Scrap metal art only requires basic household tools, a welding machine, and an idea, rather than complex machinery or specialized tools. Here Mr. Balaji Vallal follows a pattern where the scrap metals are not cut or bent but welded together to make a shape out of it. This makes him stand out from other scrap metal sculptors. The time taken for completing a piece of art takes about a day’s time to sometimes weeks depending on its size and pattern used. Sizes range from 1.5 feet to 5 feet or even more. This type of craft is often used for interior decor of a home or office.
