Does Laser Welding Galvanized Steel produce a lot of spatter?

Kempson equipment uses Wobble technology to guide zinc vapor discharge. Compared to traditional welding, spatter is reduced by more than 90%, and the weld surface is extremely flat.

Will the anti-corrosion performance of the zinc layer fail after welding?

The heat-affected zone is extremely small, retaining the integrity of the zinc layer around the weld to the greatest extent. Although the zinc layer at the molten pool vaporizes, the overall corrosion resistance is superior to traditional arc welding.

Why choose an air-cooled laser welder for galvanized HVAC ducts?

Air-cooled models (like KPS-Air Cooled) are lightweight, highly mobile, and have no risk of freezing, making them ideal for flexible operations on-site or inside ventilation ducts.

Will porosity occur in GI Sheet Laser Welding Machine operations?

No. By adjusting the waveform frequency and wobble width, zinc vapor can escape completely before the molten pool solidifies, resulting in dense, pore-free industrial welds.

How thick can a 3000W laser welder weld galvanized plate?

The 3000W high-power model can easily penetrate 5-8mm medium-thick galvanized steel, achieving single-sided welding with double-sided forming.

Does Kempson equipment support automatic wire feeding?

Yes. The entire series is standard with a digital automatic wire feeding system, supporting 0.8-1.6mm wire to effectively fill assembly gaps within 8mm.

Galvanized Steel Laser Welder | Zero Spatter Zinc Coated Steel Welding

Einführung

Galvanized Steel refers to steel coated with a thin layer of zinc for physical shielding and electrochemical protection, increasing corrosion resistance and service life. The durability of galvanized steel has made it a cornerstone of modern industry, widely used in construction panels, HVAC air ducts, automobile body manufacturing, home appliance casings, and transportation facilities.

The boiling point of zinc (approx. 906°C) is much lower than the melting point of steel. During welding, the violent vaporization of the zinc layer easily leads to spatter, porosity, and cracks in the weld. To overcome this challenge, the Galvanized Steel Laser Welder was developed. Through high-energy-density precision control, it completes high-speed, aesthetic, and high-strength connections while protecting the anti-rust properties of the zinc layer, revolutionizing the processing standards for galvanized metal.

Why choose a Fiber Laser Welder for welding galvanized steel?

Traditional arc welding methods often cause severe spatter, porosity, and blackened welds due to zinc vaporization. The Laser Welding Galvanized Steel process uses precision control of high energy density to perfectly solve processing problems brought by the zinc layer while ensuring welding strength.

Suppression of Spatter and Porosity: Through waveform control and Wobble technology, the Galvanized Steel Welding Machine can guide the discharge of zinc vapor, reducing spatter and ensuring the weld interior is dense without pores.
Minimal Thermal Distortion: The heat-affected zone of laser welding is extremely small, preventing thermal deformation of thin galvanized parts and allowing the workpiece to maintain its original, precise geometric dimensions.
Protection of Anti-corrosion Performance: High welding speeds minimize damage to the zinc layer around the weld, retaining the original corrosion resistance of the material and reducing the need for post-welding paint repair.
Weld Aesthetics: The weld is narrow and flat with a bright silver appearance, requiring almost no secondary grinding, which saves the process costs of the Fiber Laser Welder on the assembly line.

Choosing a Handheld Laser Welder for galvanized steel solves the process pain points and is an ideal solution to replace traditional welding machines in modern sheet metal, HVAC, and automotive parts manufacturing.
