Abstract:
A welding machine, preferably of the flash butt welding type, designed to facilitate maintenance of the clamping means (3, 4, 6, 7), e.g. clamps, of the two longitudinal metal products to be welded. Advantageously, a first structure (2), provided with first clamping means (3, 4), and a second structure (5), provided with second clamping means (6, 7), are supported in a first part (10) of the carriage (1) delimited by a first beam (9) and a second beam (8) of the carriage (1) parallel to the feeding direction (X), while at least one transformer (36) is fixed to the carriage (1) and supported in a second part (11) of the carriage (1), arranged laterally outside the first part (10).

Abstract:
A device (100) for covering the welding area for hot rolling lines consists of an outer container (1), a protective shield (2), a blade- holder (3) with scraping blades, and an actuator (9). Protection occurs by linearly sliding the protective shield (2) outside the outer container (1) up to minimizing the gaps with the billets. The cleaning occurs at the same time as the return to the rest position : the scraping blades, which are integral with the container (1) and are installed in contact with the inner surface of the protective shield (2), slide thereon during the raising, thus colliding with the deposits of solidified material and removing them. Completing the device (100) additionally is a small alternating linear motion of the protective shield (2) during operation to always keep the attachment area of the scraping blades clean, thus avoiding the need for excessive detachment forces at the beginning of the raising.

Abstract:
Method for manufacturing a bearing ring (14, 34, 36) from at least one steel bar (12) having ends. The method comprises the steps of forming said at least one steel bar (12) into at least one ring segment and flash butt welding the ends (12a, 12b) of said at least one ring segment to make a ring. The method also comprises the step of carburizing at least part (C) of a surface (12c, 12d) of said at least one steel bar (12) which is adjacent to said surface (12a, 12b) that is to be flash butt welded prior to said flash butt welding.
