Magnetic Particle Dimensional Checking Radiographic Inspection Ultrasonic Inspection

Magnetic Particle Testing

    As castings are processed in the cleaning room, several non-destructive testing methods are used in the inspection process. At some point in the process each casting goes through 100% magnetic particle inspection. Harrison Steel has 11 dry powder and 3 wet-magnetic particle inspection stations.

Dimensional Checking

 

Harrison Steel’s layout department is housed in a 1370 square foot facility built in 1982.  It is capable of handling castings up to 12,500 pounds.  A certified layout person performs dimensional testing on all new pattern equipment, sample parts and periodic production audits.  The facility houses 2 Bendix Portage Layout Machine (Model 60A) that sit atop a 5-section layout table.  Each machine has a 25” multi axis rotary table.  The tables are able to handle castings up to 4000 pounds.  Machines are able to check a 60” (3048mm) x 92” (2337mm) envelope with the aide of the rotary table.  Tolerances on these two machines are ±.004”.  In addition to the Model 60A, the facility also has a model 84A.  This sits atop a 6-section table.  The tables are arranged to provide an 11.5’x12. 5’ works surface.  This allows us to check an 84” (2134mm) x 100” (2540) envelope.  Tolerances on this machine is also ±. 004”.

 

Radiographic Inspection


Harrison Steel maintains one of the industry's top Radiographic Inspection Facilities. Built in 1989, the facility contains over 3,900 square feet of space. Two exposure vaults, measuring 15'8" x 17'5", provides plenty of space to gamma ray large parts with ease. Harrison Steel's facility has 3 radioactive isotopes. One vault contains a cobalt 60 source and an iridium 192 source, while the other contains another cobalt 60 source. Film is developed in-house with the use of an automatic film processor.
