SHINHOP laser

Welding Equipment: Domestic welding machines can be used for this welding work; automated welding equipment is used for filling and covering.
Welding Materials: Choose welding wire for root welding, such as 304 or 316 stainless steel wire rolls.
Bevel Cleaning: First, clean the bevel before assembly.
1. Advantages of Fiber Continuous Laser (Wavelength 1060-1080um) Welding:
1. Automation: High degree of automation, achieving high-precision welding, can be equipped with robotic arms, CNC machine tools, and sensor systems to detect process parameters and ensure welding quality.
2. Welding Speed: High production efficiency, fast speed reduces thermal stress and minimizes the heat-affected zone, resulting in less deformation of the workpiece.
3. Fine Welds, Smooth Surface: Reduces subsequent processes (such as polishing, grinding).
4. High Welding Strength: The welded workpiece can withstand bending or hydraulic forming.
5. Welding Penetration: Instant penetration (depending on power) can reach a depth of over 1CM.
6. Welding Pool: Through gas protection, the welding pool is free of pores and impurities.
7. Non-Contact: The welding process is non-contact with the workpiece. Minimal loss.
8. Strong Scalability: Replacement of components can achieve quenching, cladding, cutting, and other production processes.
9. Strong Configuration Capability: Can achieve wire feeding welding, oscillating welding, and handheld welding (flexible).
10. An environmentally friendly and safe welding process, with low welding usage costs.

2. Different Types of Laser Welding Heads Achieve Different Processes:
1. Laser Welding (Standard Welding Head, Oscillating Welding Head, Galvanometer Welding)
Standard Laser Welding: This is a process that uses laser to directly irradiate the surface of the metal, causing two metal workpieces to self-fuse. The standard laser welding head irradiates the laser onto the workpiece in a focused or defocused manner for welding.
Oscillating Welding Head: Can customize the width of the weld seam and refract the light into various patterns during welding to weld the workpiece. The advantage is that it can perform rough processing, suitable for welding workpieces with larger gaps in the weld seam.
Galvanometer Welding: Allows for large-area continuous welding or spot welding without rotating the welding head, with fast speed and ease of use.
2. Laser Quenching (Quenching Head)
Laser quenching technology uses a focused laser beam to irradiate the surface of steel materials, rapidly raising its temperature above the phase transition point. When the laser moves away, the rapid heat conduction from the still low-temperature inner material causes the heated surface layer to cool quickly below the martensite phase transition point, thus achieving surface phase transformation hardening of the workpiece. For example, the maximum hardened layer depth of laser melting quenching on large rollers can exceed 2 millimeters.
3. Laser Cladding (Cladding Head)
Laser cladding technology uses a laser beam and a powder feeder to clad a layer of material with special properties on the selected workpiece surface to improve the surface performance of the workpiece. For many easily worn parts in the metallurgical industry, such as rollers, guide rollers, conveyor rollers, clamping rollers, and cutting edges, the greatest benefit of laser cladding and alloying technology is that it transforms the overall alloying of rollers into surface alloying or cladding, significantly extending the service life of easily worn parts like rollers while keeping production costs limited. Clearly, the design, selection, and correct use of alloy powders are key to the success of this technology.
4. Laser Cutting (Cutting Head)
Laser cutting is a process that uses the energy released by laser irradiation on the workpiece surface to heat the workpiece instantly, cutting it with gas (air, nitrogen, oxygen).

3. Auxiliary System Configuration
1. Laser Wire Feeding Welding:
Configure a wire feeder with laser to achieve laser brazing functionality, suitable for welding products with large gaps that require filler.
2. Camera Positioning:
Take photos of the weld seam before welding, identify the position of the weld seam through image recognition, and control the light head for welding. The advantage is that it solves the problem of insufficient loading and unloading accuracy.
3. Seam Tracking:
Real-time identification of the weld seam position, controlling the laser head for welding. The advantage is fast speed and sensitive response!
Value of Laser Processing:
The largest cost of laser processing lies in the one-time investment in equipment, which is relatively expensive. Once the equipment is in place, the operating costs are relatively low without considering the equipment investment cost, and the processing cycle is short, which can greatly save maintenance time, ensuring timely production, and the performance is like new parts.
