What is Reinforcement in Welding?
Reinforcement in welding is defined as the welding metal, at the face or root, in excess of the metal necessary to fill the joint.
What is the purpose of reinforcement in welding?
The purpose of reinforcement is to compensate for any lack of fusion between the weld and base metals. It also helps to resist cracking and provides additional support to the joint. Reinforcement can be achieved by using a filler metal with a higher melting point than the base metal, by adding additional weld passes, or by increasing the welding current.
Reinforcement is often specified on drawings or in welding procedures to ensure that the proper amount of metal is deposited in the joint.
In most cases, reinforcement is not visible on the surface of the weld. However, if the weld metal is not properly fused to the base metal, the reinforcement will be visible as a raised bead on the surface of the weld. Reinforcement can also be seen on the root side of a weld, where it appears as a bright, shiny band.
What is the height of reinforcement in welding?
The height of reinforcement in welding is the distance that the weld metal extends above the level of the base metal. This distance is typically specified on drawings or in welding procedures. The amount of reinforcement required will depend on the application and the type of weld being made. In most cases, the height of reinforcement should be between 1/16 and 1/8 inch.
How is welding reinforcement measured?
Welding reinforcement is measured by the amount of weld metal deposited in the joint. This can be done by weighing the weld metal before and after welding, or by measuring the thickness of the weld with a micrometer.
Is welding of reinforcement allowed?
Yes, welding of reinforcement is allowed as long as the proper amount of metal is deposited in the joint. Too much reinforcement can result in a joint that is difficult to inspect, while too little reinforcement can cause cracking or failure of the joint.
