Nugget Profiler, product backgroundThe 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
Merit of Nugget Profiler
Performs inspection giving no external damage to the subjects.
It has the function of quality traceability.
It can inspect even high-tensile steel.
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.
