Application of sensor laser welding

In recent years, laser welding has become more common in the field of sensor applications. The laser welding technology of Laser Welding Machine manufacturers is a high-tech technology. Because of its unique characteristics, it is especially suitable for application in the sealing welding of sensors, and has obtained a large number of applications. The company's concern, the selection of laser welding sensor products, in order to enhance the competitiveness of products, the development of foreign markets.

Processing characteristics of laser welding in the production of sensors - the use of lasers to seal and weld the plastic shell of the sensor is a good manufacturing process at this stage. The key points are that laser welding has the following characteristics:

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

(2) Hot typing. Because of the high power, the whole melting process is very fast, the calorific value of the typed product workpiece is very low, the welding speed is faster, the thermal deformation is small, and the thermal hazard area is small;

(3) High density. During the whole process of welding transformation, the molten pool is continuously stirred, and the vapor is easy to come out, resulting in the transformation into penetration welding without vent holes. The high cooling rate after welding is easy to micro-optimize the welding mechanism, and the welding compressive strength, ductility and comprehensive performance are high;

(4) Solid welding. High temperature pyrogen and sufficient digestion and absorption of non-metallic materials have resulted in purification effect, reducing residue components, changing impurity specifications and its distribution in the molten pool, and no electric grade or filling electrode is required in the whole process of electric welding. , the melting zone is less polluted by the environment, so that the compressive strength and ductility of the welding are less equal to or even beyond the metal materials of pregnant mothers;

(5) Precise manipulation. Due to the small focus point, the welding can be positioned and navigated, and the light is very easy to transmit and manipulate. It is not necessary to frequently replace the welding torch and nozzle, which significantly reduces the auxiliary time for shutdown. Downward change and start again. With the automatic control of light movement technology, complex prefabricated components can be welded;

(6) The whole process of non-contact, ambient air electric welding. Since the kinetic energy comes from the laser, there is no physical contact of the product workpiece, so no force is added to the product workpiece. In addition, magnetism and gas are not harmful to the laser;

(7) Because of the low average heat input and high processing accuracy, the cost of reproduction and processing can be reduced. In addition, the operating cost of laser welding is low, which can further reduce the cost of product workpieces;

(8) It is very easy to complete the automation technology, and can carry out reasonable control of the light compressive strength and precise and precise positioning.
