- •
The process of nugget growth was divided into three stages.
- •
The nugget diameter increased with dynamic resistance heat raise.
- •
The nugget diameter showed polynomial relationship with dynamic resistance heat.
- •
The weld strength showed polynomial relationship with dynamic resistance heat.
- •
This study provided a method for the nondestructive examination of nugget.
