Flush Finish – This symbol explains what we need when finishing the process. M: Machining Finish. Finish symbols go above the reference line to indicate the surface contour or finish of the weld such as flush, convex or concave. e. The surface should be in a straight line with the level of the plate. Each welding symbol has two segments: a horizontal reference segment and a leader. You probably could have thickened the weld so you would have more to grind down. The choice of the type of corner joint weld to be chosen for an application depends on the thickness of the parts involved, and the strength specified by the design for the joint. complete joint penetration groove weld.
