1. An Introduction to Ultrasonic Weld Testing. 2. The Fundamentals of Ultrasonic Weld Testing.

1. High strength steels in Automotive. 2. Chisel check method and high strength steel.

High strength steels are stronger but lighter than the mild steel traditionally used in automotive manufacturing. A lighter body makes for a more fuel efficient vehicle..

In this example the passenger compartment is reinforced with high strength steels. Preventing the compartment from being crushed during impact.

The Chisel Check Method and High Strength Steels.

The most common method used to test weld integrity is the chisel check method.

ATTENTION Welds designated as ultrasonic tested (UT) hit with a chisel must be immediately reported to your Team Leader for repair (BW-DOC-ENG-34) Failure to report this issue could result in quality concerns or serious injury to our customer.

Ultrasonic testing (UT) works by using a probe to send ultrasonic sound through the material being tested. The echo from that ultrasonic sound is then received by the same probe and turned into wave shapes..

1. The Tessonics F2. 2. Necessary Conditions for Accurate Ultrasonic Scanning.

The Tessonics F2 is one of the ultrasonic units currently approved for ultrasonic scanning at Toyota (BW-DOC-ENG-34) (Q-3-5-7).

Necessary Conditions for Accurate Ultrasonic Scanning.

Reaction Plan for Ultrasonic Scanning. 1.Visual inspection of the welds being scanned..

Before beginning the weld inspection visually inspect the weld for any defects (CBIS 910) that exceed shipping standard such as but not limited to.

Welds that are uneven or that have burrs within shipping standard may be difficult or impossible to scan.

Before scanning any weld you must apply the couplant gel to scanning surface. The gel can be applied to the surface of the weld being tested or the shoe face.

Now that the welds and probe have been inspected you are ready to begin scanning.

Before scanning a weld the Tessonics units require that you determine the thickness of the front sheet that the weld is on. This is done by taking a scan of an unwelded portion of the front sheet.

The green in the image represents bonded material beyond the front sheet.

The unit converts the information from the image into numerical data.
