9 Weight
Per Foot of Weld Metal for Fillet Welds and Elements
of Common Butt Joints (lb/ft) Steel Instructions
1. Make a drawing of the
cross-section of the joint to exact scale. 2. Divide
the cross-section into right triangles, rectangles and sketch
in the desired reinforcement. 3. Measure
the thickness, angles angle leg lengths, root opening
and the length and height of the reinforcement.
4. Total the weight per foot
of each of the elements from the chart for
the weight per foot of the weld.
