Overlap?
How would you call it when found on a part that you were inspecting? This has created much debate in my world and I’d like to hear some other opinions.
(I’m not picking on Kix, I understand the weld was made to explore the PT question.)
The picture from Kix’s post on Fluorescent dye check issues GTAW on 6061-T6 using ER4043
https://www.aws.org/cgi-bin/mwf/topic_show.pl?tid=33191 This clearly shows overlap at the start and termination of the weld, Based on the AWS Official Interpetation.
"Subject: Overlap at the ends of Welds
Document: A3.0M/A3.0:2010, Standard Terms and Definitions
Provision: Page 30, Definition for overlap, fusion welding
Page 47, Definition for weld toe
Inquiry: Due to the absence of discussion and figures related to weld end-conditions, it is unclear whether requirements for overlap are applicable at the ends of a weld bead, where the arc starts and stops.
Response: The overlap condition (as currently defined) does apply to the ends of welds, not just the sides which are illustrated in the referenced figures."
