Laser Welders

Lincoln Electric's laser welder lineup includes the Flex Lase™ Handheld Laser Ready-Pak® (K5772-1) for portable, manual laser welding, cleaning, and cutting, as well as the Laser-Pak® robotic laser systems (PPL, XFT, XL variants) for automated production. The Linc-Cut™ series handles CNC laser cutting, with the 3015 at 4 kW and the 1530S at 6 kW and 12 kW power levels. The cobot-based Flex Lase™ Cobot Cart and ClassMate® Laser Cobot are designed for collaborative robot-guided applications. Together, these products cover handheld manual, semi-automated cobot, and fully automated robotic laser processing.

Handheld fiber laser welders like the Flex Lase™ are well suited for welding thin-gauge stainless steel, mild steel, galvanized steel, aluminum, brass, and copper — materials that are problematic or labor-intensive with conventional arc processes. Typical thickness range for handheld laser welding is 0.02 in. to about 0.2 in. (0.5–5 mm), depending on power and travel speed. Accessories available for the Flex Lase™ include HyperFill® wire feeding for 0.035-in. wire (K5913-1) and an aluminum wire feeding option for 1/16-in. wire (K5914-1), allowing filler metal addition for gap bridging and reinforcement.

The Linc-Cut™ 3015 at 4 kW is suited for cutting mild steel up to approximately 5/8 in. (16 mm) and stainless up to about 3/8 in. (10 mm). The Linc-Cut™ 1530S at 6 kW handles thicker material and provides faster cutting speeds on thinner material compared to the 4 kW unit. The 12 kW shuttle system is designed for high-production environments cutting material up to 1 in. (25 mm) or thicker and with significantly higher throughput. The shuttle table configuration on the 1530S models reduces downtime by allowing continuous material loading while the other table is cutting.

Laser welding and cutting requires Class 4 laser safety protocols: enclosed work areas or light-tight curtains, appropriate laser-rated safety glasses (OD rating matched to the laser wavelength — fiber lasers operate at ~1,064 nm), and restricted access to the beam path. The AWS Welding Handbook notes that laser beam cutting and welding also generates fine metallic particulates, ozone, and nitrogen oxides that require local exhaust ventilation comparable to arc welding. All personnel in the work area must wear appropriate eye protection and follow the machine-specific safety procedures detailed in the operator's manual.
