Ordinary laser welding is also known as pulsed laser: mainly used for spot welding and seam welding of thin-walled metal materials within 1 m m thickness, the welding process belongs to the heat conduction type, that is, the laser radiation heats up the surface of the workpiece, and then spreads to the internal material through heat conduction, and by controlling the parameters of the laser pulse waveform, width, peak power, and repetition frequency, etc., the formation of a good connection between the workpieces. It has a large number of applications in the industries of 3C product shells, lithium batteries, electronic components, mold welding and so on. The biggest advantage of pulsed laser welding is that the overall temperature rise of the workpiece is very small, the heat-affected range is small, and the deformation of the workpiece is small.
Continuous laser welding most of the high-power lasers, power in 500 watts or more, generally more than 1mm plate should use this laser. Its welding mechanism is based on the small hole effect of deep fusion welding, depth to width ratio is large, can reach more than 5:1, welding speed, heat deformation is small. It has a wide range of applications in machinery, automobile, ship and other industries. There is also a part of the low-power continuous laser, power in the tens to hundreds of watts between them in the plastic welding and laser brazing these industries use more, Shenzhen Chaumi laser has pulsed laser laser marking machine, continuous laser welding machine have, free sampling, account on the contact
