WebThe angle of reflection \theta_r of a ray or beam is the angle measured from the reflected ray to the surface normal. From the law of reflection, \theta_i=\theta_r, where \theta_i is the angle of incidence. \theta_r is measured between the ray and a line normal to the surface that intersects the surface at the same point as the ray. See also: Angle of Incidence, … WebBeam angles of 0°, 45°, 60° and 70° are recommended as standard. Whether shear or compression wave angled probes are optimum will depend on the weld design, as will the other probe variables (size, frequency etc.). Wherever possible, ‘creeping’ wave probes to augment the angle beam probes should be used to cover the following possibilities:
