Abstract

PURPOSE:To prevent the bucking and transverse deviation in the weld zones of a web material in the stage of producing welded H-beam through resistance welding of flange materials to both end parts of the web material by supporting guiding pltes for supporting the web material on both side faces of the web material through face contact. CONSTITUTION:In the stage of producing welded H-beam 1 by resistance welding of upper, lower flange materials 2, 2 and a web material 4, a welding ancillary device is constituted of upper, lower press contact rolls 3, 3, which support the material 2, 2 from top and bottom and guiding plates 5, 5 which support the materal 4 from the right and left. Here, the plates 5, 5 are mounted to brackest 6, 6 and are pressed to the material 4 approximately over the entire part thereof by means of cylinders 8, 8. Electricity is conducted from electrodes 7 and the materials are welded by resistance heat. Since the plates 5, 5 are exposed to friction, temp., pressure, magnetism and electric current for a long time during the welding work, the plates made of ceramics are used for these plates, so that the buckling and transverse deviation of the weld zones of the web material 4 and the degradation in the yield of products are prevented.
