About Guangzhou Centro South Tech

Guangzhou Centro South Tech (广州中南科技) is a manufacturer and exporter of YAG laser welding equipment based in Guangzhou, China. We focus on one thing: reliable laser welding machines for jewelry manufacturing, precious-metal work and light industrial applications.

What we do

• Design and assembly of YAG laser welding systems (from 200 W-class workhorses to application-specific configurations).
• Technical support for gold, silver, platinum, copper and steel welding — including 18K/21K gold jewelry repair and production.
• Spare parts, remote troubleshooting and operator training for our customers overseas.

Why work with us

• We answer technical questions honestly. Tell us your material and application; we recommend the right setup — even when that means a smaller machine.
• Machines are tuned before shipping. Every unit is tested on typical jewelry-grade material before it leaves our workshop.
• Support after the sale. Video guidance, spare-parts supply and remote diagnostics — not just a warranty card.

We export to customers in the Middle East, Southeast Asia and India, and we keep our product range focused so that support stays fast and parts stay in stock.
