These welding jaws are operated by arms (13) engaging on the opposite mould half, so that during closure of the mould halves the welding jaws carry out the desired movement.

The casing (20) is composed of first and second casing halves (21, 22) joined together by welding.

The welding may include: spin welding, hot plate welding, vibration welding, and ultrasonic welding.

When the vanes have been mounted in place on the tube halves (10), the vane/tube-half assemblies are welded together along their longitudinal edges (27) to form complete tubes.

In the welding/cutting device (30), the welding is flat welding.

The ignited weld ignition material initiates exothermic based welding of a weld material.

In order to achieve welds in the centre part of the container, the mould device comprises bottom mould halves (10), two hinged welding jaws (12) always being provided in each mould half.
