Gas-shielded welding

Gas-shielded welding is a common process in metalworking that is used to create strong and durable joints between metal parts. In this process, a shielding gas is used to protect the weld seam from atmospheric influences and to ensure a high-quality welded joint.

The process of gas-shielded welding begins with the preparation of the metal parts to be joined. These are thoroughly cleaned to remove oxidation and impurities that could affect the quality of the welded joint. The parts are then fixed in the correct position to achieve the desired joint.

During the actual welding process, an arc is created between an electrode and the metal parts to be joined. At the same time, a shielding gas is emitted around the arc. This shielding gas, which is often argon or helium, is used to protect the welding zone from atmospheric contamination by displacing oxygen and nitrogen.

The shielding gas flow can vary depending on the requirements of the application. It can be used both as a pure gas and as a mixture of different gases to achieve specific welding properties, such as improved penetration, higher welding speeds or better protection performance on different materials.

Gas-shielded welding offers a number of advantages, including high welding speed, good weld quality and the ability to join a variety of materials. It is used in various industries, including automotive, aerospace, marine and offshore, construction and many other areas where high quality welded joints are required.
