PURPOSE:To tack weld web material and flange materials while the shapes of these materials are straightened and to manufacture the welded shapes with satisfactory assembling accuracy. CONSTITUTION:The web material W is raised up to the specified position by an elevating and lowering machine 11 and the flange materials FL and FR are pressed against the end faces of the web material W by rising machines 14L and 14R. The flange materials FL and FR are mounted on rising supporting bodies 18L and 18R to rise and fall in accordance with turning of arms 15L and 15R. Plural upper side pressure rollers 311, 312,..., 31n and lower side pressure roller 321, 322,..., 32n are opposed to both upper and lower surfaces of the web material W and pressure rollers 33L1, 33L2,..., 33Ln and 33R1, 33R2,..., 33Rn are opposed to the respective flange materials RL and RR along the longitudinal direction of the assembled web material W and flange materials FL and FR. While the shapes are straightened by these pressure rollers, the web material W and flange material FL and FR are tack welded by welding torches 34L and 34R.

2. Description of the Related Art Welded shaped steel is produced before the welding process by assembling a flasidy material or the like on a web material by a manual jig such as a crane or a clamp, temporarily attaching it by spot welding, and then performing main welding such as fillet welding. It is manufactured by correcting warpage and bending. At this time, most of the assembling of the web material and the flange material, the tack welding and the like are performed manually. Therefore, productivity is poor and work safety is also a problem.

As described above, in the manufacturing apparatus of the present invention, a plurality of pressure rolls and holding rolls are arranged on the flange material along the longitudinal direction of the web material and the flange material, and these pressure rollers are arranged. The web material and the flange material are fed into the temporary welding process while correcting and fixing the web material and the flange material with a roll and a holding roll. Therefore, the web material and the flange material are tack-welded with good assembling accuracy, and since no impact load is applied, the welding conditions at the tack-welding are stable. Further, the ascending operation of the web material and the erecting operation of the flange material in the assembling process are performed at the same time after the non-contact type sensor detects the member, so that the assembling process is efficiently performed without malfunction. In this way, when the web material and the flange material that have been tack welded to a good assembly shape are main welded, the shape correction work after the main welding is also reduced, and the welded shape steel with excellent welding strength is efficient. Manufactured to.
