Nugget Profiler
NPH02
The conventional quality control of spot welding,

Guarantee of quality => Breaking test
Quality identification => Driver check (DC)
The inspection method replaced with this Driver check (DC) is proposed. Practical application of non-destructive inspection using magnetism.
A nugget can be quantified.
Applicable cases - shipping inspection

The nugget profiler can be used at parts companies.

All parts in a production lot are quantified: Variations in the lot can be confirmed.
Then, a single piece can be sampled out of the lot and subjected to breaking test to assure the quality.
Note: The Outflow Of Defective Parts Can Be Prevented.
(Parts other than those subjected to breaking test can also be checked for quality.)
