Weld and Joining Processes

Metal Joining Examination
with METL

METL performs weld certification to both AMS (MIL) and AWS specifications. We can qualify weld procedures, equipment, and operators for TIG, MIG, plasma, laser, and electron-beam welding. In addition, METL performs chemical analysis of welding wire to ensure alloy compliance.

Braze and solder joints and alloys can also be examined for quality and compliance to applicable specification requirements.

Qualification

Typical qualifications are performed in accordance with aerospace standards such as AWS D17.1. Other requirements or standards can be used as well.

Design Inspection

If joint integrity is a concern, METL can evaluate fusion, penetration, and any possible defects.

Scanning Electron Microscopy (SEM)

Scanning electron microscopy (SEM) can be used to pinpoint leaks or cracks in joints. When used with EDS, problematic phases or contaminants can be identified.
