achieving certifications such as CE (Europe) and NRTL / TÜV (North America).
COMPREHENSIVE PRODUCT ECOSYSTEM
Whether customers are constructing pressure vessels, assembling ship hulls, or manufacturing shaped steel beams, KOWELD has specialized designs:
- Fillet Welding Carriage Series: Free-running with magnetic wheels. Supports 1-torch welding (CS-71, CS-51) or 2-torch simultaneous welding (CS-71B, CS-51B), integrated with automatic stitch welding and crater filling features (CS-251).
- Wall Traveling Series: Experts in adhering to fin walls, T-beams, and L-beams to weld horizontally (CS-41, CS-41S).
- Railless Weaving Series: Creates deep-penetration fish-scale weld beads without wasting time installing guide rails (CS-61WE, CS-51WE).
- Rail Traveling Series: Moves via an absolutely precise rack-and-pinion mechanism. Integrates smart LCD control screens, applicable for Submerged Arc Welding (SAW) or Vertical-Up welding (V-UP).
- Rail Pipe Welding System: Smart ring rail design (from 500Ø to 2000Ø) wrapping around the pipe body, the perfect solution for wind tower columns and pipelines.
- Electro Gas Welding (E.G.W) System: Heavy-duty machines specialized in welding super-thick ship hull steel plates with ultra-high productivity.
