Steep flanked single bevel butt. The joint preparation of the groove has a dramatic effect on the shape of the cross-sectional area of the first-pass weld nugget. When you see a symbol that looks like a V with a stem on the bottom, each piece of metal. Best for metals 3/16 inch or less in thickness, the square butt joint is reasonably strong when not under fatigue or impact loads (Figure 1 View A). The lower left welding symbol indicates the desired fillet weld should be on the opposite side (weld symbol above the reference line). The previous article looked briefly at butt weld design where mention was made of the increased risk of producing defects as the bevel angle or the root gap is reduced. The designer is therefore required to decide whether to use a T-butt weld, a fillet weld or a combination of the two. double-bevel butt weld with broad root face. This engineering drawing present weld type symbols and fillet weld symbols. The five basic types of weld joints are the butt joint, lap joint, corner joint, edge joint, and T-joint (a variant of this last is the cruciform joint).
