Tungsten inert gas (TIG) welding is a high-quality welding process that is used for certain applications that require high precision and high-quality production. A variety of industries use it, but robotic TIG welding is a mainstay in the automotive, aircraft, and heavy industrial industries.
How TIG welding works
In traditional arc welding, an electric arc is created between the power supply electrode and base material. Once activated, the contact points melt the metals together. In robotic TIG welding, a non-consumable tungsten electrode is gas fed between the torch and the metal being welded. Companies that apply welding techniques can use filler material in TIG welding. For example, welding rods can be used which rest in the weld puddle. The filler material is used to build-up or reinforce between the power source and metal.
TIG welding allows for separate heat input control, adding flexibility when working with various metals. Manufacturers appreciate the greater control over heat and amperage that TIG welding offers.
When to use TIG welding
TIG welding is ideal when you need to weld small parts or when extra precision is necessary. Robotic TIG welding can be used for a wide range of applications. Robotic TIG welding can be used for weld modes that use materials that are thin. The application generates limited splatter, with reduced burn-through and warping:
- Cold metal transfer
- Surface tension transfer (STT)
- Regulated Meta Deposition (RMD)
- Active Wire Feed Process (AWP)
What are the benefits?
TIG welding is ideal for the high-quality welding of metals where less margin for error is required. Joining metals using TIG welding provides for quicker arc starting, stability, and an extended electrode life. Therefore, projects requiring detailed designs and curves benefit from TIG welding.
Since you can easily start and stop the welding process, TIG will add accuracy and precision to your projects. TIG welding will also help you to improve on safety measures. Additional controls enable manufacturers to be flexible, working with very low-to-high temperatures, and everything in between. Improving on operations simplicity, TIG welding allows for greater repeatability, with reduced consumables. TIG welding users will also benefit from a reduced number of defects and rework.
