Dakota Ultrasonics Transducer Wedges

Q: How do I choose between 45°, 60°, and 70° refracted wedge angles?

70° Wedge: Best for thin plates ( 0.25" to 0.75" ) and shallow skip paths to reach root passes with a steep beam angle. 60° Wedge: The industry standard for medium-to-thick structural welds ( 0.50" to 1.50" ) and 30° V-groove bevels. 45° Wedge: Used for heavy plate and thick-wall piping ( over 1.50" ) and detecting root cracks or T-joint defects.

F.A.Q.

How do I choose between 45°, 60°, and 70° refracted wedge angles?

70° Wedge: Best for thin plates (0.25" to 0.75") and shallow skip paths to reach root passes with a steep beam angle.

60° Wedge: The industry standard for medium-to-thick structural welds (0.50" to 1.50") and 30° V-groove bevels.

45° Wedge: Used for heavy plate and thick-wall piping (over 1.50") and detecting root cracks or T-joint defects.

Can I use a Quick Change Transducer with a Standard SW Wedge?

No. Quick Change Transducers feature a threaded cylindrical nose that only threads into QW Quick Change Wedges. Standard Transducers use a rectangular screw-mount base designed exclusively for SW Standard Wedges and SNW Snail Wedges.

Do I need couplant between the transducer and the wedge?

Yes. Always place a small drop of ultrasonic couplant or light oil between the transducer face and the wedge mounting surface before tightening or threading them together to eliminate trapped air gaps.
