Weld Problem
Solving
Failures of
Procedure Qualification Test Plates are expensive and frustrating to a
fabricator. The cause of these failures range from simple misfits of the
plates to a bead size and sequencing issue. Materials scientists, stress
analysts, and failure analysts with hands-on experience are needed to
solve weldment problems. Daily welding problems involving visual weld
quality rejections should not be blamed totally on the welder. There may
be other causes stemming from the transfer type, position, preheat or
base metal contamination that are not readily identifiable. It can be
extremely expensive to solve these problems by trial-and-error methods.

Weld Failure
Analysis
O'Donnell Consulting provides weldment failure mode investigations using
an interdisciplinary approach using metallurgical evaluations along with
residual stress, fracture, and fatigue evaluations. Joint design, weld
metal type, process details, lack of fusion, undercutting, porosity, inclusions,
and other weldment imperfections are evaluated.
