What you should know about handheld laser welding machine?

 The basic principle of handheld laser welding machine

1. Basic principles of welding

Laser welding uses a single pulse of a high-efficiency laser to heat the small area of ​​the data. The power of the laser radiation source spreads to the inside of the data according to the heat conduction, and the data is melted to produce a special molten pool. It is a new type of welding method. The key is to weld thick-walled raw materials and high-precision parts. Welding, butt welding, overlap welding, sealing welding, etc. can be established. The deep layer is relatively high, the overall welding width is small, and the heat hazard zone is small. Small deformation, faster welding speed, smooth welding, beautiful appearance, no disposal or simple solution after welding, high welding quality, no air vents, maneuverable, small focus spot, high precision level, easy to complete automation technology.

2. Machine and equipment characteristics

The automatic laser welding machine adopts imported parts, with stable characteristics, low equipment failure rate, and service life of nearly 10 years; the welding is highly efficient, the effect is very good, the actual operation is simple and convenient, and the key selection program programming is fully automatic or full. Automatic welding, butt welding, stitch welding, airtight welding, and welding of complicated horizontal parallel lines, arcs, and random motion trajectories. Can be customized according to user needs.

3. The scope of application

Laser welding machines can be used: power lithium batteries, electronic components, sensors, clocks, precision machinery and equipment, communications, medical machinery, kitchen supplies, sanitary ware, door handles, collets, vehicle airbags, automotive filters, Car headlights, vehicles, and another high-hardness commodity welding.

4. Product advantages

(1) High aspect ratio. The welding is deep and narrow, and the welding is bright and beautiful.

(2) Least hot keying. Because of the high power, the whole melting process is very fast, the heat of the input product is very low, the welding speed is faster, the thermal deformation is small, and the thermal hazard is small.

(3) High compactness. During the whole process of welding formation, the molten pool continues to mix, and the vapor is easy to escape, resulting in the transformation into through-hole welding without vent holes. The high cooling efficiency after welding is easy to optimize the welding arrangement, and the welding compressive strength, ductility, and comprehensive performance are high.

(4) Firm welding. The high-temperature pyrogen and the complete digestion and absorption of the two components of non-metallic materials result in the purification effect, reducing the residue composition, changing the specifications of the impurities and their spreading in the fusion, and the whole welding process does not require electric grade or filling electrodes to melt. The area is less polluted by the environment so that the welding compressive strength and ductility are at least equal to or even beyond the pregnant metal material.

(5) Manipulation. Due to the small focus spot, the welding can be positioned and navigated, the light is very easy to transmit and manipulate, and there is no need to frequently disassemble and replace the welding torch and nozzle, which significantly reduces the shutdown auxiliary time, and the production efficiency is high. Change direction down and start again.

(6) The whole process of non-touch and ambient air welding. Since the kinetic energy is from the laser, the product workpiece has no physical touch, so there is no force to release the product workpiece. In addition, the electromagnetic field is not harmful to laser welding.

(7) Because the average thermal input is low and the processing accuracy is high, the reproduction processing cost can be reduced. In addition, the laser welding operation cost is lower, which can reduce the cost of the product and the workpiece.
