A Hand-Held Flaw Detector for Testing Spot Welds in Situ on the Production Line
The range of joining methods used in automotive body assembly lines has significantly increased in the last few years. While formerly, resistance-welding and MIG/MAG welds were the preferred joining methods, techniques such as laser welding/soldering, bonding, etc, are also in common use today. Since all of these processes can be used singly and sometimes all together, this complexity places new demands on test engineering. In addition to destructive testing of spot welds, i.e. with a hammer and chisel, nondestructive testing with ultrasound has become routinely applied in recent years. The increased acceptance of this procedure is due in no small part to the decisive advancements contributed by GE Sensing & Inspection Technologies, working in close cooperation with the automotive sector. Today ultrasonic spot weld checking is a technique employed by major car manufacturers. The SpotChecker allows to take spot weld checking right onto the production line, saving time – and money.
