Abstract
Some examples include a computing device that receives optical signal information based on respective optical signals received through a plurality of optical fibers during a welding operation. For example, the plurality of optical fibers may be positioned to receive electromagnetic radiation from a weld area during the welding operation. The computing device may compare the optical signal information corresponding to a first one of the optical fibers with the optical signal information corresponding to a second one of the optical fibers. Based at least partially on the comparing, the computing device may determine whether at least one of a weld geometry or a welding arc is irregular. The computing device may perform at least one action based on determining that at least one of the weld geometry or the welding arc is irregular.
