Argon arc welding apparatus

Before answering the question about the apparatus of argon arc welding, let's remember what argon welding is in general. In practice, several types of formation of non-separable joints from metal are used, the most popular of them is electric arc welding in the open air. Meanwhile, there is also a type of fighting performed in protective gases, for which it is necessary buy an argon welding machine. One of these gases is argon.

Argon is an inert gas, that is, it does not react with other substances. It is this property that allows ego to be used to create a gas cloud around the welding bath. The use of a protective layer of this gas provides reliable isolation from the effects of atmospheric oxygen on the expanded metal. Such insulation ensures the quality of an integral connection (welded seam). For the production of argon welding, it will be necessary to use a device specially made for it. The main thing is to correctly ensure the operating modes of the welding machine. In essence, argon welding is a type of electric arc welding produced by a fusible or non-fusible electrode in an argon cloud. A refractory metal, tungsten, is used for the manufacture of a non-melting electrode.

Equipment for this type of quarrel

To perform argon welding, the following set of equipment will be required:

• Welding current source.

• Welding wires.

• Cylinder with gas and reducer.

• Hose for supplying gas.

• A welding gun equipped with a tungsten electrode and a gas supply device.

Depending on the tasks to be solved, the equipment can be equipped with a welding wire feeder.

Welding is performed as follows: the current source provides the energy necessary for welding. Energy is supplied to the electrode. The welder brings the welding gun to the place where the workpieces are joined and ignites an arc between the electrode and the workpiece. At the same time, it starts the mechanism for feeding the wire and supplying the gas that creates the protective cloud.

Scope

This method allows you to use welding to join ferrous and non-ferrous metals, including stainless metals. In particular, equipment for the food and pharmaceutical industry is produced with the help of welding of this type. Argon welding is used in the manufacture of various containers. Both the aircraft industry and the space industry cannot do without argon strife. The devices are widely used in the manufacture of equipment for nuclear power plants.

It can be said that argon welding devices are used in areas where it is necessary to obtain high-quality welds on parts made of non-ferrous metals, stainless steel and ordinary ferrous metals.

This type of welding ensures the quality of the welded joint, prevents the appearance of drops of molten metal settling in the immediate vicinity of the welding site. The appearance of such drops leads to the fact that an operation to remove them is added to the technical process. And this, accordingly, leads to an increase in the cost of the finished product.

The parameters of argon brazing determined its use in different branches of industry.
