Dalian Sanjun Heavy Industry Co., Ltd. is a small enterprise specializing in manufacturing stainless steel components. The company faced several challenges using traditional welding equipment, including high labor costs for manual grinding (approximately 120 CNY/month), high material costs (about 50 CNY/month), and low welding efficiency. Each welding piece took an average of 45 minutes to complete, and the effective daily work hours were limited to just 6 hours, severely affecting the company’s ability to meet order deadlines. Therefore, they consulted Kempson for a solution using a handheld laser welding machine for stainless steel.

Thin Sheet Water-Cooled Handheld Laser Welding Machine for Stainless Steel​

Custom Requirements

Dalian Sanjun Heavy Industry requires a welding solution with the following requirements:

  • Increase welding speed to enhance production efficiency and ensure timely delivery.
  • Reduce labor and material costs by eliminating manual grinding and minimizing consumable expenses.
  • Improve welding quality to ensure smooth, stable, and uniform welds.
  • Provide user-friendly equipment with minimal training requirements capable of sustained continuous operation.

Solution

Kempson’s team recommended the KPS-LHW1500 water-cooled handheld laser welding machine for stainless steel, which was perfectly suited to the customer’s needs. The solution included:

1500W Power: Ideal for welding stainless steel up to 2.5mm in thickness with precision.

Water-Cooled System: Equipped with a 4.2kW copper tube cooling system, ensuring stable and continuous operation for 24-hour shifts.

Black Gold Welding Gun: Patent-protected technology for high-quality welds, reducing post-weld work.

Accurate 4WD Wire Feeding System: Ensures smooth, precise wire feeding without clogging or sticking, reducing downtime.

Low Consumables Cost: Monthly consumables cost is only 150 CNY, significantly lower than traditional methods.

Easy Operation: The system features an intuitive interface with parameter storage, allowing for minimal training and ease of use.

In October 2025, the Kempson team conducted an on-site survey, demonstrated the stainless steel welding effect, and completed the contract delivery, providing operation training and 24-hour after-sales support.

Customer Feedback

After putting the equipment into operation, the customer reported a significant boost in production efficiency. Welding tasks that previously required substantial manual labor have become considerably easier. With improved weld quality, rework and returns have decreased substantially, and issues encountered during production have been effectively resolved. The customer specifically noted that the welds are not only smooth and aesthetically pleasing but also consistently high in quality. They plan to purchase another 1500W model to support future production expansion.
