2、 Professional interpretation
By heating or pressurizing, or both, and with or without filler materials, the welding refers to a processing method in which the welded parts (the same or different materials) achieve the combination between atoms or molecules to form a permanent connection
A welding method for melting the base metal to be welded to form a weld. Because the welded parts are closely attached together, under the action of temperature field, gravity, etc., the molten liquid melted by the two fusion welding refers to the workpiece will be mixed. After the temperature decreases, the melting part condenses, and the two workpieces are firmly welded together to complete the welding (unless otherwise specified in this listing recommendation, “welding” refers to fusion welding)
The abbreviation of fusion welding materials refers to the general name of materials consumed in fusion welding. Fusion welding materials refer to, for example, welding rods, welding wires, metal powders, fluxes, gases, etc. (unless otherwise specified in this listing recommendation, “welding materials” refer to fusion welding materials)
Welding wire refers to the welding material used as filler metal or conductive wire at the same time
Electrode refers to the coated melting electrode for manual arc welding, which melts the metal strip filled in the joint of the welded workpiece during gas welding or electric welding
Flux refers to a granular material that can melt to form slag and gas during welding and play a role in protecting and metallurgical treatment of molten metal
Welding strip refers to the welding strip, which is not only used as filler metal but also conducts current. It is generally in coil shape and is usually used for submerged arc welding and electroslag welding
A wire drawn directly from a solid wire
Flux cored wire refers to a kind of welding wire made by rolling thin steel strip into a circular steel pipe and filling it with a certain amount of powder
Submerged arc welding wire refers to a kind of welding wire with high welding efficiency, which is used in conjunction with flux and the welding arc burns in the welding interior
Wire rod, also known as wire rod, usually refers to small-diameter round steel in coils
Submerged arc welding refers to a method in which the arc burns under the flux layer for welding. Submerged arc welding wire and flux are used together
Electroslag welding refers to a welding method that uses the resistance heat generated by the current passing through the slag as the heat source to melt the filler metal and the base metal and form a firm connection between metal atoms after solidification
Gas shielded welding refers to arc welding that uses gas as arc medium and protects arc and welding area
Note: there are differences in the mantissa of the sum of partial totals and itemized values in this listing recommendation letter. These differences are caused by rounding
