Problem
Plaintiff's counsel needed an independent metallurgical expert on a personal-injury case where a welded steel frame allegedly collapsed under nominal load.
Approach
Chain-of-custody sample intake; macro + micro examination of the failed weld; hardness surveys across the HAZ; comparison to AWS D1.1 acceptance criteria; written report + deposition + trial testimony.
Finding
Weld exhibited undercut + lack-of-fusion on the loaded toe, well beyond D1.1 limits. The parent metal was compliant; the welder qualification records were incomplete.
Outcome
Case settled favorably for the plaintiff two weeks before trial. Report and testimony were entered into evidence without objection.
