If you are welding anything, you must know the nature of welding objects, the weld, and the position at which objects should fuse.

According to the requirement, there are some different types of welding joints. These types vary according to the goal of welding and the need for the customer.

We must consider the nature of the welding object and the weld's nature before deciding the position at which the weld should apply. 

If we talk about the category of welding joints, experts divide those joint into a few types;

Angle joint

The weld takes place by putting the pieces adjacent in position. The molten welding agent is pouring to achieve more durability welding.

The placement of metal objects side by side is possible when they have edges.

This angle or edge welding is considered the best welding regarding this situation. It is mostly using to make the design in infrastructural works.

Lap joint

In the process of lap joint welding, the metal pieces are placing over each other. And the sides of these are weld together. This Welding joint is like a tack welding joint. The metal objects are overlapping in this position, and a weld is making on the sides. While in tack welding, the metal sheets are allowed to weld by applying temperature and pressing them to make the weld. A lap joint involves when then the size of the two parts is not the same.

Butt joint

Both items are placing inside to sideway, and the weld applies over their corners.

It is most comfortable to fix. It's is the joining of different pieces in parallel manners.

Required objects are placing adjacent to each other, and the weld is applying over the sides.

It is the same as joining the bricks to make a pathway.

T shaped joint

This joint is applied two metal pieces when placed straight to the ground and the other on standing position over it. The proceeding of this type of joint is the same as the English alphabet "T"; that's why it is called a T-shaped welding joint. In infrastructural activities, these joints use by placing an object at the angle of 180°, and other itemsets over the first one to make "T" at a 90° angle. The uses of this joint to design something.


This article defines the different types of welding joints to meet the requirements of costumers. The joints' positions are necessary to attain the desired results to construction activities and make automobile structure. Some types of joints in welding also helps to maintain the quality standards of welding in some cases.
