The welded connection between the workpiece can be a variety of joint form

green laser pointer needs the preheating
They have co-operation with companies such as Rofin Sinar. Using a CO2 laser-based remote welding equipment, the use of the scanning lens to the reflected beam high-speed welding body parts more than one welding position. In a typical part of the Fiat Marea models, remote CO2 laser welding has also been used to replace resistance spot welding, in order to eliminate the cost by the adhesive on the rear tailgate. In this application, the total laser seam welding time is 5s. 43 laser weld in the welding of the door frame of the model, only 30s can be done to replace the traditional resistance spot welding. In this application, the repeatability of positioning time fell as much as 94%.
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. The advice and suggestion of green laser pointer  is from the technical personnel.Slow start of  green laser pointer is due to the ultra low ambient temperature
Other solid-state welding processes, including extrusion welding (Co-extrusion welding), cold welding (Cold welding), diffusion welding (the Diffusion welding), Friction Welding (Friction welding) (Friction Stir Welding (Friction stir welding), high frequency welding ( High) frequency welding), hot pressing, welding (Hot pressure welding), induction welding (Induction is welding), hot rolled welded (Roll welding) [25]. The connector type common type of welded joints: (1) butt joints; V-shaped butt joint; lap joint; T-shaped connector. The welded connection between the workpiece can be a variety of joint form.
