T welding is a welding technique where the joint is formed in the shape of a T. It is most commonly used for components that require such a shape. The T-weld will have a base and another piece of metal that is attached to it like a T. The two pieces of metal are held together by welding either side of the T.  The joint is formed by first cleaning both the metal surfaces that are to be weld. The metal is placed on top of the base metal in a vertical manner. The right side is first weld at the joint of the two metals. The welder would then proceed to weld the left side of the metal without leaving support to the horizontal metal. This way both the sides of the metal are joined together and the vertical metal is joined to the base metal forming a T shape. This technique, as the shape of the final piece becomes, is known as T- welding.
