Make simplified studies and build small models in order to visualize the final composition of the proposed sculpture. Choose the kind of metal that will used in the design. Find flat sheet metal for raw materials, or collect unusual or visually appealing metal found objects to include in the sculpture (e.g., pipes, old farm implements, automobiles).
Prepare the metal to be welded by sanding or using steel wool to remove any rust or corrosion. Use an acetylene torch to cut the metal into interesting shapes for re-assembly by using a 225 to 300 amp arc welder. Attach the ground clamp as close as possible to the area to be welded. Use a 7024 "drag rod" for most welding. Grind beveled edges onto thick pieces of metal to be joined later by filling in the groove with a bead.
Hold the rod the correct distance from the metal to prevent it from sticking. Run beads smoothly and without interruption. Use a wide thick weave bead to join heavy pieces of metal. Move the rod from side to side in short strokes while running the bead. Weld with a thin stringer bead for lighter metal and detail work. Run the bead straight ahead along the joint in a tidy, even line.
Drag the rod in a controlled manner keeping a short arc. Experiment with different types of beads. Push the little puddles of molten metal into desired shapes. Use the welding rod like a paint brush. Develop an interesting looking bead, but make sure it holds the weld.
