Description
A decorative object whether it be a metal stairway, handrails, window frames, fences, furniture, entry gates, security doors, or hand tools can be classified as ornamental welding. Ornamental iron objects have closer tolerances, smoother finishes, and better fit-ups than most other welding. Students will learn how to fabricate a variety of ornamental projects using castings, bending radiuses and curves on pipe, tubing, and flat bar. Spot welding consists of applying pressure to two or more sheets of material by means of conducting electrodes and then passing a high current at low voltage through the sheets from one electrode to the other. This action combined with correct pressure causes fusion. Spot welding is done on primarily thin material and is a common welding process for auto body sections and other sheet metal assemblies. Students will learn how to safely sharpen drill bits.
