What is a hand-held optical fiber laser welding machine?
Hand-held optical fiber laser welding machine is a new generation of laser welding equipment, which belongs to non-contact welding and does not require pressure during operation. Its working principle is to direct high-energy laser beam onto the material surface, through the interaction between the laser and the material, the material is melted inside, and then cooled and crystallized to form the weld.
the previous fixed light path with the hand-held type, is flexible and convenient, and the welding distance is long, it also makes it possible for laser welding to be done outdoors.
The hand-held welding is mainly aimed at the laser welding of long-distance and large workpieces, which overcomes the limitation of the travel space of the worktable, and the small heat-affected area during welding will not cause the problems of deformation, blackening and back trace, and the welding depth is large, solid welding, full melting, not only can realize heat conduction welding, but also can continuously deep penetration welding, spot welding, butt welding, lap welding, seal welding, seam welding and so on.
This technology overturns the working mode of the traditional laser welding machine. It has the advantages of simple operation, beautiful welding seam, fast welding speed and no consumables, can perfectly replace the traditional argon arc welding, stainless steel plate, iron plate, aluminum plate and other metal material welding.
Advantages of hand-held laser welding machine
1. Wide welding range: hand-held welding joint equipped with 5M-10M original optical fiber, overcome the limitation of worktable space, can be outdoor welding, long-distance welding;
2. Easy to use: hand-held laser welding equipped with movable pulley, comfortable grip, adjust the work position at any time, no fixed position, free and flexible, suitable for all kinds of work environment scenarios.
3. Various welding methods: welding at any angle can be realized: overlap welding, butt welding, vertical welding, flat angle welding, inner angle welding, outer angle welding, etc. . To achieve any angle of the welding. In addition, he can also complete cutting, welding and cutting free switching, just change the welding copper nozzle for cutting copper nozzle can be very convenient.
4. Welding effect is good: hand-held laser welding is hot fusion welding, compared to traditional welding, laser welding has a higher energy density, can achieve better welding effect, welding area heat effect is small, not easy to deformation, blackening, back trace problem, the welding depth is big, the fusion is full, the firm is reliable, the welding seam strength achieves even surpasses the base material itself, this is ordinary welding machine can not guarantee.
5. Welds do not need to be polished: after traditional welding, the welding point needs to be polished to ensure smooth and not rough. The hand-held laser welding just reflects the processing effect of more advantages: continuous welding, smooth no fish scale pattern, beautiful no scars, less follow-up grinding process.
6. Welding consumables: in most people’s impression of the welding operation is “Left hand goggles, right hand clip wire.”. But with the hand-held laser welding machine can easily complete welding, more reduce the cost of production and processing of materials.
Kill. With a plurality of safety alarms, the welding nozzle is effective only when it touches the metal, automatically locks the light when the workpiece is removed, and the triggering switch is temperature-sensitive. High Security, to ensure the safety of operators during the work period.
8. Save labor cost: compared with arc welding, the processing cost can be reduced about 30% . The operation is simple and easy to learn, the operator technical threshold is not high, ordinary workers can be trained for a short time, can easily achieve high-quality welding effect.
Comparison between hand-held laser welding machine and argon arc welding
1. Energy consumption comparison: compared with traditional arc welding, hand-held laser welding machine can save about 80% ~ 90% power, processing costs can be reduced by about 30% .
2. Comparison of welding effects: laser hand-held welding can complete dissimilar steel and dissimilar metal welding. Fast speed, small deformation, small heat-affected zone. The welds are beautiful, flat, no/less blowhole, no pollution.
3. Follow-up process comparison: laser hand-held welding heat input is low, workpiece deformation is small, can get a beautiful welding surface, without or only need a brief treatment (depending on the requirements of welding surface effect) .
Application Field of hand-held laser welding machine
Mainly for large and medium-sized sheet metal, cabinets, chassis, aluminum alloy door and window frame, stainless steel wash basin and other large workpiece fixed position such as inside right angle, outside right angle, plane welding seam welding, welding heat affected area is small, small deformation, and welding depth, welding firm. Widely used in kitchen and bathroom industry, home appliances industry, advertising industry, mold industry, stainless steel products industry, stainless steel engineering industry, doors and windows industry, arts and crafts.
