Final answer:
The five basic joints used in welding are square, U, J, bevel, and flare-bevel joints.
Step-by-step explanation:
The five basic joints used in welding are:
- Square joint: This joint is formed when two metal pieces are welded together at a right angle.
- U joint: This joint is formed when two metal pieces are welded together in the shape of the letter U.
- J joint: This joint is formed when two metal pieces are welded together in the shape of the letter J.
- Bevel joint: This joint is formed when the edges of two metal pieces are angled to create a V shape.
- Flare-bevel joint: This joint is formed when the edges of two metal pieces are angled to create a V shape, with one side flared out.
These are the fundamental types of joints used to join metal in a variety of configurations, each suited to different structural needs and material types. For instance, a butt joint is used to join two pieces of metal end to end, typically in the same plane. A tee joint is used when two pieces intersect at a right angle. Corner and edge joints are similar, often used in sheet metal fabrications. Lastly, a lap joint involves two pieces of metal that overlap with one another.
