Compare laser welding machines for handheld operation, precision workstations, automated production and robotic integration. The current range includes fiber, QCW and YAG platforms for steel and stainless steel, aluminum alloys, copper alloys, titanium alloys, nickel-based and high-temperature alloys, battery materials and metal foils.
How to choose a laser welding system
Start with material and thickness, joint design and fit-up, required penetration and appearance, allowable heat input and distortion, shielding method and target cycle time. The power figures below describe the current product range; they are not universal safe limits for every material or thickness. Final configuration requires sample validation.
| System route | Current product range | Selection boundary |
|---|
| Handheld fiber laser welding | 1000–3000 W | For accessible joints, flexible changeovers and high-mix fabrication; confirm material, thickness, gap and penetration with actual parts. |
| Precision QCW, YAG and fiber welding | Platform-specific | For small parts, localized repair and work requiring controlled heat input; power alone does not predict the result. |
| Automatic welding / robotic welding | Integrated to tooling and takt time | For repeatable paths and stable production; evaluate fixtures, motion, vision, shielding and quality monitoring together. |
| Mold repair laser welding | Evaluated by defect and base material | For localized build-up and dimensional recovery; filler, preparation and finishing depend on the repair target. |
Process boundaries to confirm first
- Highly reflective or conductive materials such as aluminum and copper, dissimilar metals, thin foils and cosmetic surfaces should not use generic settings without validation.
- Power is only one variable; spot size, pulsed or continuous output, speed, focus, wire feed, shielding and fit-up consistency all affect the weld.
- Handheld systems prioritize flexibility, while automatic and robotic systems prioritize repeatability, takt time, traceability and line interfaces.
- Weldable thickness, penetration, strength, porosity and distortion must be confirmed from the material certificate, joint drawing and actual sample results.
From sample welding to system configuration
Review the laser welding process guide, then use sample testing and process validation to submit material, thickness, joint drawings, target cycle time and acceptance criteria. For equipment or automation planning, request a sample weld and configuration review.
Frequently asked questions
How do I choose between handheld, precision and automated laser welding?
Start with handheld equipment for frequent changeovers and accessible joints, precision platforms for small parts, localized repair or controlled heat input, and automatic or robotic systems for fixed paths, stable takt time and traceability.
Does higher laser power always produce a better weld?
No. Power must match material absorption, thickness, joint design, travel speed, spot size, focus and shielding. Excessive heat input can increase distortion, spatter or metallurgical risk.
Can aluminum, copper and dissimilar metals be laser welded?
They can be evaluated, but reflectivity, thermal conductivity, oxide layers and metallurgical compatibility change the process window. Use sample welding to confirm strength, appearance and stability.
What information should I prepare before requesting a quote?
Provide material grade, thickness, joint and gap, drawings or photos, required penetration and appearance, target cycle time, current defects and acceptance method.
Why is sample welding required before production?
Sample validation confirms the parameter window, fixture and fit-up requirements, shielding method, quality metrics and cycle time before equipment is selected from catalog power alone.
