Bliss, NY Visual Testing (VT)
Probably the most important inspection technique and one we are gifted with is visual testing with our eyes. This is a very common, low cost, quick and effective way to inspect welding, equipment, and coatings. Visual testing is the most important tool for a Certified Welding Inspector (CWI), It’s a certification you can acquire through ASNT or with your company by ASNT TC 1A. Defects commonly found using visual inspection is excessive reinforcement, underfill, undercut, porosity, cold lap. If able to access the inside or root of the weld its possible to see lack of fusion, or incomplete penetration.
Traditional Film, Computed Radiography and Digital radiography in Bliss, NY
Integrity Testlabs currently utilizes traditional film and computed radiography (CR) film. Traditional film is still loaded under safe lights and developed using a 5-step process in the back our darkrooms. Once dry, the filmed in viewed under a high intensity viewer looking for defects. Traditional film comes in several different sizes and leaves the client with a physical piece of film to view for years to come. Computer Radiography or CR uses plates that are phosphor. When these plates are exposed to radiation, the plates emit a blue light that is interpreted by the film processor and then transmitted into an image and viewed on the computer screen. This process is efficient and plates can be used multiple times, no chemicals are needed to process the film. Digital radiography is newer to the industrial and keeps gaining popularity each year. Limited in film size and mobility. The biggest advantage is shorter x-ray times, less radiation, wire or wireless capabilities, and instant images that are displayed on the computer screen.
Eddy Current uses electromagnetic induction with alternating currents passed through a coil. The coil produces alternating magnetic field. Used extensively in the aircraft industry and manufacturing industry to look for surface and subsurface defects. Also used in the Nuclear and Petro chemical industry on heat exchanger tubing. When the surface is properly cleaned Eddy Current (ET) can be a fast and very effective Nondestructive inspection.
Bliss, NY American Welding Society (AWS)
Founded in 1919 the American Welding Society (AWS) is a nonprofit organization that is made up of members and panels of members. They are yearly contributing to advancing the science, technology, and application of welding and allied joining and cutting processes worldwide, including brazing, soldering and thermal spraying. Many well-known certifications come from AWS. The CWI or Certified Welding Inspector is one of them. Integrity Testlabs has in house and contract CWI qualified workers to meet the need of any project.
ACFM; Alternating current field measurement in Bliss, NY
Integrity Testlabs was one of the first companies to provide this inspection technique in the Northeast. ITL technicians have completed hundreds ACFM inspections on equipment shells in oil refineries in the Northeast. ACFM is a electromagnetic technique used for detecting cracks breaking the surface. Capable of also sizing the defect. ACFM can be used on ferrous and nonferrous metals. ACFM can be fast and effective inspection. It does need the area to be cleaned and electric available to run the ACFM unit. Wet Fluorescent Magnetic Testing (WFMT) can be used as an alternate inspection to confirm the findings of the ACFM.
