Tungsten Inert Gas (TIG) is an arc welding technique. It joins metals using a non-consumable tungsten electrode. The process involves joining a workpiece and a pointed tungsten electrode with an arc in an inert argon or helium environment. These pointed electrodes produce tiny, powerful arcs perfect for accurate, high-quality welding.
Welders do not have to balance the heat input from the arc because the electrode is not consumed. They add filler metal to the weld pool separately if needed.
Below, we explore the pros and cons of the tig micro-welding technique. This will help you make an informed choice for your project.
Benefits
Clean superior welds
TIG’s improved arc and weld puddle control results in clean welds. This is important when the project requires aesthetics. It gives the welder exact control over the surface bead. This is by allowing them to regulate the temperature of the weld puddle using a foot pedal. This is much like when operating a car. TIG welding is, therefore, perfect for aesthetic welds like metal sculpture and automobiles.
Moreover, TIG welding produces no smoke or odors unless the metal being welded contains oil, grease, paint, lead, or zinc. Clean base metal is the ideal starting point for welding. There is no spatter or sparks while working with clean metal. This is because the welding puddle only includes the required quantity of filler metal.
No flux usage
Since the argon gas shields the weld puddle from contaminants, neither flux nor usage is required. Additionally, the final weld won’t have any slag that must be cleaned off between passes.
By avoiding flux, the welder can boost their overall productivity. They do not have to spend additional time cleaning the weld to make it seem acceptable.
Adaptability
TIG can weld numerous metals, including copper, aluminum, stainless steel, and rare metals like titanium and magnesium. Furthermore, any position—flat, horizontal, vertical, or overhead—can be used for TIG welding. Because of its adaptability, it’s an excellent choice for shops that manufacture roll cages. It is also ideal for welding in constrained spaces.
Better control
TIG welding offers fine-grained control over filler metal deposition, welding speed, and heat input. This degree of control is beneficial when welding complex joints and thin materials. If the welder has more power, the weld will go more smoothly.
It uses only one shielding gas.
Argon is adaptable. Welders only need one gas to TIG weld all metals and thicknesses, making welding easier because they don’t have to deal with different kinds of gas.
Drawbacks
TIG Welding may be challenging
Even though TIG welding supplies and equipment are reasonably priced, it may be challenging. Unexperienced welders find it difficult to manage heat with the pedal. Inadequate inclusions, contaminations, and uneven heating can lead to material waste and distorted or flawed products.
The technique requires knowledgeable and experienced professionals. This is where a TIG welding company comes in.
TIG is more time-consuming
TIG welding is time-consuming. Compared to other technologies, such as stick welding, it takes a lot of time to achieve the level of precision for which it is renowned. There is no margin for mistake because contamination will damage the welded surface. Thus, the equipment itself must also be carefully cleaned after every usage.
Not consistently the most effective for thick materials
TIG welding can handle thick materials. However, it may not be the most effective technique for heavy-duty applications. As a result, it may take the welder longer, mainly if most of the work involves thick materials.
High-priced equipment
The cost of TIG welding equipment, such as the gas supply, torch, and power source, can be higher than that of other welding equipment. However, you don’t have to invest in the welding set-up. Industrial welding companies like Micro Weld provide these services, saving you a lot of resources.
Summing up
TIG welding produces excellent welds with little distortion or spatter. It also works well for welding unusual materials that require precise tolerances and high purity.
