How to reduce the cutting burr of ASTM A588 Grade C weathering steel plate

1. First of all, check whether there is a problem with the laser output, and whether the light spot is very round (the transverse distribution of the laser energy is uniform, and the cutting quality of the ASTM A588 Grade C weathering steel plate is good)

2. Before cutting the ASTM A588 Grade C weathering steel plate, check whether the lens in the process of laser transmission is dirty, or whether the lens is dirty, and whether the lens has small cracks that are not easy to be found by the naked eye, which will affect the transmission of the laser.

3. The following is the adjustment of process parameters. If it is a ASTM A588 Grade C weathering steel plate after laser cutting the burr is a certain hardness, it is difficult to remove, very time-consuming, but also affect the appearance. It is better to deal with the root cause.

First of all, the purity of the auxiliary gas for ASTM A588 Grade C weathering steel plate cutting should be high, and then the cutting parameters should be adjusted to the best, the focal length, cutting speed, power, running time and so on, which should be adjusted several times.
