Welding of metal by semiautomatic device Mig

Are you interested in welding metals using the MIG semiautomatic from the supplier AvecGlob? Here you will find interesting information on this topic /

The essence of the method

MIG is an abbreviation for the semiautomatic welding of a metal electrode in an inert gas stream. MIG is also called gas arc welding.

The arc is ignited by touching the electrode located in the drive electrode holder — the welding tractor. It is shielded with an inert gas, and the supply wire serves as a source of supply of the molten metal to the welding zone. Since the consumable material — wire — is fed from the coil with MIG, this method is semi-automatic welding. semi-automatic welding process. It is characterized by increased uniformity of the parameters of the weld, which does not depend on the qualification of the welder.

At MIG welding is carried out under a layer of welding slag, the composition of which is determined by the chemical composition of the welded materials. A protective gas is used, usually argon, argon with the addition of 1 to 5% oxygen, argon with the addition of 3 to 25% carbon dioxide, and a combination of argon and helium. The semi-automatic nature of the process allows welding parts located in any position, and at any length of the welded seam without stopping. After welding, the weld zone must be stripped.

Sequence of the semi-automatic MIG welding process

The welding arc is excited between the wire electrode and the workpiece. During the MIG welding process, the electrode melts inside the arc and precipitates as a filler. The protective gas used prevents atmospheric pollution from contamination and protects the weld during curing.

Protective gas also contributes to the stabilization of the arc, which ensures a smooth transfer of metal from the welding wire into the molten weld pool.

Supplier — AvekGlob Company — offers at affordable prices from the manufacturer various metals and alloys, in the quantity and assortment that are required by the customer. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Advantages of semi-automatic electrode welding (MIG)

Universality is the main advantage of this technology. With this type of welding, there are no special requirements for welded metals and alloys, there are no restrictions on the configuration and degree of complexity of the weld, although it is preferable to place the products in a horizontal position.

With semi-automatic MIG welding, it is possible to obtain T-shaped, angular, end and butt welds.

The MIG method is used for welding many materials, and various gases are used to form the arc, depending on the materials to be welded. Thus, a mixture of argon and CO _{2 is} usually used for welding of mild steel, aluminum, titanium and alloys. Helium is used for welding mild steel and titanium in a high-speed process, and this gas is also used for welding copper and stainless steel. Carbon dioxide is most commonly used for welding carbonaceous and low-alloy steels.

Supplier — AvekGlob Company — offers to purchase various metals, alloys, welded structures in any quantity and range of sizes. Products can be bought at a price formed on the basis of European and world standards of production. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
