In fields such as industrial manufacturing, hardware processing, and on-site maintenance, traditional processing workflows require the coordination of multiple specialized machines for welding, weld cleaning, surface cleaning, and cutting. This not only occupies a large amount of workshop space but also leads to a 20%-35% extension in production cycles due to the inconvenience of workpiece handling or equipment movement. However, the 4-in-1 handheld laser welding machine, which integrates four core functions, relies on dual-mode control technology (pulsed/continuous laser) and its portable operation characteristics to achieve full-process processing across multiple scenarios. It has become a key piece of equipment for small and medium-sized enterprises (SMEs) and on-site maintenance teams to improve production efficiency and optimize process quality.

Four Core Functions: Precise, Efficient, and Adaptable to Diverse Scenarios

Flexible and Precise Welding

Equipped with a 1064nm fiber laser, it adopts a handheld design that allows flexible operation without the need for a fixed workstation, adapting to welding requirements of workpieces with different sizes and shapes. The continuous laser mode enables stable penetration welding of various metals such as stainless steel, aluminum alloy, and titanium alloy. The pulsed laser mode precisely controls the heat-affected zone (HAZ) within 0.1-0.5mm, effectively avoiding material deformation. It is particularly suitable for scenarios such as local welding of large workpieces and on-site equipment maintenance. With excellent weld consistency in batch processing, it is widely used in repair welding of new energy vehicle parts, splicing of home appliance casings, and assembly of hardware components.

Weld Cleaning

Using 1064nm pulsed laser technology, it precisely controls the energy density (below the substrate ablation threshold). Handheld operation enables targeted removal of welding slag, oxide scale, and spatter from the weld surface, eliminating the need for mechanical grinding or chemical agents. After cleaning, the weld surface roughness reaches Ra ≤ 1.6μm, directly meeting the cleanliness requirements before painting and assembly. It is suitable for scenarios requiring high weld strength and corrosion resistance, such as local weld repair and cleaning of pressure vessels and on-site weld treatment of pipeline projects.

Eco-Friendly Cleaning

Equipped with a dual-wavelength laser module (1064nm/10.6μm), handheld operation allows flexible cleaning of contaminants in different scenarios: the 10.6μm laser efficiently removes oil stains from metal surfaces; the 1064nm laser precisely cleans rust and oxide films; and the nanosecond pulsed mode enables non-destructive precision cleaning of residual adhesive on molds and pins of electronic components. The entire process produces no wastewater or waste residue, replacing traditional pickling processes and reducing chemical agent usage by over 90%, which aligns with the environmental protection needs of green production and on-site maintenance.

High-Precision Cutting

With a 1064nm fiber laser as the energy source, handheld operation combined with a lightweight auxiliary bracket enables cutting of metal materials with thicknesses ranging from 0.1mm to 12mm. The continuous laser mode is suitable for local cutting of thick plates, while the pulsed laser mode ensures cutting precision for thin plates. It supports straight-line, curved, and special-shaped cutting, with a contour accuracy of ±0.03mm, burr-free cuts, and a perpendicularity of ≥85°. Compared with traditional cutting equipment, it improves material utilization by 15%-20%, making it suitable for scenarios such as on-site modification of sheet metal parts, rapid cutting of advertising signs, and emergency blanking of equipment components.
