What is an arc:
fed by the caster welding power supply.The phenomenon of a strong and long-lasting gas discharge between the two poles is called an electric arc.
What is a protective gas:
Caster welding used to protect the molten metal droplets and the molten pool from outside harmful gases (hydrogen, oxygen, nitrogen) invasion of the gas called shielding gas.
Caster welding technology:
Caster welding technology covers a variety of caster welding methods, caster welding materials, caster welding process and caster welding equipment and its basic theory of the general term.
Caster welding process:
Caster welding process refers to a set of process procedures and its technical provisions in the caster welding process.It includes caster welding methods, pre-welding preparation processing, assembly, caster welding materials, caster welding equipment, caster welding sequence, caster welding operation, caster welding process parameters and post-welding treatment.
Caster welding method:
Brazing is a type of brazing that uses a metallic material with a lower melting point than that of the workpiece as the brazing material.Heating the workpiece and brazing material to a temperature above the melting point of the brazing material but below the melting point of the workpiece.Utilizing liquid brazing material to wet the workpiece, the filling of interface gaps and interatomic diffusion with the workpiece.Thus, the method of welding is realized.
Welding technology is mainly applied to the base metal.Commonly used are arc welding, argon arc welding, CO2 shielded welding, oxygen – acetylene welding, laser welding, electric slag pressure welding and many others.In addition.Non-metallic materials such as plastics can also be welded.There are numerous methods of metal welding.Over 40 species.There are three main categories: fusion welding, pressure welding and brazing.
Fusion welding is a welding process in which the workpiece interface is heated to a molten state.A method of completing a weld without applying pressure.When fusion welding, the The heat source rapidly heats and melts the interface between the two workpieces to be welded.Formation of a molten pool.The molten pool moves forward with the heat source, the After cooling, a continuous weld is formed and the two workpieces are joined as one.Pressure welding, on the other hand, is under pressurized conditions.enabling interatomic bonding of the two workpieces in the solid state.Also known as solid state welding.The commonly used press weld process is resistance butt welding, the As the current passes through the connecting ends of the two workpieces, the where the temperature rises due to high resistance.When heated to a plastic state, the Connected as a single unit under axial pressure.
Welds:
The joint formed when a caster is welded to connect two connected bodies is called a weld.Both sides of the weld will be subjected to weld heat during welding.while undergoing changes in organization and properties.This area is known as the heat affected zone.
