Scanning procedure


6 SCANNING PROCEDURE

6.1 Overview

A complete plate is scanned in terms of stripes. Each stripe consists of a short and a long run.

In order to prepare the plate for testing, the usage of a shock cord with chalk is recommended to indicate the stripes with a width of 240 mm on the plate.

Proceed according to the followings steps:

1. Perform the short run first (Figure 63, stripe 1, from right to left)
2. Ensure the tracked distance is larger than the length of the trolley.
> When reaching the plate edge, the software indicates to swap to the long run.
3. When changing from short to long run, turned around the trolley (#3).
> Then the long run is performed (in below figure from left to right) and stripe 1 has been completed successfully.
4. Move the trolley backwards over a short distance to start with the short run for stripe 2.
5. Repeat the steps 1 to 5, but on the other side of the plate.

After having completed above procedure for the entire plate, you can decide whether the stripes are combined in meander-like or parallel-like pattern.

Then, a complete 2D-Scan of the plate is provided.
