In this session, we introduce a novel and evolving fabrication technique: Handheld Laser Welding. We will review its differences as compared to traditional welding methods with examples of handheld laser applications including welds up to 3/8 inch thick in stainless steel, as well as mild steel, aluminum, copper, titanium, and nickel alloys. We will review pertinent topics such as handheld laser welding safety and standards as well as additional capabilities such as surface cleaning and passivation. Lastly, we will highlight current trends and outlook for this technology.

Handheld Laser Welding Advancements and Comparisons to Traditional Welding Processes
Recently, handheld laser power sources and relevant PPE products are attracting more attention in the welding world. Compared to traditional TIG or MIG welding, handheld laser welding has unique process benefits including: higher controllable penetration, less heat input, a better gap bridging ability and higher travel speeds - all without arc blown effects. Moreover, handheld laser welding reduces the complexity of operator training and could be applicable to additional on-site welding applications due to the compact air-cooled power source design and overall portability of the laser welder system. A comprehensive overview on handheld laser welding product design, PPEs, and the relevant process development data will be compared to automated laser welding, TIG and MIG processes and their main industrial applications within the manufacturing world. Additionally, the latest developments of new standards for handheld laser safety, training of operators, and process development via the AWS C7 committee will be included.
