As galvanized sheet metal continues to play a vital role in industries like automotive, home appliances, and construction, manufacturers are under pressure to improve weld quality, reduce spatter, and maintain high dimensional accuracy. Traditional arc welding often struggles to meet these expectations—especially when dealing with thin sheets or demanding surface coatings.

To address these challenges, Han’s Laser has developed a large-travel 4-axis gantry laser welding machine specifically optimized for galvanized materials. By integrating high beam quality, advanced motion control, and intelligent automation, this system delivers clean, efficient, and highly repeatable welds—without compromising the integrity of zinc coatings.

Key Advantages of the System

1.High-Quality Laser Beam for Cleaner Welds

Equipped with a built-in fiber laser, the system offers excellent beam quality (low M²), resulting in concentrated energy and a minimal heat-affected zone (HAZ). This high energy density allows for rapid localized melting, minimizing heat diffusion to surrounding areas. As a result, zinc vaporization is significantly reduced, lowering the risk of porosity and cracks commonly found in galvanized welding.

2.Optimized for Thin Sheets: High Speed, Low Distortion

Galvanized sheets are typically between 0.5–3mm thick, requiring precise heat input to avoid burn-through and warping. The fiber laser’s fast response and low heat input make it ideal for high-speed welding of thin materials. The result is minimal part deformation and excellent dimensional control—crucial for high-precision applications in automotive body panels and appliance housings.

3.Versatile 4-Axis Motion for Complex Weld Paths

Compared to standard 3-axis platforms, this system includes an A-axis rotational motion, enabling flexible welding at multiple angles. Whether working with flat seams, bevel joints, or circular contours, the machine supports complex 2D trajectories such as lines, arcs, rectangles, and compound curves. The table’s repeatability of ±0.02mm ensures highly accurate weld positioning across the entire work area.

4.User-Friendly Programming and Control

Operators benefit from a simplified visual interface and intuitive programming. Built-in welding libraries offer pre-configured settings for galvanized sheet applications, while users can easily modify or add new welding strategies. This makes process adaptation quick and efficient—ideal for manufacturers handling a variety of product lines.

5.Upgraded Safety Features

To ensure operator safety during high-speed operations, the system includes red laser positioning warnings, dual-hand safety start, emergency stop buttons, and safety light curtains. These measures help prevent accidents and support compliance with modern industrial safety standards.

Application Scenarios: Versatility Across Industries

Thanks to its modular design and exceptional motion control, this laser welding machine is suitable for a wide range of industrial applications that demand high weld quality, minimal heat distortion, and fast production cycles. Key sectors include:

Automotive Manufacturing

Ideal for body-in-white components, chassis parts, and structural reinforcements made from galvanized steel. The laser welder minimizes spatter and eliminates back-side burn-through, ensuring surface integrity and weld strength for safety-critical applications.

Home Appliance Fabrication

From washing machine drums to refrigerator liners, galvanized sheet metal is commonly used in consumer appliances. This system delivers fast, precise welds that reduce post-processing and improve surface appearance.

HVAC and Sheet Metal Enclosures

Enclosures for air conditioning systems, electrical cabinets, and ventilation ducts benefit from the system’s ability to perform continuous, uniform welds over large panels.

Industrial Equipment & Cabinetry

Equipment housings, control panels, and galvanized structural components in industrial automation often require consistent weld aesthetics and robust mechanical properties—both of which are ensured by this high-precision laser welding machine.

Construction & Architectural Metalwork

The system is suitable for decorative and structural metalwork where clean, high-quality seams are essential for both performance and appearance.
