2.2.3.3 Testing of weld joints
Ultrasonic testing of weld joints is widely used in all industries. Usually testing is made by angle
beam UT-probes (Table 2.2). Deposited weld metal and heat effected zone are to be tested. Ultrasonic
testing is made from heat effected zone by straight and one-time reflected beams.
Scanning of weld root must be made by straight beams of the probe. This requirement is provided
by two parameters: entry arrow and angle.

2.2.4 Connecting the probe

Caution!
To prevent damage of connectors and cables - follow the instructions below!
Used connectors in the device consist of two parts: socket (port) and the cable plug (Figure 2.1)
Method of connecting and disconnecting the plug to the socket is shown on Figure 2.2.
When connecting cable make sure that the red dot on the plug and socket are in line.
