The IGOLDENCNC aluminium laser welding machine uses the xenon lamp to generate a certain wavelength of light source, and the crystal rod to achieve pumping, to generate laser light.
It is easy to use and allows high-quality laser welding to be performed with less burn and distortion.
It adopts a laser crystal that offers the highest power yield of all laser media and technologies. Specific to the advertising industry, it can accurately weld small and complex metal font and LOGO, and features fast speed, no color difference after welding, no trace, no need to handle, beautiful appearance.
Furthermore, the handheld laser gun is very flexible for large-size thin materials, precision parts welding, as well as spot welding, butt welding, overlap welding of carbon steel, stainless steel titanium, aluminum, copper, zinc, gold, silver and many other metals and alloy, and also copper-brass, cooper-titanium, nickel-cooper, cooper-titanium and many other heterogeneous metals.
1. Hand-held laser welding machines generally have the advantages of simple operation, beautiful welding seams, fast welding speed, and no consumables. They can be used to weld thin stainless steel plates, iron plates, galvanized plates and other metal materials, which can perfectly replace traditional argon arc welding. Electric welding and other processes.
2. The hand-held laser welding machine can be widely used in the complicated and irregular welding processes of cabinets, kitchens and bathrooms, stair elevators, shelves, ovens, stainless steel door and window guardrails, power distribution boxes, stainless steel home appliances and other industries.
3. Hand-held laser welding is fast, 2-10 times faster than traditional welding. A laser welding machine can save at least 2 welders a year. The welding seam of handheld laser welding is smooth and beautiful, which reduces the follow-up grinding process and saves a lot of time and cost.
4. The laser welding workpiece has no deformation, no welding scar, and the welding is firm. In addition, the laser welding consumables are few, and the service life is long.
Aluminium laser welding machine Safety Tips
welding machine aluminum laser are generally used for tailor welding and repair welding of metal materials. The whole process of laser welding is that the materials are in a high temperature state, so how should we use the handheld laser welder safely?
1. During the operation, if there is an emergency, such as water leakage or abnormal laser sound, you need to immediately press the emergency stop button and quickly cut off the power supply.
2. The external circulating water switch of laser welding must be turned on before operation. Because the laser system adopts water cooling method, the laser power supply adopts air cooling method. If the cooling system fails, it is strictly forbidden to start working.
3. It is strictly forbidden to touch all circuit components in the machine while working. When the laser welding machine is working, the circuit is in a high voltage and high current state. Untrained personnel are prohibited from operating the machine.
4. It is strictly forbidden to directly use the eye scanning laser when the laser is working to avoid eye injury. It is forbidden to use external equipment to reflect laser light during laser work.
5. Do not disassemble any parts of the machine at will, and do not weld when the safety door of the machine is opened, and do not aim the laser head at the equipment parts.
6. Do not place flammable and explosive materials where the laser light path or laser beam can be irradiated to avoid fire and explosion.
How does a high-power, high-brightness fiber laser welding machine weld copper materials?
1. The high power density required for welding copper materials can be obtained by using a single-mode fiber laser.
Compared with other solid-state lasers, this type of laser has excellent beam quality and focusing performance. IPG can provide high-power single-mode lasers up to 10 kW, and high-brightness multi-mode lasers with power over 10 kW, all of which have rugged and industry-proven designs.
Using these single-mode fiber lasers and low-order mode high-brightness lasers, a power density higher than 108W/cm² can be achieved, and reliable coupling can be achieved even at a power of several hundred watts. Compared with ordinary multimode lasers of comparable power, these lasers are up to fifty times stronger.
2. Aiming at the instability of the copper welding process at low speed welding
Generally, welding speeds less than 5m/min will face welding instability problems, such as spatter, porosity and irregular weld surface.
As the welding speed increases, this instability gradually disappears. In the welding speed range of 5-15m/min, the quality reaches an acceptable level. If the welding speed is higher than 15m/min, the weld produced is basically free of defects (Figure 3). This means that the best welding parameters are within the limits that traditional motion systems (such as robots) can achieve.
3. The impact of the swing amplitude of the welding head on the width and quality of the weld
As the swing diameter increases and the speed of the circular beam increases, the surface quality becomes more and more stable. Depending on the swing parameters and spot size, the light beam and the formed keyhole usually move in a molten metal pool or in solid and resolidified materials. In both cases, the brazing process can achieve stability.
In addition, the swing diameter can be used to customize the shape of the weld cross-section, as follows:
A small swing diameter will form a typical V-shaped cross section for laser welding;
The larger diameter can change the welding seam from a V shape to a U shape or a very regular rectangle;
If the energy input per unit length of the weld is constant (E = P vw), the cross section of the weld remains almost unchanged.
4. Brightness fiber laser can overcome all known problems in copper welding applications.
1) High power density can realize instantaneous coupling and formation of keyholes, and can realize stability and high absorptivity even at a wavelength of 1070nm.
2) Through the highly dynamic beam swing, the welding process is very stable, thereby reducing or avoiding the phenomenon of pores and spatter, and finally produce high-quality welds.
