Which industries can laser welding machines be used for?

Laser welding isn’t just a high-tech buzzword anymore. It’s solving real-world problems—from EV battery assembly to complex aerospace components.

Laser welding machines are now core equipment in industries where precision, strength, and cleanliness are critical—like automotive, aerospace, and medical manufacturing.

I’ve seen firsthand how switching to fiber laser welding cut failure rates and boosted output for manufacturers under pressure. The level of control and quality it offers makes it more than just a welding upgrade—it’s a production game changer.

What industries use laser welding?

When I think about how widespread laser welding has become, I always go back to the basics: any industry that values clean, strong welds and low heat input can benefit. But certain sectors stand out.

Industries like automotive, aerospace, medical, energy, and electronics are leading adopters, thanks to the specific advantages laser welding provides in terms of strength, precision, and reduced post-processing.

Industry-by-Industry Breakdown

Industry	Typical Components	Pain Points Solved by Laser Welding	Welding Specs Required
Automotive	Battery tabs, chassis parts, sensors	Weld strength, automation, speed	1.5–3kW, deep seam + spot
Aerospace	Fuel lines, aluminum skin, turbine blades	Low-distortion welding, alloy compatibility	2–3kW, thin-gauge precision1
Medical	Implants, surgical tools, batteries	Bio-compatibility, micro-welding	1.5kW, ultra-low HAZ
Electronics	Contacts, sensors, wire connectors	Precision, no contamination	1.5–2kW, pulse welding
Energy	Fuel cells, power units, battery housings	Tight sealing, clean welds, fast cycle times	2–3kW, overlap + deep welds

One of our clients in the EV industry told us plainly: "We didn’t just want better welds—we needed them to scale. Laser welding² gave us both."

What is a laser welding machine used for?

Laser welding machines³ aren’t just used to stick metal pieces together. They are tools of transformation in modern manufacturing lines.

Laser welding machines are used to join metals with high precision, delivering repeatable, low-heat, spatter-free welds that reduce cleanup and rework.

Core Functional Capabilities

Here’s what a fiber laser welding machine like ours at Kirin Laser typically does:

1. Deep Penetration Welding⁴

Used to achieve high-strength welds in thick or structural metals. Minimal surface opening, high core strength.

2. Fine Spot Welding

Essential for micro-assemblies like battery tabs or electronics connectors. Ultra-low energy, high precision.

3. Seam Welding

Continuous welding along joints for aesthetic or pressure-sealed components (e.g., stainless pipes or medical enclosures).

4. Dissimilar Metal Welding⁵

Joining aluminum to copper, steel to nickel, etc. Works well where traditional welding fails.

Power Level	Material Type	Max Thickness (mm)	Common Uses
1.5kW	SS / CS / Aluminum	5 / 4 / 4	Batteries, frames, thin pipes
2kW	SS / CS / Aluminum	6 / 5 / 5	Machinery housings, medium-size parts
3kW	SS / CS / Aluminum	8 / 8 / 6	Structural beams, tank fabrication, load-bearing welds

I personally love how versatile the machines are. With just a nozzle change and a power tweak, you can move from micro-sensor welding to a thick carbon steel frame.

What are the applications of laser welding?

Laser welding's applications are far more diverse than people expect. We’ve supported clients from jewelry designers to defense contractors.

Laser welding is applied in cleanroom-level tasks and heavy-duty operations alike, due to its ability to scale precision, depth, and speed across applications.

Laser Welding Application Categories and Use Cases

Micro and Precision Welding⁶

Used in: electronics, medical tools, optical parts
Why it matters: avoids heat deformation, highly accurate joints
Real-world example: dental scalers, pacemaker shells

Seam Welding

Used in: EV battery packs, automotive frames
Why it matters: air-tightness, speed, visual quality
Real-world example: lithium battery tab-to-can welding

Spot Welding

Used in: bracket attachment, micro-sensors
Why it matters: discrete joints, minimal distortion
Real-world example: smartphone frame assemblies

Hybrid Welding (with Filler)⁷

Used in: heavy-duty parts where gap bridging is needed
Why it matters: Combines laser precision with filler flexibility
Real-world example: steel pipe production in oil & gas

Application Type	Industry	Equipment Spec Example	Key Advantage
Precision Micro-Welding	Medical, Jewelry, PCB	1.5kW, Pulse Mode	No rework, ultra-low HAZ
Seam Welding8	Automotive, EV, Aerospace	2kW, Continuous Wave	High-speed, continuous seam
Deep Spot Welding	Energy, Heavy Equip	3kW, CW + Oscillation	Structural strength
Filler-Based Hybrid	Construction, Oil & Gas	3kW + Wire Feeder	Bridges gaps, stronger welds

Kirin Laser offers modular accessories so clients can easily switch between these modes, depending on the project. That flexibility often saves thousands in equipment downtime.
