The systems use a portable support platform that can be easily transported to different welding stations/sites, providing a marked advantage over legacy monitoring systems that use heavy welding stands that are difficult to move. After an initial calibration, the systems can consistently and repeatedly monitor welding technique relative to a particular joint with no additional calibration necessary, even if there is sensor and/or platform movement. The systems are additionally able to detect a welding-type operation without the need to communicate with welding equipment. The systems are further configured for use with existing (rather than potentially expensive custom) welding-type tools, thereby keeping the systems low cost and highly portable.
