What is weld testing method?

Weld testing and analysis Imaging-based methods. X-ray-based weld inspection may be manual, performed by an inspector on X-ray-based images or video, or automated using machine vision. Ultrasonic- and acoustic-based methods. Ultrasonic testing uses the principle that a gap in the weld changes the propagation of ultrasonic sound through the metal. Peel testing of spot welds.

How can I assess the weldability of a material?

Part of determining weldability is calculating the carbon equivalency (CE) of the base materials, often using the following CE formula: CE = C + (Mn + Si) / 6 + (Cr + Mo + V) / 5 + (N i+ Cu) / 15. The CE helps you determine cracking susceptibility as well as the necessary preheat and interpass temperature controls.
