How much power is required for laser welding?

Question

Accepted Answer

Laser welding power is set by material thickness and type. For thin stuff material less than 1 mm, a power level from 500 to 1500 watts will do. Materials of moderate thickness, about 1 to 3 mm, need 1500 to 3000 watts. For sections more than 3 mm, the power must go up to 3000 to 6000 watts, perhaps higher. One kilowatt of laser power per millimeter of material thickness is a good standard when welding at 2 meters per minute. Too much power on thin material may give defects, such as burn-through. With too little power on thick material, welds may be weak. Correct power selection makes welds that are substantial, clean as well as get the job done for diverse uses.
