Abstract
The American Welding Society celebrated its 100th anniversary in 2019. At this 101st year of the Society, it is particularly fitting to look back on the progress of welding development during this first century. Welding technology - process development, automation and quality assessment have all undergone great leaps. As example, new wave form-controlled power sources have been developed, from the typical constant voltage, constant current powers sources, to deliver smooth metal droplet into the weld pool. This technology has expanded the possibilities of welding dissimilar metals systems and reactive metals. Sensor technology development greatly assisted the development of virtual welding training systems as well as welding automation and robotics. Welding training has become more practical. Robotics and welding automation development has led to weld production and productivity enhancements. Many of the manufacturing facilities have introduced robotic welding and automated systems.
With the advances in welding technology, new materials have also been developed with better properties and performance. Light-weighting and energy (fuel) saving are the two top demands in structural fabrication and manufacturing. Additive manufacturing (AM) has experienced great attention and progress in the past decade, evolving from a “precision welding” situation to full manufacturing technology. This presentation will discuss the evolution welding technology experienced in the last 100 years and present an outlook of what is to come in the next decades. |
