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.

Abstract: Embodiments of an automatic girth fitter system use a device or devices to automate the alignment of horizontal weld seams in both shop- and field-built tanks or vessels. The automated system device or devices may also be used to remove shims that are used to gap the horizontal weld seams and provide plate alignment prior to fitting or welding those seams.
