- Introduction of jewelry laser spot welding machine:
Jewelry laser spot welding machine is to achieve high-density energy acting on the object through the laser beam emitted by the laser to achieve the precise welding effect. The welding process is to heat the workpiece on the laser processing, the laser beam is aimed at the position of the workpiece, and the surface heat is heated to the inside of the workpiece. During the work, the pulse width, energy, pre-repetition frequency and other parameters are controlled to melt and form a molten pool. Welding effect.
Laser welding technology is a process that is applied to thin-walled materials and precision welding. It has obvious advantages in spot welding, butt welding, overlap welding, and sealing welding. It has a high aspect ratio (5:1 or 10:1), heat Small deformation, fast welding speed, no porosity, smooth welding seam, beautiful appearance and no need for treatment and micro-processing after welding. During the welding process, the welding effect is controllable, accurate positioning can be achieved, and it can be fully automated.
Jewelry laser spot welding machine is a special equipment for welding supply holes, sand holes and spot welding of gold and silver jewelry. Spot welding technology in laser welding is widely used. The internal concurrency of the laser pulse is controlled by operation to control the width, energy, predetermined power and repetition frequency of the laser pulse, so that the workpiece is synthesized to form a specific molten pool. Because of its unique advantages, it has successfully processed gold and silver jewelry and welded micro and small parts.
- Features of jewelry laser spot welding machine:
Adjustable parameters (such as energy, pulse width, frequency, spot diameter), can realize different welding requirements;
Use automatic shading device to protect the eyes of the operator during work;
Continuous work for 24 hours, stable performance of the whole machine;
The laser beam can split the light in time and energy, and can process multiple beams at the same time. The welding speed is obviously improved, so that the user can complete the processing order efficiently and at a high level in a short time;
Laser welding is seamless welding without external force;
The energy is highly concentrated during the welding process, no consumables are needed during welding, and it is allowed to be at least equivalent to the parent material after welding;
The current laser waveform of the welding equipment can be set arbitrarily, which can be applied to various materials to achieve the best results;
It can reduce the input quantum to minimize the deformation of the heat-affected zone;
When welding, no electrode is used, the whole welding process is non-contact, and there will be no concerns about electrode contamination and damage;
Laser welding can realize welding in a vacuum environment, and can weld through glass or materials that are transparent to the beam;
The laser beam can be focused on a small area and can weld small and closely spaced parts;
Wide variety of welding materials, different materials can be welded together;
It can realize high-speed welding under automation, and it can also be controlled by digital or computer to realize precision processing;
No reflow phenomenon occurs during welding;
It is not restricted by the site environment (such as electromagnetic field interference), and can weld accurately and accurately;
For metals with high melting point, refractory and difficult to weld, it can be easily welded (like titanium alloy, aluminum alloy, etc.) with good results;
The mechanical strength after welding is often higher than that of the base metal;
The mechanical properties, axial properties and electromagnetic properties of laser welding are superior conventional welding methods;
Using professional motion control software and single-chip microcomputer to set the graphics mode, it can complete automatic or semi-automatic spot welding, butt welding, stack welding, sealing welding, single-section straight line, arc welding and other trajectory welding in the plane;
Professional workbench design, easy to clean and recover precious metals;
Advanced fume exhaust system to quickly and effectively exhaust fumes from the working chamber during welding;
Scientific and humanized design, ergonomics, long-term work without fatigue.
