ASME helps the global engineering community to develop solutions for real world challenges. The company ASME was established in 1880 as American Society of Mechanical Engineers. It is a non-profit professional organization that enables the cooperation and the exchange of knowledge and professional skills in all technical fields. Moreover, it reinforces a crucial role of engineers in the society. Subsequent ASME codes and standards, its publications, conferences, continuous education and professional development programs represent foundations for the expansion of technical knowledge and a safer world.
