Abstract

The present invention relates to a trailing nozzle device (1) for a welding torch (2) for covering a weld pool with a shielding gas, wherein the trailing nozzle device (1) comprises a trailing nozzle body (3) being configured to be mounted to the welding torch (2), wherein a shielding gas is ejectable onto a weld pool generated by the welding torch (2) via the trailing nozzle body (3), wherein the trailing nozzle body (3) comprises multiple segments (31, 32, 33, 34) extending side by side along an end section (2a) of the welding torch (2) in a circumferential direction of the trailing nozzle body (30) when the trailing nozzle body (3) is mounted to the welding torch (2), and wherein the trailing nozzle device (1) is designed to feed the segments (31, 32, 33, 34) with a shielding gas so that a flow rate of the shielding gas ejected through the respective segment (31, 32, 33, 34) can be controlled for each segment (31, 32, 33, 34) individually.
