摘要： A forming system includes a femtosecond laser and a control unit that includes one or more processors operatively connected to the femtosecond laser. The femtosecond laser is configured to emit laser pulses (302) onto an inner surface (218) of a face sheet (134) of an acoustic inner barrel (120). The acoustic inner barrel (120) includes an acoustic core (128) comprising an array of hexagonal cells attached to an outer surface of the face sheet (134) that is opposite the inner surface (128). The control unit is configured to control the femtosecond laser to laser drill a plurality of perforations (150) in the face sheet (134) via emitting laser pulses (302) at pulse durations between about 100 femtoseconds and about 10,000 femtoseconds and at frequencies over 100,000 Hz such that the perforations (150) are formed without burning portions of the face sheet (134) or the acoustic core (128) surrounding the perforations (150).

摘要： The invention provides a welded member including a hot dip Zn-based alloy coated steel sheet as a base material and has excellent corrosion resistance and weld bead shear strength, and provides a method for manufacturing the welded member. In a welded member (10) in which a lower sheet (3) and an upper sheet (1), which are hot dip Zn-based alloy coated steel sheets, are stacked and arc-welded together, a weld bead (2) is formed so that a cross-sectional width W satisfies the following formula (1) and a blowhole occupancy Br represented by the following formula (2) becomes not more than 50%: 2T ≤ W ≤ 6T (1), Br = (∑di/L) × 100 (2), where T represents a thickness of hot dip Zn-based alloy coated steel sheet, di represents a length of i-th blowhole observed in X-ray radiography, and L represents a length of weld bead.
