4000W Air Handheld Laser Welding Machine: Utilizes self-generated high-purity inert shielding gas to reduce gas costs, suitable for medium-to-high power welding of metal plates ranging from 0.5 to 12 mm thick.
3000W/4000W Water-Cooled Handheld Laser Welding Machine: Equipped with a water-cooling system ideal for extended, high-intensity welding operations, suitable for large-scale production.
This high-power integrated air-cooled handheld laser welding machine is designed for efficient welding from thin sheets to thick plates without the need for external shielding gas. Featuring a built-in high-purity inert gas generation system, it eliminates bottled gas consumption while enabling stable welding of 0.5–12mm carbon steel, stainless steel, and aluminum plates.
The Water-Cooled Handheld Laser Welding Machine is tailored for high-load production in fixed workstations. Its efficient water circulation enables 24/7 operation, making it ideal for standardized environments with fixed cycles and continuous production. Suitable for batch production and automated welding stations in machinery manufacturing, sheet metal fabrication, metal doors/windows, and guardrail processing.
Our Nitrogen Generator is an optional accessory for handheld laser welding, providing on-demand high-purity nitrogen to improve weld quality and reduce oxidation. It delivers up to 99.99% purity, with flexible settings from 99.5%–99.99%, ideal for stainless steel, aluminum, and precision welding. Backed by a 3-year warranty and after-sales support in 22+ countries, it is offered at true factory-direct price with zero markup, giving you full freedom to choose.

To choose the right handheld laser welding machine for thick plates, focus on laser power, plate thickness range, cooling method, and wire feeding system. For materials above 6 mm, a 3000–4000W high-power machine is recommended. Air-cooled systems suit flexible and cost-sensitive applications, while water-cooled systems are better for long-duty industrial welding. Matching the machine to your material type and production intensity is critical for stable results.
Single wire feeding is suitable for standard joints and general thick plate welding.
Dual or multi-wire feeding is recommended when wider weld seams, higher filling volume, or reinforced weld buildup is required. For thick plates, dual or triple wire feeding improves weld fullness, strength, and appearance, especially for gap-bridging or build-up welding applications.
A typical workflow includes parameter setting → material preparation → wire feeding adjustment → welding execution → weld inspection. Operators only need basic training thanks to the intuitive touchscreen interface. Compared with traditional welding, laser welding requires less preheating, produces minimal spatter, and significantly reduces post-weld grinding.
Thick plate handheld laser welding machines can weld stainless steel, carbon steel, aluminum, copper, titanium, and various alloys. With proper power selection and shielding, they are suitable for both thin sheets and thick plates up to 10–12 mm, depending on material type and joint design.
Handheld laser welding supports multiple methods, including butt welding, fillet welding, lap welding, corner welding, and build-up welding. High-power systems also enable single-side welding with double-side forming, making them ideal for structural and load-bearing applications.
Kempson handheld laser welding machines come with a 3-year warranty on the complete system. In addition, we provide free sample welding tests, remote technical support, and lifetime after-sales service, supported by service networks in 22+ countries worldwide.
