QC Inspection & Testing

Our inspection and testing processes meet and exceed customer expectations

Inspection

Every expansion joint passes through a variety of inspection points, from Initial Material Inspection to In-process Inspections to Final Inspection. Receiving inspections are the first stop for any material that arrives in our shop. This inspection verifies that the material we receive is correct per the purchase order information. In-process inspections are performed throughout the entire manufacturing process. Manufacturing hold points that are mandated with the inspection traveler, as well as spot checks by quality control inspectors, assure each part is fabricated to the individual job specifications.

Final inspection is performed by a quality control inspector on all expansion joints prior to shipment. The level of final inspection required is typically dictated by the customer or the actual manufacturing code specified. Badger is an advocate for continuous improvement of safety, fabrication, and inspection practices. We constantly strive to develop safer and more efficient manufacturing and inspection procedures.

Testing

Non-destructive examination capabilities include:

Fluorescent Dye Penetration Inspection
A type of dye penetrant inspection in which a fluorescent dye is applied to the surface of a non-porous material in order to detect defects that may compromise the integrity or quality of the part or weld in question.

Liquid Dye Penetration Inspection (Visible Dye) 
A type of dye penetrant inspection in which a red visible dye is applied to the surface of a non-porous material in order to detect defects that may compromise the integrity or quality of the part or weld in question.

Radiographic Inspection (RT)
Non-destructive testing (NDT) method of inspection used for detecting the presence of sub-surface discontinuities in welds and parent materials through the use of radiography.

Magnetic Particle Inspection
A non-destructive testing (NDT) process for detecting surface and slightly subsurface discontinuities in ferromagnetic materials and welds by direct or indirect magnetization.

Ultrasonic Inspection (UT)
Non-destructive testing (NDT) process for detecting internal flaws in welds and parent materials through the use of ultrasonic waves.

Pneumatic Pressure Test Inspection
A non-destructive testing (NDT) process in which pneumatic (air) pressure is applied in the expansion joint. This is to test the structural integrity of the basic design of the expansion joint assembly and detect discontinuities in welded or parent metal which extend through the entire material thickness which would allow a pressure decay to occur.

Air and Soap Leak Test
A process for testing the pressure integrity of welds in a low-pressure expansion joint assembly.

Hydro Pressure Test Inspection
A non-destructive testing (NDT) process in which Hydrostatic (water) pressure is applied to the expansion joint. This pressure tests the structural integrity of the basic design of the expansion joint assembly and detects discontinuities in welded or parent metal which extend through the entire material thickness which would allow a pressure decay to occur. 

Helium Mass Spectrometer Leak Detection
A process for testing the pressure integrity of the expansion joint using helium gas.

Positive Material Identification (PMI)
An examination to determine the identification of material actually used in the expansion joint by using X-Ray fluorescence to identify materials specific grade name and quantitatively report their chemical compositions.
