摘要： A welding apparatus for use in welding first and second sheets of material together includes a seal die, a platen, a control unit, and a power source adapted to provide energy to the seal die. The seal die is made of a conductive material and is configured to impart thermal-mechanical energy to the first and second sheets of material. The seal die includes a bottom surface configured to contact the first sheet, an inner edge, a chamfer extending between the bottom surface and the inner edge, a first blend radius, and a second blend radius. The first radius extends between the chamfer and the bottom surface, while the second radius extends between the chamfer and the inner edge. The platen is configured to support the second sheet, while the control unit is programmed to cause the seal die to be directed towards the platen.
