Abstract
Embodiments of an automatic seam fitter attachment for use with an automatic welding machine are designed to automate the plate edge cleaning, tight seam fitting, and tacking or welding of metal lapped or butted plates. The seam fitter attachment can be used on any product or in any industry where metal lap or butted plates seam together. The attachment may be provided with a power cleaning brush that cleans the edges of the plates and mechanically forces plate tightness as they are being tacked or welded.
