Weld Overlay
Weld Overlay is a standard inclusion on the EPOCH 1000i, pro‑
viding a visual reference of a weld profile on the S‑scan display.
This profile enables you to visualize the relative position of indi‑
cations in relation to the weld geometry.
A weld centerline cursor allows manual positioning of the overlay
on the S‑scan. The Weld Overlay enhances your ability to locate,
characterize, and size flaws within the component during inspec‑
tion, and improves reporting.
EPOCH 1000i Multi-Angle
The EPOCH 1000i phased array mode includes a standard feature
called Multi‑Angle. This feature enables you to designate any
three angles, or focal laws, available in the sector scan as “vis‑
ible” focal laws. The A‑scans from each of the three designated
angles are overlaid, one on top of the other in the A‑scan window,
enabling you to view all three A‑scans at the same time. Each
individual angle is color coded for ease of use. This feature is
perfect for inspectors using conventional sizing methods requiring
evaluation at 45°, 60°, and 70°.

AWS “D” Weld Rating displayed for 45° focal law A-scan and S-scan view with True Depth Gates
True Depth Gates
Measurements gates can be displayed in True Depth mode on the
Sector Scan, thus enabling you to acquire measurements from a
constant depth area throughout the part, regardless of the focal
law selected. This is particularly helpful when using the encoded
C‑scan option, as it enables you to collect information for one
entire skip distance with a single gate position.
The True Depth gates display as horizontal lines on the S‑scan
only; the A‑scan view remains in Soundpath mode.
AWS Weld Rating
The EPOCH 1000i comes with an AWS D1.1/D1.5 weld rating
calculator. In conjunction with Olympus’ AWS‑rated phased
array transducer, this enables you to use imaging capabilities for
flaw detection while sizing flaws at 45°, 60°, and 70° using the
conventional A‑scan technique, and also view the D value for
onscreen weld rating of any selected A‑scan (focal law).
