A method for manufacturing a laminated structure for use in an absorbent article such as a diaper, a sanitary napkin, a panty liner, an incontinence pad or similar and being defined by a plurality of material layers comprising at least a first layer which is liquid-permeable, a second layer constituting an absorbent core and a third layer, each of the layers being formed of a material having a certain pore radius. The method includes bonding together the material layers by means of at least two ultrasonic welding steps; and providing an ultrasonic welding pattern for each of the welding steps, each of the welding patterns being defined by a plurality of bonding sites. The method includes providing the welding steps for forming generally the entire absorbent article; and selecting the welding patterns in a manner so that at least the entire laminated structure has a multiple pore radius.
