Welding jobs that are not automated often pose particular challenges in their execution, due to not only the geometry and position of a welding bead to be produced but frequently also the required job steps and precision of execution. For small series production, this means that much more information is needed for each welding step. Even for welding professionals, this is a huge challenge that demands much time and also proves error-prone.
For this reason, SCCH has researched interaction possibilities in a joint project with an industrial partner. Here we used an approach called Human Centered Software Engineering (HCSE) to ensure that the results would be useful in practice and decisively support users in their work.
In initial studies of the work process, we quickly came to a preliminary decision. Due to the particular conditions involved in welding and the limited interaction options with hands shortly before or during the welding process, we opted for information representation and interaction with Augmented Reality (AR) in order to display additional information in the work environment.
Our concrete solution encompasses two areas: information on the job order and configuration of the power source (welding device). Information about the current job order requires the availability of corresponding data, including preparations (type of metals, distance between metals, check of the geometry of the welding gap) as well as the welding process itself (welding position, welding material, required settings of power source, welding direction, welding speed and cooling phase). This information is displayed for the workpieces and optically linked to reduce errors. All parameters of the power source can be configured with the AR goggles; the welder no longer needs to move to the power source.
In our first step, we did not consider the suitability for series production of the hardware; the primary goal was to develop the interaction, not the hardware.
