Overview

Nd:YAG — 1064 nm

A pulsed Nd:YAG laser delivers short, high-energy pulses through a viewing microscope or CCD, so the operator places tiny spot and seam welds exactly where needed — ideal for mould repair, jewellery, sensors and fine components with almost no heat damage.

FAQ

Common questions

Nd:YAG or fiber laser welding?

Nd:YAG pulsed welders suit precise spot welds, mould repair and jewellery under a microscope. For long seams and higher speed on sheet metal, fiber laser welding is usually better — we can test both on your part.

Can it repair moulds?

Yes — with filler wire it rebuilds worn edges, cracks and corners, which are then machined or polished to size.

Sample first, buy second.

Send your part — we run it on the Nd:YAG and send photos back. Need it customised or integrated into your line? We build that too.
