Laser welding technology is a high-tech, because of its unique characteristics, particularly suitable for use in the sensor seal Welding Electrode current sensor manufacturers abroad, many producers are using laser welding process to produce sensor, while domestic manufacturers are not using this technology more, mainly by the production of military products, manufacturers and part of the sensor research institutions in the use of such technology, and using more foreign laser welding machine. At present, the performance of laser welding machines and foreign products have been far off, fully capable of sensor technology requirements of domestic production, but the price is similar foreign products 1/3-1/5. To improve the overall level of internal sensors and the development of national industry, laser, sensor manufacturers in China should be made as soon as possible the use of laser welding machine to the production and processing sensor, in order to increase product competitiveness, international markets.
