1.Energy consumption comparison Compared with traditional arc welding, the hand-held laser welding machine saves about 80% to 90% of electric energy, and the processing cost can be reduced by about 30%.
2.Welding effect comparison Laser hand welding can complete dissimilar steel and dissimilar metal welding. Fast speed, small deformation and small heat affected zone. The welds are beautiful, flat, no/less pores, and no pollution. Handheld laser welding machines for tiny open parts and precision welding.
3.Follow-up process comparison During laser hand-held welding, the heat input is low, the deformation of the workpiece is small, and a beautiful welding surface can be obtained, without or only a simple treatment (depending on the welding surface effect requirements). The hand-held laser welding machine can greatly reduce the labor cost of the huge polishing and leveling process.
