TIG argon arc welding machines are a common welding process, also known as tungsten inert gas protection welding. Its working principle is to use a non-consumable tungsten electrode to generate an electric arc between the electrode and the workpiece to melt the metal. At the same time, an inert gas (usually argon) is introduced to isolate the air and protect the molten pool, preventing oxidation.
When the following situations occur, argon arc welding can be given priority:
1. Materials: Aluminum, magnesium, stainless steel, titanium, copper and other non-ferrous metals or special alloys.
2. Thickness： Thin plates， such as those as thin as 0.5mm. Precision parts， such as instruments， jewelry， medical devices， electronic components， etc.
3. Quality requirements： Extremely high requirements for the internal quality, appearance, and corrosion resistance of the weld.
4. Process requirements: Pipeline base welding (in the pipeline welding of the petrochemical and power industries, the first layer of base welding must be done with argon arc welding to ensure a good formation on the back of the root weld without oxidation)， single-sided double-sided formation (required in high-quality occasions where the back of the weld can also be formed uniformly and beautifully)， all-position welding (including flat， horizontal， vertical， and overhead positions， especially in confined spaces such as pipeline installation).
From the perspective of types, argon arc welding can be divided into direct current argon arc welding, AC/DC argon arc welding, and AC/DC pulsed argon arc welding. The most core difference among these three is the difference in the materials they are suitable for. Direct current argon arc welding is suitable for carbon steel, stainless steel, titanium alloys, copper alloys and other black metals and non-aluminum-magnesium type non-ferrous metals; AC/DC argon arc welding is suitable for all materials of the AC type, with additional aluminum-magnesium alloys; AC/DC pulsed argon arc welding covers all materials of the AC/DC type, and is particularly good at thin plates, heat-sensitive materials.
If you only weld carbon steel and stainless steel, and mainly use medium-thick plates, then choose direct current argon arc welding, which has a high cost-performance ratio; if you also need to take into account aluminum-magnesium alloys or black metals, choose AC/DC argon arc welding, which is multi-functional with one machine; for those with high requirements for deformation, welding thin plates, precision parts or full-position welding, choose AC/DC pulsed argon arc welding, which has precise heat control and the best welding quality.
