Dual-Station Laser Galvanometer Welding Machine for Computer Chassis Enclosures

For a manufacturer serving the new energy sector, welding computer chassis enclosures was never a question of whether the material could be welded - it was whether the process could keep up with batch production. PDKJ answered with a customized dual-station laser galvanometer welding machine: dedicated positioning fixtures for the chassis, programmed galvanometer laser welding, and two stations working in rhythm with the operator. The machine has completed manufacturing, debugging and delivery, and is now producing in the customer's workshop.

Application Overview

Customer Welding Requirements

Customer Background

The customer is a manufacturer serving the new energy field and industrial applications, with a product portfolio that involves large volumes of chassis, box bodies and other sheet-metal structures. Enclosure welding is a recurring operation across the product range, not a one-time job.

Project Background

Welding on these chassis products involves several fixed positions and weld points. As orders and output grew, relying entirely on manual welding raised hard questions about consistency, efficiency and staffing. The customer's request was clear: design an automated welding machine matched to the existing chassis products and built for batch production. PDKJ reviewed the part structure, the weld positions and the on-site production style, and the solution landed on a dual-station laser galvanometer welding machine.

Pain Points and Problems

The core issue was not weldability but production fit. Three characteristics of the product shaped the design:

• Fixed, repetitive weld positions. Chassis enclosures are typical sheet-metal products: every part in the batch needs the same or very similar welds. Repeating those welds by hand means repetitive operations - exactly the work that should be mechanized and built into a machine flow.
• Positioning and welding must stay stable. If the part sits in a slightly different place each cycle, the weld positions move with it. Rather than an operator guiding the welding, the solution pairs dedicated positioning fixtures with the laser process: the part is located and clamped first, then welded.
• A single station is hostage to the loading rhythm. With one welding station, the operator waits for the weld to finish before unloading, reloading and positioning the next part. In batch production, the hand-off between loading and welding decides the output.

The Dual-Station Laser Galvanometer Welding Machine

The machine pairs two workstations with laser galvanometer welding and dedicated tooling, all optimized for chassis sheet-metal welding. The operating flow is deliberately simple:

Manual load -> Fixture clamps the part -> Laser galvanometer welds automatically -> Manual unload -> Next part enters the second station

The dual-station laser galvanometer welding machine with guarding, operator panel and workstations.

1. Two stations, one continuous rhythm. After workstation 1 is welded, the machine switches to workstation 2. While one part is being welded, the operator unloads and reloads the other station, so welding and handling overlap instead of waiting for each other - the structure batch enclosure production needs.

2. Dedicated fixtures take over positioning. For automated welding of a fixed product, tooling decides stability. The machine uses dedicated positioning fixtures with quick clamping, so every part is placed and fixed to the set position - a far better fit for repetitive batch work than finding the position by hand each time.

The operator loading an enclosure into the clamping fixture at the welding station.

1. Laser galvanometer welding built into the machine flow. The galvanometer head executes the programmed weld paths for each product automatically. For fixed products with fixed weld positions, the welding motion becomes part of the machine sequence, keeping the operator out of the weld itself.

2. Guarding that suits equipment-scale production. The welding area is enclosed by aluminum profile guarding, forming an independent working envelope around the process and giving the machine the form of a production device rather than a bench setup.

How the Machine Solves the Customer's Pain Points

1. Repetitive welds move from hands to program. Fixed positions and repetitive welds are executed by the machine, so consistency no longer depends on operator attention across a long shift.

2. Positioning is fixed by the fixture. Dedicated tooling removes per-cycle placement variation, so the programmed weld paths land where they were designed to.

3. Loading no longer stalls welding. The dual-station structure lets the operator service one station while the other welds, smoothing the cycle for continuous batch output.

4. Welding stays inside an enclosed cell. Guarding separates the laser process from the surrounding workshop for safer equipment-style operation.

Why Choose a Dual-Station Design?

Automation does not mean removing people from the process entirely. In this project, the machine takes over what it does best - repeatable, programmed welding - while the operator handles loading and unloading. The dual-station layout is what makes that division efficient: the operator works one station ahead of the machine, and neither waits for the other.

Key Advantages

• Dual-station layout with dedicated positioning fixtures and quick clamping.
• Programmed laser galvanometer welding for fixed weld positions.
• Manual load / automatic weld / manual unload cycle designed for batch production.
• Aluminum profile guarding enclosing the welding area.
• Process, tooling and guarding matched to chassis sheet-metal welding.

Potential Applications

The same structure fits any fixed-geometry sheet product welded at volume: electrical cabinets, inverter and control enclosures, battery boxes, server chassis and other box-type sheet-metal parts with repeating weld patterns.
