READ MOREWhat is the principle of using metallurgical nitrogen generator to reduce slag production?
In the metallurgical industry, processes such as welding, soldering and brazing are common methods for metal connection and repair. However, these processes are often accompanied by the generation of slag, which not only affects the quality of the welded joint, but may also cause damage to the equipment. In order to reduce the generation of slag, metallurgical nitrogen generators play a key role. Next, let's explore the principle of using metallurgical nitrogen generators to reduce slag generation.
During welding and heat treatment, the metal surface easily reacts with oxygen in the air to form oxides. These oxides will mix with the welding material during welding to form slag that is difficult to remove. The presence of slag will not only reduce the strength and sealing of the welded joint, but may also cause welding defects such as pores and slag inclusions. Therefore, controlling the oxygen content during welding is the key to reducing slag generation.
Metallurgical nitrogen generators provide a pure nitrogen environment for welding and heat treatment processes by separating nitrogen from the air. Nitrogen is an inert gas that does not chemically react with metals, thereby avoiding oxidation of the metal surface. During welding and heat treatment, using nitrogen generated by a nitrogen generator to purge the welding area can effectively remove oxygen and other impurities in the air, making the welding area oxygen-free or oxygen-reduced.
When the welding area is in an oxygen-free state, oxides will not form on the metal surface, thus avoiding the generation of slag. In addition, nitrogen purging can also help remove impurities and residues on the surface of the welding area, further improving the quality of the welded joint.
In addition to reducing slag generation, there are many other benefits to using a metallurgical nitrogen generator. For example, nitrogen purging can reduce spatter generated during welding and reduce damage to workers and equipment. At the same time, nitrogen can also increase the cooling rate of the welded joint, thereby improving the organization and performance of the welded joint.
