What kinds of materials and thicknesses can handheld laser welders handle?
Most models weld stainless steel, mild steel, aluminium, and copper. Typical units handle up to 3-4 mm thick material depending on power and setup. Higher-output lasers can manage thicker seams or reflective metals with multiple passes.
Why use a handheld laser welder instead of TIG or MIG?
Handheld Lasers deliver faster, cleaner welds with less heat distortion, spatter, or grinding, however they have a limited thickness to work with compared to TIG or MIG. They also use fewer consumables, weld up to four times quicker, and reach tight spaces or field repairs where fixed gear can't.
What key specifications should I compare when choosing a handheld laser welder?
Focus on power (watts), cooling type, duty cycle, and beam quality. Also check preset modes, shielding gas options, and not the mention the welder's age and history, they all affect ease of use and reliability on the second hand market.
