    • An apparatus for in-line ERW welding of hollow flange steel members in a cold forming mill comprises a seam roll stand (60) rotatably supporting at least one seam roll (68) adapted in use to guide a free edge (34a,34b) of a contoured metal strip (30) into linear alignment with a predetermined weld axis spaced from said free edge on a surface of the metal strip. The apparatus also includes a weld box stand (61) supporting at least one pair of squeeze rolls (84a,84b), in use, adapted to urge the free edge (34a,34b) when heated to a predetermined temperature into fused engagement with a correspondingly heated weld axis on the surface of the strip (30). The squeeze rolls (84a,84b) co-operate to guide the free edge through a predetermined linear trajectory substantially along an incidence axis of a subsequent weld junction between the free edge (34a,34b) and the surface of the metal strip (30) whereby energy imparted to the cold formed member is focussed by a proximity effect along the predetermined weld axis. ® KIPO & WIPO 2007
    • 一种用于在冷成型轧机中的中空法兰钢构件的在线ERW焊接的设备包括:可旋转地支撑至少一个接缝辊(68)的接缝辊架(60),其适于在使用中引导自由边缘(34a,34b) 与金属带的表面上的所述自由边缘间隔开的预定焊接轴线线对齐的成形金属条(30)。 该设备还包括一个焊接支架(61),其支撑至少一对挤压辊(84a,84b),其在使用中适于在加热到预定温度时将自由边缘(34a,34b)推压到与 条带(30)的表面上相应加热的焊接轴线。 挤压辊(84a,84b)协作以基本沿着自由边缘(34a,34b)和金属条(30)的表面之间的后续焊接接头的入射轴线引导自由边缘穿过预定的线性轨迹, 由此通过沿预定焊接轴线的邻近效应聚焦到冷成形构件的能量。 ®KIPO&WIPO 2007
