What is the difference between arc welding and argon gas welding

Arc welding and argon gas welding are two different types of welding that use different methods and materials to join metal together.

Arc welding uses an electric arc to create heat and melt the metal, while argon gas welding uses an inert gas, typically argon, to shield the weld area.

Arc welding is more common and versatile, and can be used on a wide range of metal thicknesses and types. Argon gas welding is typically used for thinner metals and for welding aluminum and other non-ferrous metals. Arc welding also typically requires more skill and experience than argon gas welding, as the welder needs to control the heat and the welding rod to create a consistent and quality weld.

  1. The difference between concepts

Argon arc welding is a kind of welding technology using argon as a shielding gas. Also known as argon gas-shielded welding. It is to pass argon shielding gas around the arc welding to isolate the air outside the welding area and prevent the oxidation of the welding area.

Arc welding is commonly referred to as electric welding. It uses the coated welding rod as the electrode and filler metal. The arc burns between the end of the welding rod and the surface of the workpiece to be welded.

2. Differences in the welding process

Arc welding process: under the action of arc heat, on the one hand, the coating can produce gas to protect the arc, on the other hand, it can produce slag to cover the surface of the molten pool to prevent the interaction between the molten metal and the surrounding gas. The more important role of slag is to produce a physical and chemical reaction with molten metal or to add alloy elements to improve the properties of weld metal.

Argon arc welding process: using argon to protect the metal welding material, through high current to make the welding material melt into liquid on the substrate to form a molten pool, so that the metal to be welded and welding material to achieve a metallurgical combination of welding technology, due to the continuous supply of argon in high-temperature fusion welding, the welding material can not contact with oxygen in the air, to prevent the oxidation of the welding material, so it can be welded stainless Steel and iron hardware.
