When being compared with laser pointer

The reason of the same visual effect of laser pointer will be explained 
Their use be limited accordingly. The human cost depends on the welding speed, hourly wages and total working hours (including welding and subsequent processing). Raw material costs including the purchase of the parent metal and weld filler material, the protection of the cost of gas. The energy cost depends on arc time and welding energy needs. For manual welding, labor costs are often a large part of the total cost. Therefore, the lower the cost of manual welding is often focused on reducing the time of the welding operation, effective way to improve the welding speed, to optimize the welding parameters. After welding slag removal is also a time-consuming and laborious work. Therefore, by reducing the welding slag can improve the safety, environmental protection, and reduce costs, improve the welding quality. Of course, the manufacture and assembly of laser pointer should be guaranteed at the same time. 
Dedicated lathe the processability ф1000m length 14m less than the parts. All structural parts using CNC cutting cutting edge milling machine to be assembled structures reinforcement to the underside of the knife check to increase the contact surface of the assembled parts to ensure a degree of parallelism, an increase of the rigidity and strength of the overall structure. Hydraulic support structure used in all our company developed a special six-axis boring machine and four-axis gantry boring machine for the overall processing and reliable way to ensure the structural hole between the position requirements and consistency of the structure size to solve the hole axial and position tolerance requirements of the problem, ensure R0.5 and R1mm, concentricity requirements, completely solved the structure of the assembly quality and interchangeability requirements. It is to guide the production of the new type of laser pointer .When being compared with laser pointer
The ultrasonic welding used in the manufacture of copper or aluminum to the electrical interface is also more common in the welding of composite materials. Another common solid-state welding process is explosion welding (Explosion welding), and its principle is to form a connection under high temperature and high pressure material produced in the explosion. The impact of the explosion makes the material a short period of time to show plasticity to form the solder joint, this process produces only a small amount of heat. This process is usually used to connect the welding of different materials, such as aluminum components connected to the hull or composite board.
