Custom Handheld Fiber Laser Welding Machine with Automatic Wire Feeder (All-in-One)

Presentation of the equipment's characteristics

The Greenstone GST Series Handheld Fiber Laser Welding Machine with Automatic Wire Feeder is an all-in-one portable laser welding solution that integrates the fiber laser source, cooling unit, and intelligent control system in a compact cabinet for easy movement and fast deployment. Designed for modern fabrication and light-to-medium industrial production, it supports wobble welding head + automatic wire feeding to achieve smooth, consistent weld seams with minimal deformation.

The GST handheld laser welder is widely used for stainless steel, carbon steel, galvanized sheet, and common metal fabrication, offering reliable performance for butt welds, fillet welds, lap welds, edge welds, internal/external corner welds and irregular joints. With a clean weld appearance and reduced post-grinding needs, it helps manufacturers improve productivity while lowering total welding cost.

All-in-One Integrated Design: Laser source + chiller + control integrated into one cabinet, saving floor space and enabling quick site relocation.
Automatic Wire Feeding for Better Gap Bridging: Supports multiple wire diameters, improving fill capability and weld stability on joints with gaps or varying fit-up.
High-Quality Weld Appearance: Smooth seam, low heat input, low deformation, and reduced spatter—often minimizing or eliminating post-polishing.
Multi-Process Capability: Suitable for a broad range of weld types (butt/lap/corner/fillet/irregular), meeting diverse job-shop and production needs.
Fast Learning Curve & Lower Labor Cost: User-friendly operation helps shorten training time, ideal for factories facing skilled welder shortages.
Industrial Safety & Reliability: Built for continuous operation with dedicated protection functions to support safer and more stable welding in real workshops.
