Visualize ultrasonic shear-wave beam paths against real weld joint geometry. Adjust parameters and see results update in real time. Complete insight, no guesswork.
The horizontal distance from the probe index point to the point where the shear-wave beam first intersects the back wall. Calculated as t x tan(θ) where t is wall thickness and θ is the refracted shear-wave angle.
The actual path length the ultrasound travels through the material for one full leg (surface to backwall). Calculated as t / cos(θ).
After hitting the back wall, the beam reflects and travels back toward the surface (Leg 2), then reflects again for Leg 3, and so on. For T-Joint and Corner joints, the beam also reflects off the vertical plate outer face, reversing the horizontal direction.
Each joint configuration uses 12 coefficient-based points that scale with cap width, root/web width, and material thickness. This produces accurate V-groove, U-groove, J-groove, T-joint, and corner profiles matching real-world joint preparations.
