Handheld Pulse Laser welding machine for Thin metal Plate Welding No Deformation No Blackening No Marks on Backside!#Pulselaser
The primary differences between handheld laser welders and pulsed laser welders lie in their operating modes, application scenarios, and operational methods. Handheld laser welders typically employ continuous laser output, making them suitable for welding large areas and long seams. They offer flexible operation and can be used directly by hand. In contrast, pulsed laser welders primarily utilize intermittent pulse output, making them ideal for precision welding, thin sheet materials, or heat-sensitive materials. This approach effectively controls heat input and minimizes deformation.
From a technical standpoint, the continuous output mode of handheld laser welders delivers stable energy density, making them suitable for high-speed welding. In contrast, pulsed laser welders achieve finer thermal control by adjusting pulse frequency, width, and energy. In terms of application scenarios, handheld laser welders are predominantly used for large workpieces such as automotive manufacturing and shipbuilding, while pulsed laser welders are commonly employed in precision fields like electronic components and medical devices.
Additionally, handheld laser welders typically feature higher power ratings (e.g., 1000-3000W), making them suitable for thick plate welding; pulse laser welders operate at lower power but deliver high peak power, ideal for micro-welding applications. Operationally, handheld units rely more heavily on manual skill, while pulse systems often integrate automated controls. Both types also differ in cost and maintenance complexity, requiring selection based on specific requirements. We currently stock these products in-store. Our laser welders offer power outputs ranging from 1000 to 3000W, support both continuous and pulsed modes, are compatible with various materials, and boast a service life of up to 10 years.

A New Option for Thick Plate Welding: Breakthroughs with Low-Power Pulsed Lasers In the field of precision manufacturing, laser welding technology is challenging conventional wisdom through process innovation. While thick plate welding was once thought to require high-power equipment, low-power pulsed laser welders have achieved breakthroughs in specific scenarios through technological advancements.
The “thick plate potential” of pulsed lasers stems from three major technological breakthroughs:
- Beam Quality Revolution: Utilizing fiber lasers with annular spot technology (e.g., Xinheng’s 2000W equipment), optimized beam modes achieve 11mm penetration depth in aluminum plates—far surpassing continuous lasers of equivalent power.
- Empowered by Hybrid Processes: Laser-arc hybrid welding technology (as demonstrated in the 20mm ship steel plate case) combines precise thermal control with filler material deposition, achieving single-pass forming with distortion below 0.3mm.
- Intelligent Parameter Regulation: Through a three-stage pulse waveform design (preheating, main welding, slow cooling), thermal input is precisely controlled to prevent burn-through or incomplete fusion issues.
Core Advantages of Low-Power Equipment:
- Reduced Heat-Affected Zone: Intermittent output shrinks the HAZ by over 40% compared to continuous lasers, significantly lowering deformation risks for medical devices and aerospace components.
- Master of Highly Reflective Materials: Blue laser technology (e.g., Keldar solution) achieves 98% energy absorption in copper and aluminum, tripling efficiency and enabling welding of new energy battery modules.
- Dual Excellence in Energy and Cost: A 2000W system can weld 11mm aluminum plates with hourly energy costs below ¥5, delivering over 30% energy savings.
Application Scenarios and Selection Criteria: Material Compatibility: Prioritize low-melting-point materials like aluminum alloys, or improve welding of high-melting-point metals through pretreatment (e.g., controlling deformation of titanium alloy implants within 0.15mm). Industry Focus: Mass-produced applications in new energy batteries, medical devices, and 5G chip packaging. BYD’s Blade Battery production line achieved a 40% efficiency boost. Selection Criteria: Prioritize beam quality (e.g., ±0.3% stability), process databases (e.g., Keldar’s 3000+ parameter sets), and intelligent cloud platform capabilities.
Brief introduction of laser spot welding machine:
Laser spot welding machines are suitable for welding stainless steel, gold, silver, alloys, steel, diamond, and other materials of the same type or dissimilar materials. They are widely used in industries such as mobile phone batteries, sensors, medical devices, craft gifts, watches, electronic components, precision machinery, and communications.
Detailed Introduction to Laser Spot Welding Machines:
Equipment Principle:
Laser spot welding machines utilize pulsed lasers with a wavelength of 1064 mm. After beam expansion, reflection, and focusing, the laser irradiates the surface of the workpiece. Heat from the surface diffuses inward through thermal conduction. By digitally controlling precise parameters such as pulse width, energy, peak power, and repetition rate, the laser melts the workpiece to form a specific molten pool. This achieves laser welding of the workpiece, enabling precision welding unattainable through traditional methods.
Laser spot welding machine application range:
Suitable for welding stainless steel, gold, silver, alloys, steel, diamond, and other similar materials, as well as dissimilar materials. Widely used in industries such as mobile phone batteries, sensors, medical devices, craft gifts, watches, electronic components, precision machinery, and communications.

Compared to traditional welding, low-power pulsed laser seam welding offers advantages such as high power density, concentrated energy, low heat input, narrow welds, and minimal deformation. Furthermore, the laser beam can achieve a very small spot size when focused, enabling precise positioning. These characteristics make laser seam welding more suitable than other welding methods for joining small-sized workpieces. For laser welding of ultra-thin stainless steel materials, the extreme thinness of the material makes vaporization and perforation highly likely. Achieving a continuous weld without burn-through hinges on precise parameter control.
Key parameters affecting laser welding quality include welding current, pulse width, and pulse frequency, with their primary effects as follows:
(1) As current increases, weld width expands, spatter gradually appears during welding, and the weld surface exhibits oxidation with a rough texture.
(2) Weld width also increases with pulse width. Pulse width variation significantly impacts laser welding results on ultra-thin stainless steel sheets. Even minor pulse width increases may cause sample oxidation and burn-through.
(3) As pulse frequency increases, the overlap rate of weld points rises. The weld width initially expands but then stabilizes. Under microscopic examination, the weld surface becomes increasingly smooth and aesthetically pleasing. However, when pulse frequency exceeds a certain threshold, severe spattering occurs during welding, resulting in a coarse weld surface and oxidation on both upper and lower surfaces of the welded components.
(4) For laser welding of ultra-thin sheet materials, positive defocusing is recommended. Under identical defocusing conditions, welds produced with positive defocusing exhibit smoother and more aesthetically pleasing surfaces compared to those with negative defocusing.
