4in1 Laser Welding Machine for Spot, Seam, Lap & Butt Welding

A 4 in 1 laser welder is a compact yet powerful device that combines four welding techniques—spot, seam, lap, and butt welding—into a single portable or benchtop system, ideal for small-scale production, repair work, or custom fabrication. Equipped with a fiber laser source ranging from 1kW to 3kW, this welder is suitable for thin to medium metals (0.5mm to 8mm) such as carbon steel, stainless steel, and aluminum. The "4 in 1" functionality allows users to switch between welding modes using interchangeable tips or software adjustments, making it versatile for different applications, from jewelry making to automotive repair. The welder typically features a handheld design for portability or a fixed gantry system for precision, with an intuitive control panel for adjusting parameters like laser power, pulse frequency, and welding speed. An assist gas nozzle delivers shielding gas (argon, nitrogen) to protect the weld pool, while a built-in cooling system prevents overheating during continuous use. This compact solution is cost-effective for small workshops or on-site repairs, as it eliminates the need for multiple welding machines and reduces training requirements. Its ability to perform multiple welding processes in a single unit enhances efficiency and flexibility for users dealing with diverse metalworking tasks.
