It is recommended to use small diameter electrodes as much as possible for welding. The welding current must strictly adhere to the process requirements. The preferred welding method is the fast welding method. The heat from the arc should be utilized to heat the area around the leak.
The spot welding method should be applied with simultaneous cooling. For instance, after spot welding at several points, immediately cool the welding spots with cotton gauze dipped in water. At times, a combination of these methods may be necessary to effectively stop leaks. Welding leak stoppage requires versatility to guarantee its success.
Weld seam cracks mostly appear in the weld seam, showing a small hair shape. Some can be seen with the naked eye, while others need to be carefully identified or even enlarged to find. The main causes are reflow and slag inclusion caused by high soldering temperatures. 1.
The operation adopts the rapid welding method, using the heat of the arc to heat the surroundings of the leak point. After extinguishing the arc, quickly squeeze towards the leak with a hand hammer or sharp shovel, hammering the weld while welding. 2. Riveting Welding Method
a gas-tight seal with a seam welding machine involves making a series of overlapping spots. Each spot produced should be a fully formed nugget that is free of ex-pulsion. Using too little heat produces an undersized spot, which can cause a leak. Using too much heat produces expulsion, which can also cause a leak.
Prior to leak-sealing welding, it’s crucial to verify whether the pressure of the equipment to be welded could potentially cause personal injury. Furthermore, under the influence of the welding heat source, the equipment should have a safe pressure release passage, such as an installed safety valve. 2. Temperature control.

Treatment method for transformer oil leakage
When dealing with oil leakage in welding seams, first use a saw blade to clean the paint and oxide layer at the leakage area to expose its true color, then clean it with alcohol, seal the welding seam with sealant, and after solidification, the oil leakage can be blocked. If the leakage area is too smooth, it can be polished on the surface to increase adhesion. For those …
