Reinforced steel joint inspection

The inspection methods using ultrasound vary by joint construction method! Here we introduce cases of pressure welding, welding, and mechanical methods.

The "Reinforcement Joint Inspection" involves conducting visual inspections and ultrasonic testing (or measurement) as part of quality control for reinforcement joints. The ultrasonic testing method varies depending on the joining method. In the case of pressure welding or welding, ultrasonic waves are directed into the rebar, and defects in the joint area are detected through reflected waves from those defects. For mechanical joints, ultrasonic measurements are used to verify whether the rebar is inserted to the correct length in the coupler or sleeve. Additionally, after the swelling of the pressure-welded joint is removed, we conduct "Hot Extrusion Inspection" to check for cracks, dents, surface irregularities, and to measure the swelling length using calipers or scales.
