1.Energy consumption comparison:
Compared with traditional arc welding, the handheld 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-held welding can complete dissimilar steel and dissimilar metal welding. The speed is fast, the deformation is small, and the heat-affected zone is small. The weld seam is beautiful, smooth, no/less porosity, and no pollution. The handheld laser welding machine can be used for small open parts and precision welding.
3.Comparison of follow-up processes:
During laser hand-held welding, the heat input is low, the deformation of the workpiece is small, and the beautiful welding surface can be obtained without or only simple treatment (depending on the requirements of the welding surface effect). The hand-held laser welding machine can greatly reduce the labor cost of the huge polishing and leveling process.
