The analysis of the laser cutting machine laser power

by：Transon 2020-10-28

In a laser cutting machine laser welding laser energy density threshold, lower than this value, penetration is very shallow, once reach or exceed this value, the penetration will be greatly improved. Only when the workpiece on the laser power density exceeds the threshold, Related to the material) , plasma can produce, in a sign of deep penetration stability. Only if the laser power is lower than the threshold, the workpiece surface melting, which is welded with stable heat conduction model. And when the laser power density in a hole near the critical condition of formation, deep penetration and conduction welding alternates, become unstable welding process, depth of molten lead to more volatile. Deep penetration laser, laser power and control the penetration depth and welding speed. Welding penetration is directly related to beam power density, and is a function of incident beam power and the beam focal spot. In general, to a certain diameter of laser beam, beam power increase as the penetration increases. This article reprinted from laser cutting machine
