Shaker from the screen frame, hollow grid, vibrating body, bottom tube and other components. The multi-component materials of stainless steel. In various parts of the manufacturing and welding process, welding technology was an important role in Chapter. TIG arc welding technology is in general based on the principle of using argon gas welding of  stainless steel welding wires  protection, through the vibrating screen by the screen frame, hollow grid, vibrating body, the bottom tube and other components. The multi-component materials of stainless steel. In various parts of the manufacturing and welding process, welding technology was an important role in Chapter. TIG arc welding technology is in general based on the principle of using argon gas welding of stainless steel protection, high current through the welding of stainless steel welded base material being formed on the melt into liquid solution pool, the welded metal and to achieve a combination of welding consumables welding metallurgy, welding, melting at high temperature argon gas continuously sent, so that welding can not contact with oxygen in the air, thus preventing the oxidation of welding consumables, so you can weld a variety of non-ferrous metals.
Divided according to the different welding electrode welding and MIG welding of two non-polar melting.
1. Non-metal arc welding
The principle and features: MIG welding is a non-arc melting in non-polar (usually tungsten) and the workpiece burning around the welding arc and metal flow through a chemical reaction without an inert gas (argon used ), the formation of a protective hood so that the extreme head of tungsten arc and weld pool and hot metal is not already in contact with air, can prevent the oxidation and absorption of harmful gases. Welded joints to form a dense, very good mechanical properties.
2. Melting Inert Gas
Working principles and characteristics: wire sent by wire wheel, tip and conductive, between the base metal and wire arc, the welding wire and base metal melting, and the protection of inert gas argon arc and molten metal to be welded. It TIG difference: one is the wire for the electrodes, and was constantly filled bath melts, condensation to form the weld; the other is the use of protective gas, MIG welding with the application of technology to protect Argon gas has been the development of a single variety of a wide range of mixed gas applications, such as Ar 80% + CO220% of the argon-rich shielding gas. The former is usually referred to as MIG, which is known as MAG. Its mode of operation, the current most widely used semi-automatic MIG welding and argon-rich mixed gas arc welding, followed by automatic MIG welding.
The reason why welding process in manufacturing vibrating screen occupied a pivotal position because: TIG has the following advantages.
Argon in the air can be isolated from oxygen, nitrogen, hydrogen arc and weld pool on the adverse effects, and reduce the burning of alloying elements to be compact, non-flying, high quality of welded joints;
Combustion stability of the arc welding, the heat concentrated high temperature arc welding high production efficiency, narrow heat-affected zone, the cast iron welding wire , deformation, cracks tend to small;
Argon arc welding for the next operation, easy observation;
Electrode loss is small, easy to maintain arc length, welding, flux-free, drug-coated layer, so easy to mechanization and automation;
TIG weld almost all metals, especially some refractory metal, easily oxidized metal, such as magnesium, titanium, molybdenum, zirconium, aluminum and its alloys;
TIG welding because of the characteristics and omnipotent obtained by the completion of the high quality of welding joints, so welding in manufacturing vibrating screen, the production process plays a vital role.
