| 摘要 |
This invention relates to a method and a device for igniting a gas planing process. The method is based on applying heat to a workpiece by means of a movable heat source, which in principle has a point effect so that the heated or molten portion of the workpiece forms a strip, which in principle extends perpendicularly to the flow direction of the planing oxygen. The device for carrying out the method comprises one or more planing burners and one or more movable ignition means so connected to the burner that the ignition means can move relative to the planing burner both in parallel with and perpendicularly to the planing direction and at the same time carry out the function of a heat source of in principle point shape, which preheats a strip-shaped zone on the surface of the workpiece and/or in addition to said preheating adds molten metal to said zone.
