Welding technology

For high strength in your joint

Cylinder pressure regulator with pressure gauge

Welding technology produces inseparable, firmly bonded connections between metal or thermoplastic components. Welding involves melting components at their joint by using heat and/or force and joining them together during solidification. In many welding processes, both the melting and the joining of the components is done by applying force through welding equipment or welding machines. Compared to other types of connections, welded joints feature high strength.

Welding processes are divided into joint welding and build-up welding.
Joint welding:The joining of parts
Build-up welding:The coating of a part by welding

The physical welding process is divided into two sections: In fusion welding, the molten mass is locally limited. No force is applied here. During this process, the base materials exceed their liquidus temperature. Fusion welding joins all materials that are transferable in the molten phase. A welding wire is often introduced. In pressure welding, the materials to be joined are brought to the welding temperature by different energy forms. The materials are firmly bonded together by applying force. A welding wire or similar welding consumable is not used in this case. In pressure welding, the materials are welded together with different melting points. The parts are joined together by applying a large force.

RIEGLER flange pressure controllers, also known as pressure regulators, extract compressed gases from gas cylinders. These gas cylinders are used for welding, cutting or similar processes. We supply flange pressure controllers according to DIN EN ISO 2503 for non-flammable and flammable gases up to 200 bar and 300 bar. All flange pressure controllers are equipped with a pressure gauge for displaying the cylinder contents and the working pressure. Our online shop also offers controllers with flow meter. Our flange pressure controllers (pressure regulators) can be used for oxygen, compressed air, nitrogen, carbon dioxide, argon, helium, acetylene, hydrogen, methane, fluorescent gas and natural gas.
