Available Upgrades
01
Laser Welding — 5× Faster Than TIG, No Wire on Tight Joints
The handheld laser welding head welds autogenously — no filler wire, no electrodes — on tight-fit butt joints, lap joints, T-joints, and fillets on stainless, carbon steel, and aluminum. When joints have gaps or the application requires filler for code compliance, the wire-feed mode supplies wire directly into the weld pool. Weld speed is 3–5× faster than TIG, and the wobble function produces a cosmetic bead that needs no grinding.
02
Laser Cutting Head — Handheld Plate and Profile Cutting
Swap to the cutting head for handheld precision cuts on flat sheet, plate, and profiles. The laser cutting mode uses assist gas (nitrogen or air) to blow the melt through the kerf. Suitable for straight cuts, curves, and cutouts in thin-to-medium sheet — useful for on-site work, field repair, and short-run custom parts that don't justify CNC setup.
03
Laser Cleaning — Remove Rust, Paint, and Oxide Instantly
The cleaning head directs high-frequency pulsed laser energy at the surface, ablating rust, mill scale, paint, oil, and oxide layers without touching the base metal. No chemicals, no abrasives, no media disposal. Used for pre-weld surface prep, rust removal, and coating removal on finished parts. Replaces angle grinder prep on weld seams.
04
Wire-Feed Welding — Fill Gaps and Hard-Facing
The fourth mode adds a wire feed nozzle to the welding head, supplying filler wire into the weld pool. This extends the machine's capability to gap-bridging applications, dissimilar metal joining, and hard-facing overlays. Wire feed speed is adjustable; the operator controls travel speed and wire deposit rate manually for maximum flexibility on irregular joints.
05
All Common Metals — Including Reflective Alloys
The VTM-4W's fiber laser source excels on reflective metals that challenge CO₂ systems. Carbon steel, stainless steel, aluminum, brass, copper, galvanized steel, and titanium alloys — all processable with the same machine. The anti-reflection protection circuit in the welding head prevents back-reflection from copper and brass from damaging the source.

Technology
4-in-1 Laser vs. Conventional Weld Setup
| Feature | VTM-4W Laser | TIG / MIG + Grinder |
|---|---|---|
| Weld speed (thin stainless, <3mm) | 3–5× faster | Baseline |
| Post-weld grinding required | No — bead is cosmetically finished | Yes for most applications |
| Filler wire consumption | None (welding mode) / Minimal (wire-feed) | Consumable cost per foot of weld |
| Shielding gas consumption | Minimal (localized shield at head) | High (TIG) / Moderate (MIG) |
| Rust / oxide removal | Laser cleaning mode, same machine | Separate grinder or blaster |
| Surface prep before weld | Laser clean in place, no grit contamination | Grind, wire brush, or solvent wipe |
| Dissimilar metals / gaps | Wire-feed mode handles gap bridging | Standard MIG/TIG capability |
| Heat affected zone (HAZ) | Narrow — minimal distortion | Wider HAZ, higher distortion risk |
| Operator certification required | No — lower learning curve than TIG | TIG requires certified welder |

Frequently Asked
No. The handheld laser welding head is significantly easier to operate than TIG — the beam does the work, and the operator guides the head along the joint. Most operators are production-ready within a day of training. VTM provides on-site training with every machine.
Yes for most applications. Tight-fit butt joints and lap joints on stainless and aluminum weld cleanly in welding mode without filler. For gap bridging, dissimilar metals, or structural welds requiring filler for code compliance, use the wire-feed mode.
Argon is standard for stainless and aluminum welding. Nitrogen works for carbon steel. The gas nozzle is integrated into the welding head — consumption is low because the shield is applied locally at the weld pool rather than flooding the entire joint.
On carbon steel: up to 4 mm (0.16") at 1.5 kW, up to 8 mm (0.31") at 3 kW in a single pass. Stainless is similar. Aluminum requires slightly higher power due to thermal conductivity. Multi-pass welds can address thicker material.
Yes when used correctly. The pulsed laser ablates the surface layer — rust, mill scale, paint, or oxide — without significantly heating the base metal. Parameters (power, frequency, speed) are adjustable for surface sensitivity. Ideal for pre-weld cleaning, post-weld oxide removal, and coating removal on localized areas.
Yes. The VTM-4W uses the same laser source regardless of configuration — additional head types (cutting head, wire-feed kit) can be added post-purchase. Contact your VTM sales engineer to confirm compatibility with your specific unit.
