Abstract: This method is suitable for the multi-layer arc welding of ferritic steels and for the subsequent heat treatment of the weld, especially in the case of large workpiece thicknesses and corresponding volumes. The reheating to just above the Ac3 transformation point, which serves to improve the structure, is limited essentially to the region of the weld bead applied last in each case and to the heat-affected zone adjacent to it. The heat energy introduced by the welding can be used to a great extent if the reheating is performed immediately following the completion of the transformation due to the welding heat. The subsequent heat treatment is expediently followed by cooling of the weld seam, it being possible to match the type of cooling to the requirements of the individual case. Downstream of the arc welding head (19), the apparatus has an inductor coil (3) and a multiple cooling jet (16). Arranged in the rear third of the line of heating influence (8) of the inductor coil (3) is a pyrometric temperature-measuring head (12). <IMAGE>

Also provided is a process for preparing these polyisocyanates which comprises reacting about 10 to 30 mol % of the isocyanate groups of an organic polyisocyanate with reaction products which have (i) alcoholic hydroxyl groups and (ii) structural units of the formula, -O-CO-NH-NH-CO-O-, and/or of the formula H2N-NH-CO-O-, with the formation of urethane groups and optionally groups corresponding to the formula, -NH-NH-CO-O-, and reacting about 50 to 90 mol % of the isocyanate groups of the organic polyisocyanate with a blocking agent. The reaction products containing alcoholic hydroxyl groups are obtained by reacting 1 mol of hydrazine or of hydrazine hydrate with about 1 to 2 mols of a cyclic carbonate. A final object of the present invention is the use of the new lacquer polyisocyanates as the isocyanate component in thermosetting, two-component polyurethane lacquers.
