Fiber Laser Welding Machine-Jewellery Welder

Fiber laser welding machine has the advantages of simple operation, beautiful weld seam, fast welding speed, and no consumables. It can be used for welding various metals sheets and tubes: such as stainless steel plates, iron plates, galvanized plates and CS plates, aluminum plates, brass plates, other metal sheets, and tubes.

The jewellery welder system combines the fundamental qualities of an ultra-portable device with uncompromising performance. With our new design, the product’s overall volume has been reduced dramatically. This results in an extremely productive and powerful system. This device is a perfect integration of igoldencnc Group’s Laser Welding Technology and reliable portable structure. The System is a fit for complex components as well as large and small components. 

Comparison between fiber laser welding machine and argon arc welding

1. Energy consumption comparison: Compared with traditional arc welding, hand-held laser welding machine saves about 80%~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 with small deformation thanks to the small heat-affected zone. The weld seam is beautiful, smooth, no/less porosity, with very little pollution. The handheld laser welding machine can be used for small open parts and precision welding.

3. Subsequent process comparison: low heat input during laser hand-held welding can do very small deformation of the workpiece. In the meantime, beautiful welding surface can be obtained, so no or only very simple treatment (depending on the requirements of the welding surface effect) is needed. The handheld laser welding machine can greatly reduce the labor cost of the huge polishing and leveling process.

Advantages of jewelry laser welder:

1. Wide welding range: The handheld welding head is equipped with 10m original optical fiber, which overcomes the limitation of the workbench space, and can be welded outdoors and used for long-distance welding;

2. Convenient and flexible operation: hand-held laser welding is equipped with movable wheels, which is easy for transportation and can adjust the working position at any time. It is flexible and suitable for various working scenarios.

3. A variety of welding methods: welding at any angle can be realized: overlap welding, butt welding, vertical welding, flat fillet welding, internal wire-filler welding, external wire-filler  welding, etc., It can be used for various complex and large workpieces with irregular-shaped welding.

4. Good welding effect: Hand-held laser welding is thermal fusion welding. Compared with traditional welding, laser welding has a higher energy density and can achieve better welding results. The welding seam strength reaches or exceeds the base metal itself, which cannot be guaranteed by ordinary welding machines.

5. The welding seam does not need to be polished or ground: after traditional welding, the welding point needs to be polished to ensure smoothness. The hand-held laser welding can perform continuous welding, smooth and beautiful without any welding scars, which saves follow-up polishing procedures.

What Are the Properties of fiber laser welding machine?

fiber laser welding machine has a high power density that’s of the order 1 MW per square centimeter. Due to this high energy density, it has few heat-affected areas. The procedure also has a high heating and cooling rate.

The laser gleams generated stick together. They also have a similar wavelength (monochromatic).

You can use laser welding to weld smaller spot sizes. However, the sizes of the spots differ from 2 to 13 mm.

The penetration depth of laser beam welding relies on the amount of power supply and the concentration point location. It’s commensurate to the power supply amount. If the concentration point is kept somewhat beneath the workpiece surface, the penetration depth is maximized.

In laser welding, you can use constant or pulsed laser gleams. When laser welding slender materials, you’ll use millisecond-pulses, and if you want deep welds, use constant laser beams.

Laser beam welding is a versatile procedure as you can use it to weld stainless steel, aluminum, HSLA steel, carbon steel, and titanium. However, when laser welding carbon steel, you’ll have an issue with cracking because of the high cooling rate.

Laser welding heat conduction

jewellery welder is to irradiate a high-intensity laser beam to the metal surface, and through the interaction between the laser and the metal, the metal is melted to form a weld. Metal melting is only one of the physical phenomena during the interaction of the laser with the metal. Sometimes light energy is not mainly converted into metal melting, but manifested in other forms, such as vaporization, plasma formation, etc. However, to achieve good fusion welding, metal melting must be the dominant form of energy conversion. To this end, it is necessary to understand the various physical phenomena generated in the interaction between laser and metal and the relationship between these physical phenomena and laser parameters, so that most of the laser energy can be converted into metal melting energy by controlling the laser parameters to achieve welding.
