文摘
- •
Beam oscillation stabilizes the process and improves weld morphology.
- •
Beam oscillation increases the fraction of equiaxed grains in weld fusion zone.
- •
Beam oscillation has no effect on weld strength but obvious effect on elongation.
- •
Circular oscillation obtains the soundest weld with the best mechanical properties.
- •
Mechanism is discussed by the stirring effect on laser keyhole and melt flow.
