Nugget Profiler, product background
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

The problem of a driver check
usually steel (270MPa,440MPa); A bend arises around a nugget and metal fatigue occurs.
high-tensile steel(780MPa or more); It cracks on a nugget or the outskirts of it.
For the reason, welding intensity falls.
