To provide an instantaneous thermochemical start on the surface as a metal workpiece to be gas planed, a surface area of the workpiece being brought to its ignition temperature by a jet of oxygen directed towards the surface and a molten bath being formed and spread to a uniform surface. that one: (a) causes relative movement between the workpiece and the stream as oxygen which forms a stream as planing oxygen, and at the same time dammed 1. slAr Atminstone en laserstrAle emot arbetsytan for att Astadkomma en varmd uSg as onskad lAngd tsars Over ytan, relatiut till dens rorelseriktning, varvid den varmda vagen Istadkommes medelst laserstrAlen, som vArmer en serie as punkter pi ytan till deras syreantandningstemperatur, och1. At least one laser beam strikes the work surface to produce a hot useless unwanted length across the surface, relative to its direction of motion, the heated wave being produced by the laser beam, which heats a series of points on the surface to their oxygen ignition temperature, and 2. slAr en strom as hyulande syre emot den varmda vagen, varigenom ett Ogonblickligt gashyvlingssnitt borjar utefter sages, och (b) fortsatter strAkmen as hyvlandl..syre till dess den Onskade langden as snittAstadkommit2. a current as a howling oxygen strikes the heated wave, whereby an instantaneous gas planing cut begins along the saw, and (b) the current continues as a hyvlandl..six until the desired length as a cut is achieved.
