What is the angle of beam?
The beam angle is a beam of concentrated directional sound waves used to test welds and metal industrial components for disorders or small cracks perpendicular to the surface of the tested piece. Small cracks in welds or metal may be invisible to the mere eye, but the beam angle can be detected by such disorders. Angle beams are important tools for testing many important industrial components, including machines, pipes, welds of all types and machined or forged metal components. The wedge is designed to hold the converter at an angle due to the surface of the tested piece. The converter is a powered device that generates and projects sound waves into a piece. Most of the beam assemblies are designed to allow the connection of different wedges to the converter. Each other wedge focuses a beam at different angles for different testing conditions.
The beam angle sets on Snell's law. This law allows you to calculate the angle at which the sound wave bounces when fromAsks the boundary between two materials of different density. The beam angle fires a beam into a tested piece and detects all back rays that indicate cracks or disorders perpendicular to the surface of the test piece.
converters are specialized; It must be set to a specific frequency depending on the material testing. The most common types are for steel testing. Other converters are produced for testing materials such as aluminum and titanium. The converter designed for testing one type of material is not suitable for testing different material, because each is calibrated for a specific sound conductivity of only one substance.
wedges for the beam of the beam converter are sometimes manusnaciously with a curve to provide more accurate values in testing materials with curved surfaces. May be either convex or concave, with axis of the curve running either perpendicular or parallel to the beam line convertku. Different patterns allow testing of internal or external curves of pipes or other devices.
There are also assemblies of an angle beam converter for testing other materials such as plastics, high -density and metal ceramics such as copper and lead. Double beam converters are sometimes used to test higher accuracy tests in testing certain materials such as stainless steel. High -temperature rays are available for specialized testing under high temperature conditions.
