Friction Stir Weld Inspection Solution

2
00:00:10,428 --> 00:00:17,643
Friction stir welding is a method that uses frictional heat created
by a rotating tool to join two parts.

3
00:00:17,643 --> 00:00:20,855
This process can introduce various flaws
at different locations in the weld.

4
00:00:20,855 --> 00:00:27,278
Voids, tunnels, lack of penatration, kissing bonds.

5
00:00:30,365 --> 00:00:35,703
Olympus gas developed a complete solution to inspect friction
stir welds in fuel tanks used by the aerospace industry.

6
00:00:35,703 --> 00:00:41,333
The system is automatically calibrated on a reference standard

7
00:00:41,333 --> 00:00:48,842
by moving the inspection head over a series of manufactured flaws.

8
00:00:53,472 --> 00:00:58,435
Once calibrated, the inspection head moves to the inspection position.

9
00:00:58,435 --> 00:01:02,813
Inspection can then be performed without
leaving traces of water on the surface.

10
00:01:02,813 --> 00:01:07,985
The inspection head design provides optimal positioning
of the phased array probes and wedges.

11
00:01:07,985 --> 00:01:11,530
PA probes can be positioned at forward, backward, clockwise,

12
00:01:11,530 --> 00:01:15,075
counterclockwies or oblique orientation to inspect
the full volume of the weld.

13
00:01:18,328 --> 00:01:22,292
Once the inspection is complete, the inspection head retracts
from the surface, ready to inspect the next weld.
