The invention provides a sonotrode (100) for welding a material, the sonotrode (100) comprising a welding section (110) configured for contacting the material, wherein the welding section (110) defines a rounded shape (111) in a cross-section parallel to a longitudinal axis (A) of the sonotrode (100), wherein the rounded shape (111) approximates a circular sector (20), wherein the circular sector (20) has a central angle αc selected from the range of 25°-300°, and wherein the circular sector (20) has a central radius rc selected from the range of 5-30 mm, and wherein the sonotrode (100) has a width W perpendicular to the longitudinal axis (A) [and to the cross-section], wherein W is selected from the range of 10-100 mm.
A sonotrode (100) for welding a material (10), the sonotrode (100) comprising a welding section (110) configured for contacting the material (10), wherein the welding section (110) defines a rounded shape (111) in a cross-section parallel to a longitudinal axis (A) of the sonotrode (100), wherein the rounded shape (111) approximates a circular sector (20), wherein the circular sector (20) has a central angle αc selected from the range of 25°-300°, and wherein the circular sector (20) has a central radius rc selected from the range of 5-30 mm, wherein the sonotrode (100) has a width W perpendicular to the longitudinal axis (A), wherein W is selected from the range of 10-100 mm, and wherein the sonotrode is functionally coupled to a consolidator (200), wherein the consolidator (200) is arranged downstream from the sonotrode (100) at a distance d1 from the sonotrode (100), wherein d1≤5 cm.
A method for welding a material using a sonotrode (100), wherein the method comprises:
A sonotrode (100) for welding a fiber-reinforced polymer composite material (10), the sonotrode (100) comprising a welding section (110) configured for contacting the fiber-reinforced polymer composite material (10), wherein the welding section (110) defines a rounded shape (111) in a cross-section parallel to a longitudinal axis (A) of the sonotrode (100), wherein the rounded shape (111) approximates a circular sector (20), wherein the circular sector (20) has a central angle αc selected from the range of 25°-300°, and wherein the circular sector (20) has a central radius rc selected from the range of 5-30 mm, wherein the sonotrode (100) has a width W perpendicular to the longitudinal axis (A), wherein W is selected from the range of 10-100 mm, wherein the sonotrode (100) is configured for applying a pressure selected from the range of 15-100 MPa, and wherein the sonotrode is functionally coupled to a consolidator (200), wherein the consolidator (200) is arranged downstream from the sonotrode (100) at a distance d1 from the sonotrode (100), wherein d1≤5 cm.
