Buying Guide for TIG Welding Equipment
To establish a coalescence between two or more metals, an arc is formed between a non-consumable tungsten electrode and the work (base metal) in TIG welding. Non-consumable electrodes are available in a variety of diameters and lengths and are usually constructed of pure tungsten or a tungsten alloy with additional elements and oxides, as tungsten has the highest melting point of any metal at 3,410 degrees Celsius.
benefits of tig welding equipment
Enhanced control
The tungsten electrode used to create the electrical arc is one aspect of TIG welding that helps to improve control. Because of tungsten's exceptional hardness and high melting point (3400°C), rather than employing a consumable electrode that melts into the weld, as with a stick or MIG welding, the tungsten electrode heats and melts the filler material that the operator feeds into the weld region.
Versatility
TIG welding is a very adaptable welding process for a variety of reasons. TIG welding uses a tungsten electrode and shielding gas (argon) that can be utilized in almost any welding application, so there's no need to switch it out depending on the job.
No need to clean after welding
When compared to other procedures, TIG welding offers six of one and half a dozen of the other. Few welding procedures do not include a cleaning step, therefore cleaning is more of a point where TIG welding varies from other methods than an advantage. Because TIG welding is so exact and regulated, things like spatter and sparks aren't an issue, therefore TIG welds are almost ready to use after the welding is finished.
Ready to use
TIG welding is so exact and regulated, problems like spatter and sparks aren't an issue, therefore TIG welds are almost ready to use immediately the welding is finished. Other welding procedures require post-weld cleaning steps, which are considerably reduced or eliminated in this process.
Factors considers before buying tig welding equipment
Cost
It's worth noting that filler rod prices will rise in tandem with base metal prices. A less expensive rod ($2-3/lb.) is appropriate for most carbon steels, but a filler compatible with alloyed stainless steel might cost $20 per pound or more.
Warranty
When buying a TIG welder, make sure you get the correct coverage so you're covered if anything goes wrong. A warranty ensures that you receive the necessary aftercare to resolve issues and keep your computer in good working order.
Material
Many factors influence which material is best for a given application, including the type of weld, the composition of the material being welded, and the amperage level, among others. Testing is the most effective technique to discover which tungsten material is suitable for a certain application.
Size and distribution
The distribution of oxygen is an important measure of quality. Oxides should be evenly dispersed throughout the tungsten. Uneven distribution leads to poor performance: places with little or no oxides suffer from grain development, whereas areas with too much oxide "bottleneck," preventing the oxides from reaching the point. Higher-quality oxides have a smaller size, making it easier for them to move to the tip.
Conclusion
This specification is intended to aid welders in selecting and preparing the tungsten electrode, which is one of the most essential and sometimes overlooked welding process variables. Welders can spend thousands of dollars on equipment, but if they don't choose and prepare their electrodes appropriately with this less expensive process component, their welding outcomes can be poor, inconsistent, or troublesome.
