What is TIG welding machine?

Welding machine refers to the use of electrical energy, thermal energy and mechanical energy to heat or pressurize, so that the welding material can achieve the combination between atoms, so that the mechanical equipment is permanently connected. TIG welding machine is one of them.

The full name of TIG is Tungsten Inert Gas, and it is also known as GTAW, that is, Gas Tungsten Arc Welding. It is a high-precision arc welding equipment that uses non-consumable tungsten electrodes as electrodes and uses argon, helium and other inert gases to protect the welding area. TIG welding machine has several core features. The first is the material of TIG welding machine. The use of tungsten electrode with high melting point can keep the electrode from melting during the welding process. Adding rare earth oxides such as cerium oxide can increase the stability of the arc and prolong the life of the electrode. The second is the three welding modes of TIG welding machine. DCEN DC connection capacity is deep, suitable for stainless steel, steel and other materials. DCEP DC reverse connection is suitable for aluminum-magnesium alloy materials, which can clean up the oxide layer. AC AC cleans up the oxide layer when welding aluminum or magnesium, and at the same time, it can also take into account the melting depth. The third is the commonly used protective gas: argon-helium mixture or argon can prevent the melting pool from reacting with the air and being oxidized. The last important feature is that the TIG welding machine generally does not use the welding wire as the welding material, but it can automatically add the welding wire as needed. These features can enable TIG welding machine to carry out high-precision welding.

TIG welding machine has its advantages and disadvantages. The advantages are that the welding quality is high, the welding is pure, and there is no splashing. It is suitable for food-grade or scenes with high requirements for appearance, such as medical equipment and artistic creation. The disadvantage is that the cost is higher than that of MIG welding machines. At the same time, due to the need to coordinate welding wires, welding guns and pedals, the ability requirements for operators are also much higher.

In a word, TIG welding machine has obvious advantages for easy-to-oxidize metals, thin plate welding and other scenarios. It is a common equipment for precision welding and special metal welding, especially in the field where the quality requirements of welds is strict.Genuinsky is a professional manufacturer and supplier of TIG welding machines in China.
