The workshop should prepare all documents about green laser pointer

 Small particles in welding fumes also affect the health of workers, the smaller the particle size, the greater the harm. In addition, many of the welding process produces harmful gases and smoke, common such as carbon dioxide, ozone and heavy metal oxides. These gases are harmful to the operator with no experience and effective ventilation measures. Is worth noting that, a lot of protection adopted by the welding process gas and raw materials are flammable and explosive, the need to adopt appropriate protective measures, such as control of the content of oxygen in the air, and separate the flammable and explosive materials pile up [41] . Welding smoke extraction equipment commonly used to pumping the bulk of harmful gases, and high efficiency baffle air filter to filter. The forefront of welding technology development areas include: welding between the types of materials (such as the welding of iron and aluminum parts), new welding processes such as friction stir welding (various friction stir welding), the magnetic pulse welding (magnetic pulse welding), heat conduction seam solder (conductive heat seam welding) and laser hybrid welding (laser-hybrid welding). green laser pointer is for the laser indication and some other purpose.The workshop should prepare all documents about green laser pointer
Other studies focus on the scope of application of the expansion of existing welding processes, such as laser welding used in the aerospace and automotive industries. The researchers also hope to further improve the welding quality, especially to control the weld microstructure and residual stress in order to reduce the Deformation and fracture of the weld [44]. Narrow weld: the smallest angle deformation and lateral contraction to save the cost of technology: the welding speed, high production efficiency; optimize the design of more traditional means, can reduce the cost; no need accessories; prior to welding only need very simple standard working material optimization : Social and welding a wide range of variety of materials can accept different types of materials, welding automation of production process: all the process parameters and electrical parameters. green laser pointer is for the customer to use as the laser indication tool.
It can be easily carried out measurement control and testing in other words, electron beam welding it depth is relatively deep, laser welding is 15mm maximum depth of electron beam welding can reach 95mm or larger, depending on the circumstances. 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. The free-electron laser (Free-Electron Laser, referred to as FEL) is a completely new type of free electrons as the working substance of a coherent light source.
