CA 2386340

Portable machine for gas pressure butt-welding of oil well strings and other steel bars in the field. The machine uses a screw and a high torque tool to develop the pressure necessary for welding, instead of a hydraulic system as most similar machines do, thus making the machine lighter and cheaper and lowering its maintenance requirements. The machine also incorporates a means of adjusting the concentricity of two welded rods of different diameters, a saw for cutting the ends of the rods to be welded, and a simple double-hinged support for the burner.

Machine portative pour le soudage bout à bout au gaz par pression de colonnes de puits de pétrole et d'autres barres d'acier utilisées dans le domaine. La machine utilise une vis et un générateur de couple puissant pour développer la pression nécessaire pour le soudage, au lieu d'un système hydraulique comme la plupart des machines similaires, ce qui rend la machine plus légère et moins coûteuse et réduit ses besoins d'entretien. La machine intègre également un moyen pour ajuster la concentricité de deux barres soudées de différents diamètres, une scie pour couper les extrémités des barres à souder, et un simple support à double charnière pour le brûleur.
