This can eliminate or reduce the oil flow. For leaks that cannot be pre-sealed, such as cracks, partial welding can be done until the leaks converge at a point, and then sealed with asbestos rope. For small leaks in thick plates, it is advisable to hammer them closed before welding. Micro-leaks are generally repaired using the rapid arc-pointing method, heating the area around the leak to promote expansion, suppress oil flow, and then welding in one go. To resist the decomposing force of residual oil flow, large arcs can be used for repairs, employing welding rods with a diameter of \u03c63.2 and below, with a current of 65-75A per millimeter diameter."}
