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.
