The 5 weld joints are called Butt joint, Corner joint, Edge joint, Lap joint and Tee joint. The first one called Butt joint is a joint that is between two members lying around in the same plane. The second one named Corner joint has two members placed at right angles to each other in a form of an angle, generally 90 degrees. The third one named Edge joint is a joint between the ends of two or more parallel members. Fourth one is a Lap joint, which has two overlapping members to form the joint. Fifth one is the Tee joint; it looks just like it is called because it forms a “T”.

The TIG has the following advantages and disadvantages

Advantages
• All metals, all positions
• Easy to mechanize and automate
• High quality welds, low distortion
• Flexibility and ease of heat control

And Disadvantages
• Arc blow sensitive
• Lower deposition rates
• Sensitive to cleanliness and contamination
• Good skills required
