Steel Structures and Welds acoustic emission testing
Is an existing discontinuity actively responding to load? Review feasibility, expected output and limitations with IAIS.
The inspection question
Is an existing discontinuity actively responding to load?
Selected steel structures, supports, welded joints, cranes and fabricated assemblies under known loads.
This page describes a technically possible application. Final IAIS service availability, procedure, personnel and equipment are confirmed only after the asset-specific enquiry is reviewed.
How this application can work
Potential acoustic sources
AE may reveal active fracture-related or frictional sources when the structural member is stressed. Loose connections and rubbing can mimic or mask defect-related signals.
Conditions required for a meaningful test
Establish load path, load sequence, structural safety, access, sensor coupling and acoustic propagation across joints. AET is not a direct weld-volume examination.
What the client can receive
Time and location-correlated source activity within the validated zone and a targeted inspection plan.
Limits and follow-up
Use UT/PAUT, MT/PT, dimensional checks and structural assessment to identify and size a suspected discontinuity.
From enquiry to project scope
Send the asset drawing and material specification, operating and design data, previous inspection records, suspected mechanism, available access, proposed test window and applicable client or regulatory requirements. A feasibility review can then establish sensor coverage, loading or monitoring conditions, background-noise controls, procedure, evaluation criteria and the role of complementary inspection.

Acoustic emission testing in industrial environments
Sensor placement, test conditions and data acquisition are planned around the specific asset and inspection objective.
Discuss your inspection objective
Send the asset type, location, operating conditions and proposed loading or test window. We can review the information before defining a project-specific scope.
