What is Coating Concentricity in Welding?

Welding is the process of joining two or more pieces of metal together by heating them to a point where they melt and flow together. In order to ensure a strong weld, it is important that the metals being joined are of similar thickness. Otherwise, the weld will be weaker and more likely to break.

Coating concentricity is a measure of how evenly the coating is applied to the core wire or rod. Achieving good coating concentricity is important in welding because it ensures that the molten metal will flow evenly around the electrode, resulting in a stronger weld. Poor coating concentricity can cause the molten metal to flow unevenly, resulting in a weaker weld.

There are several factors that can affect coating concentricity, including the type of coating, the speed at which the coating is applied, and the temperature of the metal. Ensuring good coating concentricity is crucial to achieving a strong weld.

Concentricity gd&t example

Concentricity is a 3D geometric tolerance that controls the placement of a feature relative to another feature. It is typically used to control how closely two cylindrical features are to one another. The illustration below shows an example of two features with concentricity applied. In this example, the two holes must be within 0.010″ of each other.

Coaxiality vs concentricity

Coaxiality and concentricity are often confused because they both involve cylindrical features. However, there is a key difference between the two tolerances. Coaxiality controls the alignment of two cylindrical features, while concentricity controls the placement of a feature relative to another feature.

Concentricity symbol meaning

The concentricity symbol is a small circle with a line through it. It is typically used in GD&T to indicate that a feature must be placed within a certain tolerance of another feature.
