- What is a welding machine?
Welding machine is the use of various alloys (solder) to connect the metal parts to the process. The melting point of the mixture is less than that of the welding material, so this part will eliminate welding through contact between the molecules on the surface without melting.
Welding machine can be divided into soft welding and hard welding, soft welding temperature below 450 ،, hard welding more than 450. Hard welding is commonly used for silver, gold, steel, copper and other metals, the welding approach is stronger than soft welding, embroidery strength for soft welding of 20-30 times. Two types of heat connections are commonly used in terms of welding, as both are inscribed in thin welds of clean and close solid metal surfaces of two devices that are both durable.
The welding machine ensures the continuity of the metal. On the one hand, two metals are connected to each other by bolts or physical attachments, in which a strong metal is fully shown, but this connection is unconnected, and sometimes the metal surface, if oxide insulation film is present So, right or wrong physical contact. Another drawback of mechanical coupling and welding is that the contact surface continues to oxidize and cause resistance. In addition, vibration and other mechanical shock can also find joints. Welding is just to eliminate these problems,
The welding site does not have relative movement, the contact surface is not oxidized, the process of continuous processing is to be followed. Welding is the process of fusion between two metals, solder in the melting state, will impose some metals in contact with the metal surface, can not dissolve the oxide film with the thin layer of welded, remove the flow Used to. This layer of oxide film. The welding process usually involves:
1) Melting flow, thus removing the oxide film on the metal surface;
2) to suspend the instability between them and the light flow of the surface to melt the solder;
3) To wash some metal associated with some matching;
4) Finish melting of metal with solid and alloy.
