Cutting & Welding Gases

Supporting all welding techniques with the full selection of welding, shielding and laser gases and mixtures along with reliable supply solutions and robust welding equipment.

Welding is an essential process in just about every industry. Various techniques are used to melt and fuse metals, steels and alloys.

Arc welding uses the heat generated by an electric arc struck between an electrode and a workpiece to melt and fuse metal in the joint area.

This is the most common fusion-based joining method used in industry today.

 

However, laser welding is growing in popularity in the automotive industry in particular and in other sectors such as microelectronics and shipbuilding. This involves focusing a laser beam onto a workpiece by a set of mirrors. When the laser beam is moved relative to the workpiece, the energy of the focused laser beam melts the metal so that a joint is formed.

In all welding processes, the shielding and process gases, their exact compositions and their purity levels play a key role in influencing weld quality and productivity.

Oxygen, nitrogen, argon and carbon dioxide are standard or bulk gases that are used in process and manufacturing industry today. However, in many gas solutions or applications gas mixtures are commonly used. With these premium gases like MISON® shielding gas you can increase the quality or your product, the productivity of your labour and the profitability of your business.

For any welding process, it is important to choose the right shielding gas. AGA provides an extensive shielding gas range to meet all requirements.
