What is testing weld of ultrasonic?

Ultrasonic testing of welds involves using high-frequency sound waves to detect flaws or discontinuities in the weld material. This non-destructive testing method can help identify structural defects such as cracks, porosity, or lack of fusion in the weld joint. Ultrasonic testing is commonly used in industries like construction, manufacturing, and oil and gas to ensure the integrity and quality of welds.
