⒈ Like TIG welding, it can weld almost all metals, especially suitable for welding aluminum and aluminum alloys, copper and copper alloys, stainless steel and other materials. There is almost no oxidation burning loss during the welding process, only a small amount of evaporation loss, and the metallurgical process is relatively simple.
⒉ high labor productivity
⒊MIG welding can be DC reversed, welding aluminum, magnesium and other metals has a good cathode atomization effect, which can effectively remove the oxide film and improve the welding quality of the joint.
⒋Do not use tungsten electrode, the cost is lower than TIG welding; it is possible to replace TIG welding.
⒌When MIG welding aluminum and aluminum alloys, the sub-jet droplet transfer method can be used to improve the quality of the welded joints.
⒍Since argon is an inert gas and does not chemically react with any substances, it is more sensitive to oil stains and rust on the surface of the welding wire and base metal, and it is easy to generate pores. The welding wire and workpiece must be carefully cleaned before welding.
⒊MIG welding droplet transfer
Droplet transfer refers to the whole process in which the molten metal at the end of the welding wire or electrode forms a droplet under the action of arc heat, and is detached from the end of the welding wire and transferred to the welding pool under the action of various forces. It is directly related to the stability of the welding process, weld formation, spatter size, etc.
⒊1. The force affecting the transfer of molten droplets The droplet formed by the molten metal at the end of the welding wire is affected by various forces, and the influence of various forces on the transfer of the droplet is different. ⒈ Gravity: in the flat welding position, the direction of gravity is the same as the direction of the droplet transfer, which promotes the transition; the overhead welding position hinders the transfer of the droplet
⒉Surface tension: the main force to maintain the droplet on the wire end, the thinner the wire, the easier the droplet transition.
⒊Electromagnetic force: The force generated by the magnetic field of the conductor itself is called electromagnetic force, and its axial component force always expands from a small section to a large section. In molten electrode arc welding, the cross-section of the conductor changes when the current passes through the wire-droplet-electrode spot, and the direction of the electromagnetic force also changes. At the same time, the high current density at the spot will cause the metal to evaporate strongly, and will also have a great reaction force on the surface of the molten metal. The effect of electromagnetic force on droplet transfer depends on the arc shape.
⒋Plasma flow force: Under the contraction of electromagnetic force, the hydrostatic pressure generated by the arc plasma in the direction of the arc axis is inversely proportional to the cross-sectional area of the arc column, that is, it gradually decreases from the end of the welding wire to the surface of the molten pool. Favorable factors to promote droplet transfer.
⒌ Spot pressure
⒊2. Droplet transfer characteristics of MIG welding In MIG welding and MAG welding, short-circuit transfer and jet transfer are mainly used for droplet transfer. Short-circuit welding is used for high-speed welding and all-position welding of thin plates, and jet transfer is used for horizontal butt and fillet welding of medium and thick plates.
In MIG welding, DC reverse connection is basically used. Because the fine jet transition can be achieved in the reverse connection, and the positive ions hit the droplet in the positive connection, which produces a large spot pressure to hinder the droplet transition, so that the normal connection is basically an irregular droplet transition. Alternating current is not suitable for MIG welding because the melting of the wire is not equal on each half-circle.
When using MIG welding to weld aluminum and aluminum alloys, because aluminum is easy to oxidize, in order to ensure the protection effect, the arc length cannot be too long during welding, so we cannot use the jet transition method with large current and long arc length. If the selected current is greater than the critical current, and the arc length is controlled between the jet transition and the short-circuit transition, a sub-jet transition is formed.
MIG welding is now widely used for welding aluminum and aluminum alloy workpieces.
