Question

Quizplus · Accepted Answer

Slag is used in welding to protect the hot metal from being exposed to the atmosphere, which can cause oxides to form on the surface of the metal and weaken the weld. Slag also helps to slow down the cooling process, which can prevent cracking and improve the overall quality of the weld. Heat, oxides, and gas-forming agents are not used for this purpose.
