Magnetic Particle level II & III
Magnetic particle inspection is used to inspect steel parts for defects. It is used in production and in service inspection. It uses magnetism in different direction and different intensity to inspect parts.
Penetrant II & III
Penetrant inspection is a inspection technique used for detection of surface defects for metallic and non metallic parts. Cracks, laps, holes and leaks can be easily detected.
Ultrasonic II & III
Ultrasonic inspection is mainly used for weld and thickness testing but is also used widely for testing of composites for bonding properties. Sound is induced into the part at different angles depending on the inspection to identify if any defects are present.
Eddy Current II & III
Eddy current inspection is used mainly as a surface/subsurface inspection to identify cracks in thin metalic and nonmetallic parts. Common inspections used are for aircraft surfaces and chiller tubes.
Visual II & III
Visual Inspection is the most common inspection performed. All inspections start with a proper visual inspection. Visual inspection involves determining if the part is ready for inspection, conforms to specifications and meets requirements such as prints.
Welder Certification And Qualification
Welder certification and qualification is just what it says. It is the process of evaluating a welders technique and quality as compared to written industrial requirements first by visual inspection then followed by other destructive testing as required such as bend, X-ray, metalgraphic, etch, or tensile. All to attest to the fact that the welder can weld to a certain quality level. For more on Welder Certification, Weld Inspector Certificaton, abd Welding Procedure Writing, go to our Welding page.
Welding Procedure Writing
Each welder must weld according to a established procedure. In order to be a qualified procedure the welder must have his technique qualified. This requires visual and destructive tests to verify the strength requirements of the metal is met. The welder supplies a welded plate or pipe for this testing.
Certified Weld Inspection (CWI and CAWI)
Welding inspectors are required to be certified to inspect welds. The most popular and widely accepted certification is that through the American Welding Society. They certify inspectors and educators through classes and certification testing for those who can qualify to experience requirements.
