Types of Fillet Weld
A fillet weld is a type of weld joint that is created by filling the gap between two pieces of metal with weld material.
There are several types of fillet welds, including:
Partial penetration fillet welds: Partial penetration fillet welds are welds that do not extend all the way through the thickness of the metal being joined. They are typically used when the metal being welded is thin or when only a small amount of strength is required at the joint.
Full penetration fillet welds: Full penetration fillet welds extend all the way through the thickness of the metal being joined. They are typically used when the metal being welded is thick or when a high degree of strength is required at the joint.
Single bevel fillet welds: Single bevel fillet welds are welds that are created by beveling one edge of the metal being joined. They are typically used when the metal being welded is thin or when only a small amount of strength is required at the joint.
Double bevel fillet welds: Double bevel fillet welds are welds that are created by beveling both edges of the metal being joined. They are typically used when the metal being welded is thick or when a high degree of strength is required at the joint.
Convex fillet welds: Convex fillet welds are welds that have a curved, outward-facing surface. They are typically used when the metal being welded is thin or when only a small amount of strength is required at the joint.
Concave fillet welds: Concave fillet welds are welds that have a curved, inward-facing surface. They are typically used when the metal being welded is thick or when a high degree of strength is required at the joint.
Fillet welds are named after their triangular shape, which is similar to a right triangle with the hypotenuse on the top and the other two sides forming the legs of the triangle.
Fillet welds can be used to join two pieces of metal at a right angle, as well as to join two pieces of metal that are angled or skewed relative to each other.
