The butt joint occurs when two members are placed side-by-side or butted together. The weld is made along the seam that adjoins the two adjacent pieces. Depending upon the thickness of the materials, the edge of the butt joint maybe squared, beveled or have some other type of preparation done to it prior to fit up and welding. The butt joint can be welded on one side or both sides depending upon the requirements in the drawing or welding symbol. The butt joint is considered a groove type weld.
