- the degree of the thermal influence received from the welding point can be, for example, the amount of heat received by the rollers 31 and 32 from the heat source per predetermined time at the position during laser welding.
- an area where the degree of thermal influence exceeds a predetermined value may be an area where the rollers 31, 32 exceed the allowable temperature.
- the web material 4 is held by the belt-type web holding device 20 on the upstream side, and the web material 4 is held by the roller-type web material holding device 30 on the downstream side. It is also possible to omit the web holding device 20 and hold the web material 4 only with the roller web holding device 30 on the upstream side or the downstream side.
- the two laser heads 201 and 202 are both disposed on the upper surface side of the web material 4 in FIG. 1, the two laser heads may be disposed on different surface sides of the web material.
- first surface side roller 31 and the second surface side roller 32 are the same when viewed from above, both the first surface side roller 31 and the second surface side roller 32 are viewed from above The positions may be different.
- the axial position of the shaft 36 is fixed relative to the support frame 33.
- the axial position of 36 may be adjustable.
- a hole 52 having a female screw from the outside is formed up to the shaft 36 penetrating in the horizontal direction orthogonal to the transport direction with respect to the support frame 33, and a bolt 51 is screwed into this hole 52;
- the axial position of the shaft 36 may be fixed.
- Such a configuration is convenient when the two rollers 31 are disposed at an asymmetric position with respect to the center line 7.
- the second support frame 34 and the second surface roller 32 can be configured in the same manner.
- the present invention can be applied to, for example, a manufacturing apparatus and a manufacturing method for manufacturing a welded H-shaped steel.

Abstract
Description
既述の実施形態では、第1面側ローラ31および第2面側ローラ32のフランジ材2,3に対向する側端部が、溶接点5,6からのスパッタの飛散量の度合いが所定値(所定値=0)を超える領域の境界に沿って配置されていたが、前記境界に代えて、溶接点5,6から受ける熱影響の度合いが所定値を超える領域の境界に沿って第1面側ローラ31および第2面側ローラ32のフランジ材2,3に対向する側端部を配置してもよい。ここで、溶接点から受ける熱影響の度合いは、例えばレーザ溶接中にローラ31、32がその位置で所定時間当たりに熱源から受ける熱量とすることができる。例えば、前記熱影響の度合いが所定値を超える領域をローラ31,32がその許容温度を超える領域とすることができる。
