Title: John A. Molnar: Innovator in Thermoplastic Welding
Introduction
John A. Molnar is a notable inventor based in Dublin, OH (US), recognized for his contributions to the field of thermoplastic welding. With a focus on developing processes that enhance the efficiency and effectiveness of welding large structures, Molnar has made significant strides in this specialized area.
Latest Patents
Molnar holds a patent for a process that enables the creation of long, continuous thermoplastic welds on large structures. This innovative method utilizes a series of tabs in pairs, particularly in alternating, overlapping pairs, to achieve resistance heating of a strip material placed in the bond line. The resistance of the tabs is designed to be less than that of the strip material, allowing for effective welding. Additionally, conducting braid-tubes facilitate continuous welding even when the bond line is curved. Alternatively, an electromagnetic field can be employed to leverage induction heating, utilizing a wide susceptor to weld a current-conducting substrate while minimizing bulk heating. A unique property of current-conducting braid-tube susceptors allows induction heating to occur at the center rather than at the edges, enabling the production of long, continuous curved welds.
Career Highlights
John A. Molnar is associated with the Edison Welding Institute, Inc., where he has applied his expertise in welding technologies. His work has contributed to advancements in the field, particularly in the development of innovative welding techniques that improve the quality and durability of welds in large structures.
