 The characteristics of laser welding technology

The laser welding machine uses high-energy laser pulses to locally heat the welding material in the micro-region, laser welding machine for metal and internally diffuses and melts the material through heat conduction to achieve the purpose of welding. It can be spot welding or continuous seam welding, butt welding, lamination welding, sealing welding, etc., with high aspect ratio, small weld width, small heat affected zone and small deformation. The absorption and purification of non-metallic impurities by high-temperature heat sources can greatly improve the welding effect. The material is low in pollution and small in impurity content, which greatly improves the strength and toughness of the material and even exceeds the parent metal. Laser welding machines rely on their high welding aspect ratio, small weld width, small heat affected zone, small deformation and other significant advantages have gradually replaced the traditional welding machine in various fields of welding. The high precision and high controllability of the laser welding machine maximizes the machining of precision parts, especially the low machining loss and low maintenance. Therefore, it is widely used in microelectronic components, integrated circuits, sensors, and small pressures. Precision parts such as containers, fiber optic coincidence devices, transformers, lithium batteries, watches, glasses, medical equipment, electronic components, precision connectors, handicrafts, etc.

300w laser welding machine Spot welding is an important and basic aspect of laser welding technology. When laser radiation heats the surface of work-piece, the surface heat diffuses to the interior through thermal conduction and melts the work piece by controlling the width, energy, peak power and repeating frequency of laser pulse to form specific molten pool. Because of this unique feature, it is widely used in processing of precious jewelry or welding of precision parts.
