What is a tee fillet weld?

Tee welding joints are formed when two pieces intersect at a 90° angle. This results in the edges coming together in the center of a plate or component in a ‘T’ shape. Tee joints are considered to be a type of fillet weld, and they can also be formed when a tube or pipe is welded onto a base plate.

What is the difference between a fillet weld and a groove weld?

If the weld is between the two workpieces, it is a groove weld. If the weld is beside the two workpieces, it is a fillet weld. The weld will be placed in between the two workpieces. When the weld extends completely through the thickness of the joint, it is called complete joint penetration (CJP).

What are the three fillet welds?

Some of the simplest and most commonly used fillet weld joints are the T joint, corner joint, and lap joint.

Is a lap weld a fillet weld?

A lap weld consists of two or more materials that are overlapped on top of one another. A lap weld is categorized in the fillet weld family. Lap welds are commonly used in welding processes that involve automation. The lap joint, which is used when making a lap weld, is very forgiving to varying part dimensions.

Where is fillet weld used?

The weld is triangular in shape and may have a concave, flat or convex surface depending on the welder’s technique. Welders use fillet welds when connecting flanges to pipes and welding cross sections of infrastructure, and when bolts are not strong enough and will wear off easily.

How thick should a fillet weld be?

The minimum fillet weld should be 6 mm.

Can a fillet weld be CJP?

A fillet weld substitution can often be made for CJP groove welds in tension, such as for bolted moment connections where flange plates are welded to the column (W-shape or HSS col- umns).

What are fillet welds used for?

What is the purpose of a fillet weld?

What are the two types of fillet weld?

There are two main types of fillet weld: transverse fillet weld and parallel fillet weld.

What should I know about fillet welded joints?

Fillet welded joints – a review of the practicalities 1 Fillet weld features. BS EN ISO 2553 uses the following notation as Figs. 2 Lap joints welded with fillet welds. As discussed earlier, oversized welds are commonplace and the lap joint is no exception. 3 Summary.

Can a deep penetration fillet weld be made?

A greater strength can be achieved for the same leg length if a deep penetration fillet weld is made; the throat thickness here is measured from the face to the tangent to the root of the weld as in Fig. 6.2. This can be done with submerged arc welding or MAG/MIG welding using higher currents than for the conventional fillet weld.

What is the throat thickness taken as for a fillet weld?

The leg length is usually designated as the size of the weld. The throat of the weld is the distance from the center of the face to the root of the weld. Typically the depth of the throat should be at least as thick as the thickness of metal you are welding.

What are the face profiles of fillet welds?

By convention there are three definitions of face profiles of fillet welds as shown in Fig. 6.2; the mitre fillet which has a flat face, the convex fillet and the concave fillet.
