TIG Welding Techniques
About Instructor
Matching your needs and welding skills with a process is critical before moving on to discuss specific welder model options.
OVERVIEW
The TIG welding method creates attractive welds that do not require any finishing process.
It’s most suitable for welding thinner metal, where precise welds are required, such as aluminium truss tubes.
Tungsten Inert Gas (TIG) welding is commonly used for thinner gauge materials. One benefit of the TIG method is that it is less intense, meaning it helps to protect the metal from being melted clean through.The TIG method makes use of a non-consumable tungsten electrode to run a current through the metals being joined. A filler metal may, or may not, be used and argon gas, or other inert gases like helium, would be required during the welding process to protect the weld from contamination. In cases when a filler material is not used, the pieces of metal being welded must get hot enough to form a bond with each other.
Compared to MIG welding, TIG is a slower process and demands a higher degree of welding skill. If a filler is used, increased hand coordination is required, as one hand must hold the torch at the correct angle, while the other hand feeds the wire to create a uniform puddle used to fuse the metals together.
