Laser cutting screen welding technology, compared with other welding methods, do not need electrodes and filling material, can achieve localized heating, to ensure high speed heating.Since there is no mechanical contact during welding, the possibility of extraneous materials falling into the parts to be welded is eliminated, and the welding area is almost free from contamination.Can be high melting point, refractory metal or different thickness, different metal materials for welding.For example, by using laser machining to weld diamond circular saw blade and drill bit, the bonding strength between matrix and diamond cutter can be improved, and the geometric accuracy is high, which can be applied to dry cutting, and the phenomenon of cutter tooth shedding can be overcome.
Laser cutting processing screen cutting technology, compared with other cutting process, has the advantages of high speed, high precision and high adaptability, thin slit, small heat affected zone (small deformation), good cutting end quality, cutting no noise, weld area organization and performance close to the base metal, etc.And, processing only simple fixture, no die, can replace the use of complex die punching cutting processing method, can greatly shorten the production cycle, reduce production costs.For example, the oil screen can be slit;It can cut the metal pipe and plate, and reduce the serious noise pollution caused by the diamond circular saw blade in the working process by using the laser machining and slitting technology
Laser cutting machine technology has obvious huge advantages, but as a high-tech equipment, to use the laser cutting machine to achieve the ideal cutting effect, but also must master its processing technical parameters and operation process.Especially in the process of metal laser cutting, to choose the right cutting speed, when the laser cutting speed is too slow, and will cause: caused by melting, cutting surface is rough.Stitches widen and dissolve entirely at sharp corners.Affect cutting efficiency.When the laser cutting speed is too fast, it will cause the following bad results: method cutting, spark spray;Causing the cutting surface to show oblique lines, and the lower half of the melt stains;The whole section is thick, but no stain is produced.
