Why precision parts choose laser welding
Traditional TIG has high heat input, distortion and coarse spots; laser spot welding has a tiny, controllable spot and minimal heat-affected zone, so thin-wall parts are not blown through or warped. Critical for batteries, sensors and medical devices.
Best-fit parts
Battery tabs and spot welds, sensor housings, stainless/titanium thin sheets, jewellery joints and settings, small hardware. Any weld that is small, thin, heat-sensitive and must look good fits laser spot welding.
Relation to the fiber marker
Marking and welding are both laser processing; many factories use a fiber laser marker for identification and a QCW spot welder for assembly welding, sharing one laser-process mindset and simpler maintenance.
Typical industries
New-energy batteries, 3C electronics, sensors, medical devices, jewellery and watches, hardware. Anywhere small parts must join firmly and neatly, laser spot welding is preferred.
Procurement Q&A
Price depends on the model (UV / fiber / CO₂), power, laser-source brand (Raycus / JPT / IPG) and configuration (galvo, field lens, control software). Zhongyi Laser lists the exact laser-source and galvo models on the quote and in the contract, so the configuration is verifiable and easy to reorder or replace later.
Standard machines ship in 7 days; rush orders in 3–5 days; custom non-standard builds in 15–30 days. Before production we confirm drawings, process and sample results to avoid rework.
18-month warranty on the machine. Core parts like the laser source and galvo are replaceable standard parts with long-term supply, so repairs and swaps are documented.
Yes. Send a sample and we return a real test video within 24 hours and ship the part back. Key models get a 48-hour aging test, so you see the actual result on your own workpiece before deciding.

We have 3+ engineers, 7+ authorised patents and 5000+ units shipped. Standard parts like laser source and galvo are stocked long-term for predictable replenishment.
Common range is 0.1–2mm thin sheet with a small heat-affected zone and controlled distortion; thinner needs pulse and defocus tuning. Send a sample for a real weld test.
Not with a proper process. QCW pulses are short and energy is controllable; engineers tune by thickness and validate critical parts with a sample before production.
Yes. Many customers use a fiber marker for identification and a spot welder for assembly in the same shop — shared process, common spares, lower training and maintenance cost.
