Allied-Signal Aerospace Company wanted to eliminate destructive testing. To get approval, they conducted capability testing utilizing a WeldComputer Control. The study demonstrated that the capability of the tested material far exceeded the required 99.5% level and approval was granted to eliminate destructive testing. For details, read the study.
This report establishes that the resistance welding process, as controlled and monitored by WeldComputer’s equipment, is sufficiently reliable to allow the substitution of nondestructive evaluation for destructive testing.
When performing resistance welding, electrode force impacts the size and strength of the welds produced. This force is controlled by differential cylinder pressure, meaning that monitoring this variable is another way to indirectly monitor the electrode force. This MIL-SPEC aluminum resistance welding manufacturer was seeing cracks in their welds and had been struggling with the […]
