Echo Spot Weld™ is a specialized ultrasonic couplant developed for accurate inspection of spot welds. Its acoustic impedance, viscosity, and removal properties are optimized for high-frequency inspections, making it the preferred couplant for 10–15 MHz array go/no-go testing.
The gel formulation stays in place on overhead and vertical surfaces, ensuring consistent coupling during inspections. Echo Spot Weld™ offers a broad operating range, slow drying, and a water-soluble formula, allowing for easy cleanup and safe removal after testing.
Ideal for technicians performing spot weld inspections in automotive, manufacturing, and industrial applications, Echo Spot Weld™ combines precision, reliability, and ease of use for high-frequency ultrasonic testing.
