Abstract
A welding machine, preferably of the flash butt welding type, designed to facilitate maintenance of the clamping means, e.g. clamps, of the two longitudinal metal products to be welded. Advantageously, a first structure, provided with first clamping means, and a second structure, provided with second clamping means, are supported in a first part of the carriage delimited by a first beam and a second beam of the carriage parallel to the feeding direction, while at least one transformer is fixed to the carriage and supported in a second part of the carriage, arranged laterally outside the first part.
Claims19
A welding machine, preferably of the flash welding type, to weld a tail of a first longitudinal metal product together with a head of a second longitudinal metal product along a feeding direction of said longitudinal metal products, the machine comprising a carriage adapted to slide along the feeding direction,
- said carriage supporting
- a first structure connected to said carriage;
- first clamping means, provided on said first structure, to clamp either the tail of the first longitudinal metal product or the head of the second longitudinal metal product;
- a second structure adapted to slide, with respect to both the first structure and the carriage, parallel to the feeding direction;
- second clamping means, provided on said second structure, to clamp either the head of the second longitudinal metal product or the tail of the first longitudinal metal product;
- at least one transformer provided with conductors connected to the first clamping means and to the second clamping means, respectively, to supply electric current to said tail and said head;
- wherein the first structure and the second structure are supported in a first part of the carriage delimited by a first beam and a second beam of the carriage that are parallel to the feeding direction, while the at least one transformer is fixed to the carriage and supported in a second part of the carriage, arranged laterally outside the first part.
