Because of the small laser spot, high energy density and fast cutting speed, laser cutting can get better quality of ASTM A53 Gr. B steel pipe. Laser cutting incision is narrow, slit on both sides parallel and vertical to the surface, the dimensional accuracy of cutting parts can reach ±0.05mm.
Cutting surface is smooth and beautiful, the surface roughness is only dozens of microns, and even laser cutting can be used as a process, without mechanical processing, parts can be used directly.
After laser cutting of ASTM A53 Gr. B steel pipe, the width of the heat affected zone is very small, and the performance of the material near the slit is almost not affected, and the workpiece deformation is small, the cutting precision is high, the slit geometry is good, the slit cross section shape is relatively regular rectangular.
Due to the limitation of laser power and equipment volume, ASTM A53 Gr. B steel pipe laser cutting can only cut medium and small thickness of ASTM A53 Gr. B steel pipe, and with the increase of workpiece thickness, the cutting speed decreases obviously.
