Automatic Laser Stud Welder

Stud welding is widely used in sheet metal fabrication, automotive components, electrical enclosures, and various structural parts manufacturing. However, in real production, stud welding is not a standardized process. Different products require different machine configurations, mainly depending on:

Stud size and type

Material (carbon steel, stainless steel, aluminum, etc.)

Welding position (flat, vertical, inclined, curved surfaces)

Production volume and automation requirements

Based on these practical needs, we have developed the Automatic Laser Stud Welder, a flexible platform integrating laser welding technology, CNC motion control, and customizable fixture systems, capable of adapting to various stud welding applications.

What Does This Machine Actually Provide?

This is not just a stud welder. It is a modular automated welding platform that enables:

Automatic positioning of welding points

Adaptation to different workpiece geometries

Support for multiple welding methods

Consistent welding quality in batch production

Core System Configuration

1.Laser Welding System

The machine is equipped with a fiber laser source, configurable according to different applications:

Power range: 1000W – 3000W

Welding modes:

Pulsed laser welding (high precision, low heat input)

Continuous laser welding (deeper penetration, higher efficiency)

The specific parameters depend on material type, thickness, and stud size. It is recommended to consult us for selecting the most suitable configuration.

2.Stud Welding Head

The stud welding head can be configured based on different working conditions:

Fixed welding head

Adjustable angle mounting

Optional additional motion axis (for complex angles)

Different configurations correspond to different welding scenarios:

Welding studs on flat surfaces: the welding head can be mounted vertically with an XYZ motion system, and no angle adjustment is required.

Welding on inclined surfaces: an angled welding head or additional motion axis is required.

Welding on curved surfaces: an AB rotation axis can be added to the welding head, combined with a rotary fixture system.

3.CNC Motion System (XYZ Axes)

Standard configuration includes:

XYZ three-axis servo motion system

Positioning accuracy: ±0.05 mm

High repeatability, suitable for batch production

This enables:

Multi-point stud welding

Complex welding paths

Automatic positioning without manual alignment

4.Rotary Fixture System (Optional)

For special product structures, a rotary fixture can be added. Different clamping ranges and motion methods can be selected based on the product.

It is especially suitable for:

Curved welding paths

Cylindrical or symmetrical structures

Continuous welding requirements

Advantages of rotary fixtures:

Smooth welding trajectory

Improved efficiency

Better welding consistency

Welding Solutions for Different Applications (ZS Laser)

Solution 1: Moving Welding Head (Standard Solution)

Suitable for:

Flat sheet metal parts

Multi-point welding layouts

Irregular welding positions

Process:

Place studs on the workpiece

CNC controls the movement of the welding head

Welding is completed point by point,as shown in the video below:

Solution 2: Fixed Welding Head + Rotary Fixture

Suitable for:

Curved welding

Symmetrical structures

High-efficiency batch production

Process:

Welding head remains fixed (vertical or angled)

Workpiece is mounted on a rotary fixture

Continuous or circular welding is completed through rotation.

Solution 3: Multi-Axis System

Suitable for:

Inclined surface welding

Complex 3D structures

Non-standard workpieces

Configuration features:

Additional motion axis on the welding head (left-right or front-back swing)

Combined with rotary fixture system

This configuration is not limited to stud welding; it can also be used for welding various small metal components.

How to Choose the Right Configuration

The machine configuration must be determined based on your product.

1.If your product has many welding points and a relatively regular structure, and only simple curved welding is required, you can choose a standard XYZ motion system.

2.If your application requires welding studs onto curved surfaces or the product is symmetrical, a rotary fixture system is recommended.

3.If the welding angle is not vertical, the structure is complex, or higher precision is required, a multi-axis system is recommended.

The fastest approach is to provide us with your product details, and our engineers will recommend the most suitable configuration.

Materials and Industries Applications

The machine supports a wide range of materials:

Carbon steel

Stainless steel

Aluminum alloys

Copper

Galvanized materials

Note:

For highly reflective materials such as copper, sample testing is recommended to determine optimal parameters.

For galvanized materials, spatter may occur; this can usually be managed by increasing shielding gas flow and optimizing parameters.

Typical Applications

Electrical cabinets and enclosures

Stud welding is used for mounting internal components and grounding points. Typically, M4–M8 studs are welded inside cabinets to fix breakers, relays, terminal blocks, and power modules. Thin sheet materials (1–3 mm) with many welding points require high consistency, making automated systems ideal.

Automotive sheet metal parts

Used for mounting brackets, sensor points, wiring harness supports, and battery pack structures. These applications require fast cycle times, high strength, and consistent quality, often combined with automation or robotic systems.

Metal housings and sheet metal structures

Used for internal mounting of PCBs, brackets, and rails. Compared to drilling and tapping, it preserves surface integrity, making it ideal for coated or anodized products.

Structural brackets and load-bearing components

Used for mounting points and structural connections. Typically involves thicker materials (>3 mm) and larger studs (M8–M12), requiring higher strength.

Industrial equipment enclosures

Used for fixing covers, panels, and functional modules. Requires long-term stability and consistent quality in batch production.

HVAC systems (ducting and insulation)

Used for welding insulation pins onto ducts. Requires high speed, stable adhesion, and no burn-through of thin materials.

Shipbuilding and offshore engineering

Used for cable supports, pipe mounts, and internal structures. Requires high reliability in harsh environments (humidity, vibration).

Steel structures (shear studs)

Used in bridges and composite structures to improve bonding between steel and concrete. Requires high power and strong welding performance.

Home appliances and stainless steel products

Used for hidden fastening in kitchen equipment, ovens, and appliances, improving appearance and assembly efficiency.

New energy and battery systems

Used in battery housings, energy storage systems, and photovoltaic structures, requiring lightweight design and automation.

Machinery and automation equipment

Used for mounting rails, sensors, and structural supports, often integrated into automated production lines.

Advantages of the Automatic Laser Stud Welder
