摘要： A system and method of forming a continuous strip from a plurality of strips, each strip having a leading end and a trailing end. Embodiments can include a forming apparatus that chamfers at least one of the leading and trailing ends of each strip. The chamfered trailing ends may then be positioned against chamfered leading ends of successive ones of the plurality of strips. Once a leading end and a trailing end are positioned against one another, a first welding apparatus may weld on a first side, from above, the trailing and leading ends positioned against each other to form weld joints. Once at least two strips have been welded together, the strips can constitute the continuous strip. An inverting apparatus can then invert the continuous strip and weld joints. The inversion of the weld joints can be done so as not to create a reverse bend in the continuous strip. A second welding apparatus can then weld on a second side opposite the first side, from above, the inverted weld joints to form weld junctions. A pipe forming apparatus can form a pipe using the continuous strip, wherein the successively welded-together strips can be continuously or semi-continuously supplied to the pipe forming apparatus to form the pipe.
摘要翻译：一种从多个条带形成连续条带的系统和方法，每个条带具有前端和后端。实施例可以包括对每个条带的前端和后端中的至少一个进行倒角的成形装置。倒角的后端然后可以被定位成抵靠多个条中的连续的条的倒角的前端。一旦前端和后端彼此相对定位，则第一焊接设备可以在第一侧从上方焊接相对于彼此定位的后端和前端以形成焊接接头。一旦至少两条条被焊接在一起，条带可以构成连续条带。然后，翻转装置可以反转连续的条带和焊接接头。可以进行焊接接头的反转，以免在连续条带中产生反向弯曲。然后，第二焊接设备可以在与第一侧相反的第二侧上，从上方焊接在倒置的焊接接头上，以形成焊接接头。管形成装置可以使用连续条形成管，其中连续焊接在一起的条可以连续或半连续地供应到管形成装置以形成管。
