Types of weld joint
How many types of weld joints are there?
five different types
There are five different types of welding joints that can be carried out: butt, lap, corner, edge and tee.
What are the 3 types of fillet joint?
Fillet welded joints such as tee, lap and corner joints are the most common connection in welded fabrication. In total they probably account for around 70 to 80% of all joints made by arc welding.
What are the 3 types of welding?
However, there are many different types of welding processes used today, for different effects and needs. Three of the most common are Arc, MIG (Metal, Inert Gas) or GMAW (Gas, Metal Arc Welding), and TIG (Tungsten Inert Gas) welding.
What are the 5 welding joints in structural welding?
The five basic weld joints include the butt joint, the lap joint, the tee joint, the corner joint, and the edge joint. The butt joint occurs when two members are placed side-by-side or butted together. The weld is made along the seam that adjoins the two adjacent pieces.
What are the 7 basic types of welding?

What is weld size?
For fillet weld, the weld size is the distance from the root to its toe and weld throat is the minimum distance from the root of the weld to the face of the weld. For groove weld, the weld size is the width of the weld coverage and weld throat is the depth of the groove filled with weld.
Which weld joint is strongest?
TIG welding is often considered the strongest weld since it produces extreme heat, and the slow cooling rate results in high tensile strength and ductility. MIG is also an excellent candidate for the strongest type of weld because it can create a strong joint.
What is the common type of joint in welding?
Butt Joint Welding
A square grove weld is another name for a butt joint weld. It’s the simplest and, by far, the most common type of weld. It is made up of two flat pieces that are parallel to each other.
What is the difference between a weld and a joint?
Rivet joints are also semi-permanent, in that they can be cut and removed, whereas welded joints are considered to be a permanent form of joining. Additionally, a welded joint produces a smooth finish, while a riveted joint will protrude from a structure’s surface.
What are the types of fillet weld?
There are two main types of fillet weld: transverse fillet weld and parallel fillet weld.
Why is it called a fillet weld?
The most popular weld is the fillet weld, named after its cross-sectional shape.
What is fillet weld size?
Fillet weld sizes are measured by the length of the legs of the largest right triangle that may be inscribed within the fillet weld cross section. Fillet weld sizes determine theoretical throat.
What is fillet weld explain?
noun. : a weld of approximately triangular cross section used to join two pieces especially perpendicularly.
What is the minimum weld thickness?
Except that the weld size need not exceed the thickness of the thinner part joined. Minimum size for cyclically loaded structure shall be 3/16in [5mm].
What is the strongest weld joint?
TIG welding is often considered the strongest weld since it produces extreme heat, and the slow cooling rate results in high tensile strength and ductility. MIG is also an excellent candidate for the strongest type of weld because it can create a strong joint.
Where is edge joint used?
Edge joints are usually used when two pieces of sheet metal have flanging edges. Other applications tend to be in places where a weld is the only way to attach pieces that are next to each other. Typically, the metal parts will be side-by-side and then welded on the same edge.
How do you calculate weld size?
Calculate the weld size, s, at each node on the intersecting edge of the terminated part:
- SS or DS groove welds: s = t. w
- SS or DS 45 ° fillet welds: s = sqrt(2) × t. w
