In fact, the used gasoline in the 200-liter oil drums usually has 500-1000 grams. In the gasoline-filled fuel tank, it is also filled with a mixture of gasoline and air. If the oil is not clean, once the high temperature of the welding is ignited The oil and gas, there will be an explosion, resulting in
