What is a Fillet Weld in Welding?

A fillet weld is a type of welding joint in which two pieces of metal are joined together at approximately right angles. Fillet welds are commonly used to join plates and beams in Lap joints, T-joints, or corner joints.

What is fillet weld size?

The size of the weld is typically determined by the thickness of the metal being joined, and fillet welds are typically used when the thickness of the metal is 3/16 inches (4.8 mm) or less.

Fillet welds are strong and have good resistance to shear and tension stresses. However, they are not as strong as butt welds and are not typically used for load-bearing applications.

What is fillet weld and groove weld?

A fillet weld is a type of welding joint in which two pieces of metal are joined together at approximately right angles, while a groove weld is a type of welding joint in which two pieces of metal are joined together in a groove.

What are the 3 types of fillet joints?

There are three types of fillet welds:

Lap joint: A lap joint is created when two pieces of metal are joined together at the end of one piece.
T-joint: A T-joint is created when two pieces of metal are joined together in the middle of one piece.
Corner joint: A corner joint is created when two pieces of metal are joined together at the corner of one piece.

Transverse fillet weld

A transverse fillet weld is a type of welding joint in which two pieces of metal are joined together along the length of one piece.

Fillet weld advantages and disadvantages

Advantages:

Fillet welds are strong and have good resistance to shear and tension stresses.
Fillet welds can be made using various welding processes, including oxy-fuel welding, gas tungsten arc welding, and plasma arc welding.
Fillet welds are less likely to cause warping or distortion than butt welds.

Disadvantages:

Fillet welds are not as strong as butt welds, and are not typically used for load-bearing applications.
The size of the weld is typically determined by the thickness of the metal being joined, and fillet welds are typically used when the thickness of the metal is 3/16 inches (4.8 mm) or less.

What is intermittent welds?

Intermittent welds are welds that are not continuous. That is, they are not made in one uninterrupted pass. Instead, they are made in short segments with gaps between them. Intermittent welds are commonly used in lap joints and T-joints.
