Certified Welding Inspection in Detroit: what to expect
Certified welding inspection in Detroit gives owners, contractors and engineers an independent check that welds meet the drawings and the governing code. The most recognized credential is the American Welding Society Certified Welding Inspector (CWI). Inspectors review welding procedures and welder qualifications, check fit-up, watch welding in progress and inspect finished welds.
Visual inspection is the base of every program. When the specification calls for it, inspection firms add nondestructive testing such as magnetic particle, dye penetrant, ultrasonic or radiographic testing. Commercial buyers across Detroit, Southfield, Warren and Auburn Hills use CWIs for structural steel special inspections, pipe welding, fabrication shop audits and supplier quality checks.
Inspection pairs with structural welding and pipe welding. For welder test certification, see pipe welding certification. Compare welding pros in Metro Detroit.

Codes, permits and certifications
On commercial projects under the Michigan Building Code, the building official and engineer of record may require special inspection of structural steel welding, and the owner typically hires the inspection agency. Confirm the requirements with the building department (BSEED in Detroit) and the engineer before work starts.
Ask for the inspector's AWS CWI certification number and confirm it with the AWS certification search, and ask about nondestructive testing personnel qualifications if testing is included.
