汽油容器在使用过程中,由于某些原因造成磨损、裂纹、撞伤等,导致产生渗漏,需要进行焊补修复。在焊补这类容器时,若稍不注意,就有发生爆炸的危险。从实践中我们摸索出充废气焊补法,先找准漏油点,把剩余汽油倒干净,然后发动另一辆汽车,用软胶管从消声器出口接出,将废气引入需焊补的油箱,数分钟后,用手试探油箱外壳, Petrol containers in use, due to some causes wear, cracks, bruises, resulting in leakage, the need for welding repair. In welding such containers, if not pay attention, there is the danger of explosion. In practice, we explored filling gas welding method, the first pinpoint the oil spill point, the remaining petrol poured clean, and then start another car with a soft rubber hose outlet from the muffler, the exhaust gas to be welded into the tank, A few minutes later, test the fuel tank shell by hand,
