Torque Testing Device


Non-destructive test method for studs welded with tip ignition (CD) and short cycle (SC) process. Torque check of the welded studs for quality assurance. With this tool you can make a fast and easy, non-destructive stud test. A quantitative check of the welding quality in line to ISO 9000ff can be made.

A bending torque is applied by a torsion meter onto the stud. This applies a defined stress in the welding zone. The test torque parameters are shown in a table included in this test kit. You can edit the torque at the torque wrench by turning the set-up wheel (2 – 10 Nm). Each parameter from the table belongs to the specified stud diameter, the specified material and the sheet thickness of the work piece. These empirical parameters refer to the limit between the elastic and the plastic deformation of the stud or the work piece. For a ratio stud diameter to work piece thickness smaller than 1:2 a plastic deformation of the work piece will occur; for ratios larger than 1:2 the stud will fail.
