Explain how to make a flat butt joint.
What will be an ideal response?
To make a flat butt joint, place two clean pieces of metal flat on the table and tack weld both ends together. Tack welds may also be placed along the joint before welding begins. Point the torch so that the flame is distributed equally on both sheets. The flame is to be in the direction that the weld is to progress. If the sheets to be welded are of different sizes or thicknesses, the torch should be pointed so that both pieces melt at the same time. When both sheet edges have melted, add the filler rod.
