According to a direction different from the first direction (B) (e.g., its lateral) oscillating a laser beam (20), such that perforations (28) through the molten metal pool oscillation (30), when the molten metal filling aperture (28) to change the position the perforations (28).伊斯...
The results showed that laser beam oscillating welding using linear, circular and infinity paths allow to reduce the porosity of the welded joint when compared to the joint produced without beam without oscillation. Among the three oscillating paths, the infinity mode was the best in terms of ...
