Examination and a laser cutter blade welding, inspection of weld strength: with green silicon carbide grinding wheel grinding behind a winnower knife, check the solder layer thickness, thickness requirements in 0. Below 15 mm. Tip bearing bottom place cannot have porosity and insufficient solder, solder incompletely filled the weld should be not more than 10% of the weld length. If there is a hole, can make the blade when cutting off. Second, check the position of the blade in the knife trough: such as blade dislocation and drooping over the provisions of the technical conditions should be heavy weld cutter blade. 3, check the welding strength: with wooden hammer or copper hammer at a moderate force on the blade, or in the I hammer with strong knock tool rod, then the blade don't fall off as a qualified from the groove. Check the blade welding strength, not one by one check, also USES selective examination method. Four, check the blade smoothness: if there are obvious pits on the blade, blade overheating deformation, should burn under heavy welding new blades. 5, check the crack: blades after kerosene cleaning, if the crack in the blade. Kerosene and infiltrate the crack and appear black line, can be observed with the naked eye. 10 - is also available 40 times the magnifying glass to observe.
