Patent number: 10486271Abstract: A welding apparatus having a welding tool and a weld cooling apparatus for forced cooling of the weld zone. The welding tool has a welding nozzle with a longitudinal axis, and the weld cooling apparatus uses a source of CO2 as the coolant. A coolant delivery conduit is arranged to move with the welding tool and has a first tube with a longitudinal axis that extends alongside the welding tool, and a second tube with a longitudinal axis extending downwardly and away from the welding tool. A coolant nozzle is located at the end of the second tube to eject coolant at the weld zone. The coolant nozzle outlet is spaced from the workpiece and arranged to direct a jet of coolant behind the welding tool onto the weld zone at least 10 mm from the longitudinal axis of the first tube.Type: GrantFiled: June 22, 2015Date of Patent: November 26, 2019Assignee: LINDE AKTIENGESELLSCHAFTInventors: Walter Mark Veldsman, Roger O'Brien
