Immersible system for excluding water for thermal welding process under water

摘要

The system has a heating source, a burner housing and an inlet for pressure gas. A protective gas nozzle (12) is mounted at the burner housing, and surrounds at least one section of the heating source. The protective gas nozzle has a distal end. A baffle plate, produced from an elastic heat resistant spring material, is arranged in a closed loop, and is carried by the distal end of the protective gas nozzle. The baffle plate is designed in the manner of a coiled spring (22), the ends of which are connected. The baffle plate has an elliptical cross section.
