I did not see this posted on the site anywhere, I thought I would bring this to the forum member's attention:
DSA's investigation of defective tube steel, or Hollow Section Steel (HSS) as it is also called, continues. DSA Bulletin BU 07-03 has been updated and posted to the DSA Web site, Publications page and Testing Labs page. Pictures of some defective welds found (as well as a good seam weld for comparison purposes) can be found on the Testing Labs page.
