Stainless steel, carbon steel and galvanized steel, plus aluminum. Copper and brass are supported at 3 kW.
The low heat input also makes the process practical in places conventional welding struggles: near heat-sensitive components, on thin-to-thick joints, and on finished or coated assemblies where distortion would be visible.
Operators reach working proficiency in days. TIG takes months.
That difference is the main reason shops buy the technology. It separates welding capacity from the supply of certified welders, so you can add output without competing for a labour pool that is not growing.
Results are also more consistent between operators, because much less of the outcome depends on hand technique. That tends to matter most on repeat production work, where variation between welders shows up as variation in the finished product.
Handheld laser welding runs about 4 times faster than MIG or TIG on comparable joints.
The speed comes from a concentrated energy source and much lower heat input. The lower heat input is arguably the bigger effect: less distortion on thin sheet means less post-weld straightening, and cleaner welds mean less grinding and polishing.
On thin stainless the finishing time saved is often larger than the welding time saved, which is why a straight arc-time comparison usually understates the difference.
The handheld head runs four modes: weld, clean, light cut and seam-clean.
The cleaning modes matter more than they sound. Pre-weld cleaning and post-weld seam cleaning are normally separate operations with separate equipment, so doing them with the same head means the part does not move between stations and the operator does not change tools between steps.
Single-wire feed is standard, with dual-wire available as an option.
Single-pass capability is up to 0.24 in (6 mm) at 1.5 kW, up to 0.31 in (8 mm) at 2 kW, and up to 0.39 in (10 mm) at 3 kW.
Most shops buy on the joints they run every day rather than the thickest joint they can imagine. Laser welding's advantage is largest on thinner material, where conventional heat input causes the distortion that forces straightening and rework, so sizing up for an occasional heavy joint often buys capability in the wrong place.
Vantix handheld laser welders are available air-cooled in 1.5, 2 and 3 kW, and water-cooled in 2 and 3 kW.
Cooling type is a separate decision from power. Air-cooled units are lighter and easier to move around a shop or between sites; water-cooled units are built for sustained high-duty-cycle production. The deciding question is usually how much of the shift the welder is actually running, not how thick the material is.
Both configurations ship with the same 4-in-1 multi-function head.
Yes. Both series are automation-ready over EtherCAT and Profinet, so the head can be mounted on a robot or gantry and driven from a cell controller rather than held by an operator.
Operator-facing controls include eight selectable scan patterns, a maximum scan width of 300 mm, and a touchscreen HMI with dynamic alarm display. Dual red-light preview shows the scan area before the laser fires, which matters as much in a fixed cell as in the hand: it is how you confirm the part is positioned correctly without a test pass.
The most common uses are weld preparation, paint and rust stripping, mold cleaning, heritage restoration, and mining and MRO equipment refurbishment.
Supported substrates include steel, stainless, aluminum, bronze and titanium. Pulsed systems extend to cast iron, stone, concrete and wood, which is what makes restoration and masonry work practical rather than only metal cleaning.
If you have a surface that is currently blasted, stripped with chemicals, or cleaned by hand, it is worth testing on a sample before assuming which category it falls into.
