Abstract: Twin roll caster produces cast steel strip that passes in a transit path through pinch roll stand and optional hot rolling mill and runout table to a coiling station which has a pair of switchable coilers. A strip shear located in advance of the coiling station is operable to sever strip into discrete lengths which can be diverted by setting deflectors to allow the severed lengths to pass across a runout table to a scrap bin. The strip may be thus severed and diverted to scrap on development of strip defects or malfunctioning of equipment without stopping continuous casting and the strip redirected to the coiling station when the problem is rectified.

Abstract: Process for manufacturing a welded pipe from a metal strip having two longitudinal edges approximately parallel to each other, which are brought together so as to come approximately into contact with each other and thus form an unwelded pre-tube, the pre-tube then being welded in order to join the edges together. The two edges are welded together to obtain a welded metal pipe by using, approximately simultaneously, at least one laser beam and at least one electric arc, that is to say using a hybrid arc/laser, preferably plasma/laser, welding process. This process can be used to produce weld seams of rectilinear, helicoidal or spiraled shape.
