Strengthened by vibration during welding, preventing distortion and cracks
Finer metal particles improve welding strength
Prevents distortion and cracks
The argon, arc, gas or plasma welding.
Vibration applied during welding and cooling time makes crystal grain size smaller and improves the characteristics of welded portions and the vicinities, preventing internal warp and cracks and enhancing fatigue resistively.
It is a byproduct that welding is realized with less electric power if done together with vibration, consequently less preheat energy is needed and a subsequent cooling time is shortened.
