Setting Up and Operating the HST-X04 Scanner 11
1. Setting Up and Operating the HST-X04 Scanner
The HST-X04 scanner is a versatile pipe and plate scanner, which can be used to
inspect welds using TOFD or pulse-echo techniques.
1.1 Description
The HST-X04 scanner is composed of two probe holders mounted on a bar. A mini-
encoder is installed on one of the probe holders (see Figure 1-1 on page 11).

1.2 Assembling the Scanner
This section presents the assembly procedures for the HST-X04 scanner, which
include installing a probe and wedge in a probe holder, installing and adjusting a
probe holder, and installing the Mini-Wheel encoder.
1.2.1 Installing a Probe and Wedge in a Probe Holder
To install a probe and wedge in a probe holder
1. On the side of the fork, unscrew the wing screw enough so that you can pull the
fork arm away from the probe holder (see Figure 1-2 on page 12).
Figure 1-2 Pulling the fork arm away from the probe holder
2. Install the probe and wedge between the two fork arms and push the fork arm in
order to place the arm guiding pin into the wedge side hole.
Before installing a new probe into a probe holder, make sure there is enough couplant
between the probe face and the wedge.
3. Screw the wing screw until it holds the fork arm tight against the holder.

1.2.2 Installing a Probe Holder
To install a probe holder
1. On top of the holder, unscrew the wing screw enough to loosen the bar socket (see
Figure 1-3 on page 13).
Figure 1-3 Loosening the bar socket
2. Move the probe holder on the bar to the desired position and screw the wing
screw tight enough to hold the probe holder in place.
1.2.3 Installing an Encoder
The Mini-Wheel encoder (see Figure 1-4 on page 14) can be installed two different
ways according to the scanning direction needed.

When the probes are perpendicular to the weld and the scanning direction is parallel
to the weld, the Mini-Wheel encoder is installed on the outside of the encoder holder
(see Figure 1-5 on page 14).
Figure 1-5 The Mini-Wheel encoder installed on the outside of the encoder holder
When the probes are parallel to the weld and the scanning direction is parallel to the
weld or when the probes are perpendicular to the weld and the scanning direction is
also perpendicular to the weld, the Mini-Wheel encoder is installed on the inside of
the encoder holder (see Figure 1-6 on page 15).

2. Slide the Mini-Wheel encoder pin into the encoder holder and secure it with the
hexagonal head screw.
1.3 Operating the Scanner
The HST-X04 scanner is designed for manual use, and is straightforward to operate.
After you have setup the HST-X04 scanner for the size of pipe or plate you wish to
inspect (see “Assembling the Scanner” on page 12), use the following procedure to
operate the scanner.
To operate the scanner
1. Hold the scanner above the inspection surface, and then align the scanner so that
the inspection area is centered between the probes.
Depending on the type of probe or transducer used, some fine-tuning can be required
to adjust the distance between probes. Also, some situations may require the surface
being inspected to be off-centered between the probes (see “Installing a Probe
Holder” on page 13).
All carbide wear pins should be flush with the wedge surface.
2. Next, push or pull the scanner in the desired inspection direction.
