Hand held laser welding machine is a new generation of laser welding equipment, which belongs to non-contact welding. Pressure is not required in the actual operation process. Its basic working principle is to irradiate the high-energy laser beam directly on the material surface. Through the interaction between laser and material, the interior of the material can be melted, and then cooled and crystallized to form weld.
The hand-held laser welding machine fills the vacancy of hand-held welding in the laser equipment industry, refreshes the traditional laser welding working mode, and replaces the previous fixed optical path with hand-held, which is flexible, convenient and fast, and has a long welding distance, so that laser welding can also be used outdoors.
Handheld welding is mainly used for laser welding of long-distance and large product workpieces, which overcomes the limitation of worktable travel space. During welding, the heat affected area is small, which will not cause deformation, blackening and impression on the back of the product workpiece, and the welding depth is large, the welding is firm and firm, and the melting is sufficient. It can not only realize heat conduction welding, but also realize continuous deep penetration welding, spot welding, butt welding, seam welding, seal welding, seam welding, etc.
This process refreshes the working mode of the traditional laser welding machine, and has the advantages of simple operation, beautiful weld, faster welding speed and no consumables. It is applicable to thin stainless steel plate, iron plate, galvanized plate, etc. the welding of metal materials can completely replace the traditional argon arc welding, stainless steel, iron, aluminum and other metal materials.
Comparison between handheld laser welding and argon arc welding
1. Comparison of energy consumption: compared with traditional arc welding, the handheld laser welding machine can save about 80% ~ 90% of electric energy and reduce the production cost by about 30%.
2. Comparison of welding effect: laser handheld welding can complete the welding of dissimilar steel and dissimilar metal. Faster speed, small deformation, small heat affected zone, beautiful and flat weld, no / few pores and no pollution. Hand held laser welding machine can carry out micro opening parts and precision welding.
3. Comparison of subsequent processes: during laser hand-held welding, the heat input is low and the deformation of product workpiece is small. Beautiful welding surface can be obtained without or only simple treatment (depending on the requirements of welding surface effect). Hand held laser welding machine can greatly reduce the labor cost of huge polishing and leveling process.
