Abstract
PURPOSE:To simplify the apparatus and speeding up the time of operation, by changing successively the applied energy density and location of laser ray emitted from one set of laser ray generating equipment by making use of an optical instrument. CONSTITUTION:The laser ray is applied onto the steel plate, travelling reflected at the concave mirror 7 and the end of the coil 1 is then cut off. The section being cut is made smooth by means of O2 gas blasting from the nozzle 13. Next, the end of the coil 2 is introduced and set to an appropriate position and cut in the direction of plate width by applying laser ray via the mirror 7. The coil 2 being cut is butted against the coil 1 and welded in the direction of plate width by laser ray. In the welding procedure, Ar or He gas is supplied from the nozzle 13 to avoid the chance of oxidation. Then, the mirror 7 is relocated and laser ray is further applied to the coil so as to cut off the end of coil in an arch shape. At that time, O2 gas is flown out from the nozzle 13, and aser ray is further applied to the weld bead and its both sides via the mirror 11. Soon after the application of laser ray, the welded part and heat effected zone are annealed by natural cooling.
