The regular monthly check once every one to the battery voltage to ensure that the minimum battery voltage of not less than 3V below 3V 2:00 charging and discharging process. 2.2 Zhengzhou Siwei Mechanical and Electrical Equipment Manufacturing Co., Ltd. 2.2.1 Company Introduction Zhengzhou Siwei Mechanical and Electrical Equipment Manufacturing Co., Ltd. is one of the IMM International Coal Group, one of the five machines manufacturing base is located in the Central Plains, Zhengzhou High-tech Zone Jinsuo Road on the 7th. High-tech enterprise in Henan Province, Zhengzhou High-tech Zone focus on supporting the Henan Province, the first manufacturing demonstration unit has passed the ISO9001: 2000 quality system certification, ISO14001-2004 environmental management system certification, GB/T28001-2001 Occupational Health and Safety Management system certification. The drawing of  green laser pointer should be prepared at the same time.
In addition, electron beam welding speed is very fast, to save time I save a lot of manpower; high precision electron beam welding, can guarantee that the product is welded out of high-quality, long life. Thus greatly improve the corporate image of the next house. Understanding of practice is an important part of the teaching of engineering practice, its purpose is to enable our students personally to the production line to lectures and master workers who live their own experiences to a comprehensive and detailed understanding of the process of the related materials by teachers and engineering and technical personnel Church. The internship process, we can obtain from the technicians and workers direct and indirect production experience. Normally, the back order of the green  green laser pointer should be avoided. 
For example, resistance spot welding, laser welding and electron beam welding lap joint is often used. However, some of the welding process, such as manual metal arc welding, almost you can use any connector type. It is worth mentioning is that some welding process allows a number of welding: a welding weld cooling after welding time on the basis of This V-shaped butt joint welding thick workpieces. A cross-section of welded joints, the darkest part of the welding area or melted zone, the shallow part of the heat-affected zone, the shallowest part of the color after the end of the base metal welding, the weld near the material shows several differences obvious area.
