Latest Patents

Maciel's latest patents focus on friction plug welding methods and systems. These methods involve plugging a hole that extends through a component part from both the front and back faces. A sacrificial plate with an opening may be positioned against the back face of the component part, ensuring that the opening is coaxially aligned with the hole to be plugged. By advancing a male plug of a plug rod into the hole under friction plug welding conditions, a friction weld region is formed between the male plug and the defining surfaces of both the hole and the sacrificial plate. The design includes an annular shoulder flange that defines a plane parallel to the front face of the component part, allowing for effective displacement of flash flow from the friction welding process. The male plug may also feature a frustroconical shape, enhancing the efficiency of the welding process.
