*METAL WORKS SOLUTIONS* (1a) (i) Always wear appropriate personal protective equipment (PPE), such as safety goggles, gloves, and a dust mask, to protect against flying debris and inhalation of dust. (ii) Secure the workpiece firmly using a clamp or vise before drilling to prevent the material from moving and causing accidents. (1b) (i) Light scrap metal (ii) Heavy scrap (iii) Pig iron from blast furnaces (iv) Slag-forming agents (1c) (i) Used for fabricating structural frames and trusses due to its high strength-to-weight ratio and structural integrity. (ii) Employed in making staircases, railings, and piping systems, benefiting from its corrosion resistance and ease of fabrication. (1d) A hot set is a forging tool used during hot forging operations. It is essentially a chisel with a handle, designed to cut or shape hot metal while it is still malleable. The hot set is struck with a hammer to make incisions, grooves, or to cut through the heated workpiece. This operation is performed while the metal is above its recrystallization temperature, allowing it to be shaped or separated efficiently without cracking
