What Factors Affect PAUT Probe Selection?

1. Material type (carbon steel, stainless steel, aluminum, composite materials) 2. Part thickness 3. Expected type of defect 4. Type of inspection (weld inspection, corrosion, forged parts, cast parts)

Is a Higher Number of Elements Always Better in PAUT?

No. A higher number of elements usually offers technical advantages, but the probe and equipment cost is higher, the amount of data increases, and not all devices support probes with a large number of elements.

Why Stress Relief Matters

If stress relief (PWHT) is not carried out after welding, the weld and the part are exposed to various mechanical and metallurgical issues that usually manifest sooner or later. In short: a weld without stress relief is like a compressed spring that may release at any moment.

The Importance of Preheating

If preheating is not done before welding, the most important consequence is increased thermal stresses and the formation of severe weld defects. In short: cold metal cannot withstand thermal shock and will crack.

Results of Stress Relief Testing (PWHT)

Stress relief by controlled heating of the part (typically 550 to 650 degrees for steels) results in: reduced residual stresses, a more stable microstructure, and predictable part behavior in service.

How Does Phased Array Work?

In this method, instead of using a single ultrasonic crystal (conventional ultrasonic testing), an array of small elements is used. By controlling the pulse timing sent to each element, the device can change the beam angle, scan the beam without mechanical movement, and focus at different depths.
