A large catalog of research is available for robotic laser welding, however, there is a notable gap in understanding the unique challenges of handheld systems, particularly regarding power levels and wobble optics. This presentation will explore critical test variables for handheld laser welding, including sub-2kW laser power and transverse scanning wobble optic parameters, such as amplitude and frequency. Welds are examined by cross-sectional analysis, longitudinal section inspection, and radiographic testing. By studying the effects of these variables, we aim to inform industrial adoption of handheld laser welding with optimized outcomes.

The Effects of Critical Process Variables on Weld Quality & Mechanical Performance in Handheld Laser Welding
Handheld laser welding technology is still in its infancy but is rapidly gaining the attention of the welding industry. However, a general lack of knowledge surrounding the process currently limits widespread industrial adoption of this powerful technology. A deeper understanding of the process as a whole will enable welders and fabricators to use the technology appropriately alongside traditional arc welding processes. We will explore the effects of critical process variables in handheld laser welding including laser power, travel speed, wobble length and frequency, & filler wire diameter and chemistry, on weld quality and mechanical performance in common engineering materials such as austenitic stainless steel, low carbon steel, and aluminum alloys. Attendees will learn how to develop handheld laser welding parameters for their applications and successfully deploy laser systems in the field alongside traditional arc welding systems as another tool in their metal joining toolbox.
