Using closely focused ultrashort pulses, almost all transparent materials can be transmitted. Weldable materials include polymers, dielectrics and even ceramics. In this method, the two materials to be welded are placed closely together; The material placed on the top must be transparent to the laser, so that the laser can pass through the top material. Focus…
At present, there are two main methods for cutting metal plates: plasma cutting and laser cutting. Plasma cutting can be traced back to the 1950s, when it emerged as a substitute for flame cutting. The working principle of plasma cutting is: spray the overheated ionized gas (plasma) from the nozzle to the workpiece at high…
Compared with conventional welding methods, laser welding is a precision welding method with multiple functions, strong adaptability and high reliability, and is easy to realize automation. Due to the high power density of the laser and the low heat input during welding, on the basis of ensuring the penetration depth, the welding heat affected zone…
