Laser Welder / Laser Welding Technician – Lithium-Ion Battery Manufacturing
Job Objective
Seeking an experienced Laser Welder with hands-on experience in precision laser welding, preferably within lithium-ion battery, battery pack, energy storage, automotive, electronics, or other high-precision manufacturing environments.
Essential Requirements
- Proven experience operating and setting up laser welding equipment, preferably fiber, Nd:YAG, or similar industrial laser systems.
- Experience welding thin-gauge metals such as nickel, copper, aluminium, stainless steel, or similar materials.
- Experience with precision welding of battery cells, battery tabs, busbars, terminals, battery modules, or battery packs is highly advantageous.
- Ability to set and adjust welding parameters including:
- Laser power
- Pulse duration/frequency
- Welding speed
- Focus/spot size
- Shielding gas
- Beam alignment
- Ability to interpret engineering drawings, welding specifications, work instructions, and quality standards.
- Experience using microscopes, cameras, gauges, or other inspection equipment for precision welding.
- Ability to identify and correct welding defects such as:
- Porosity
- Cracking
- Burn-through
- Incomplete fusion
- Excessive spatter
- Misalignment
- Weak or inconsistent welds
- Experience performing machine setup, tooling changes, calibration, and basic troubleshooting.
- Strong understanding of workplace safety, particularly laser safety and electrical/chemical hazards associated with lithium-ion batteries.
- Good understanding of quality-control procedures and production documentation.
- Ability to work accurately in a high-volume, precision manufacturing environment.
Preferred Experience
Candidates with experience in any of the following should be prioritised:
- Lithium-ion battery manufacturing
- EV battery manufacturing
- Battery module or battery-pack assembly
- Energy-storage systems
- Automotive manufacturing
- Aerospace or medical-device manufacturing
- Electronics manufacturing
- Automated or robotic laser welding
- Laser welding of copper, aluminium, nickel, or dissimilar metals
- Vision-guided welding systems
- PLC-controlled production equipment
- Automated inspection systems
- Weld testing and destructive/non-destructive inspection
Technical Skills
Must have:
- Laser welding equipment operation
- Precision welding
- Machine setup and parameter adjustment
- Weld-quality inspection
- Engineering drawings and specifications
- Production and quality documentation
- Basic mechanical troubleshooting
Advantageous:
- Fiber laser systems
- Robotic laser welding
- CNC/automated welding systems
- Laser welding software
- PLC/HMI operation
- Vision systems
- Battery cell/module welding
- MES/production tracking systems
Candidate Profile
The ideal candidate should be:
- Detail-oriented and highly precise
- Comfortable working with small components and tight tolerances
- Safety-conscious
- Mechanically and technically minded
- Able to troubleshoot equipment and process issues
- Comfortable working under production targets
- Quality-focused with strong attention to consistency
- Able to work independently while collaborating with production, engineering, and quality teams
Education & Experience
- Technical qualification, apprenticeship, or equivalent practical experience in welding, manufacturing, mechatronics, mechanical engineering, or a related field.
- 2–5+ years of industrial welding or laser-welding experience preferred.
- Direct lithium-ion battery experience is highly desirable but should not be mandatory if the candidate has strong precision laser-welding experience.
Ideal Candidate
A strong candidate would be a Laser Welding Technician with 3+ years of industrial laser-welding experience, preferably with direct experience welding lithium-ion battery cells, tabs, busbars, modules, or packs, and who can independently set up equipment, optimise welding parameters, troubleshoot defects, and maintain consistent weld quality in a production environment.
