Continuous production monitoring
In continuous production monitoring, visual inspection of all welded studs is typically sufficient. On suspicion of
a faulty weld, a bending test or a tension test must be carried out.
If the requirements are not met, a bending or tension test must be carried out on the 2 previous welds and on
the 3 subsequent welds. The test results must be recorded in the production log.
It must be noted that the welding work may only be continued when the test
results are satisfactory.
5.7.1 Short Cycle Method - Visual Inspection
Inspection and testing of the weld is restricted in this manual to the visual inspection of welds. A description of
the mechanical and technological tests involved would go beyond the scope of the manual.
