A machine to inspect spot welds using magnetism.
It is an inspection machine which can quantify the nugget of spot welding easily
Compact and lightweight sensor using magnetism measures the diameter of the nugget formed in spot welding.

Features:

1. A nugget can be quantified.
2. Can distinguish between nugget and cold-joint
(pressure weld).
3. A sensor is applied lightly and inspected.
4. High-speed inspection
(approx. 2 seconds for a single nugget.)
5. Can be used on high-tensile steel.
6. No gel or other medium required
(ultrasound method requires medium to be applied to the test object)
