How to solder diesel generator sink

Welded dieselgeneratorThe heat sink is usually soldered by tin. Wipe the oil of the diesel generator welding before welding, and then use the doctor blade to scrape out of the new metal layer, then appropriately heat, then heat it in the zinc oxide solution, then stick to solder. After sticking, the weld is packed, and the zinc oxide around the weld is washed with hot water to prevent corrosion.generatorOther parts of the group.
1, upper and lower water residential welding: On the upper water chamber, when the water chamber is not broken, it can be repaired directly, such as the long-term scavenging, welding. When the welding is applied, the steel skin is applied to a layer of solder first, put the steel skin in the water, and then heat it with the soldering iron to melt the solder, and weld it around it.
2, the solder repair of the heat sink: If the outer water pipe of the radiator is broken and the break is not large, the heat sink near the water pipe can be used to be a lot, and the solder is soldered directly. If the break is large or the medium water pipe is leaking, the method of tube, plugging, taking over, and changing pipe should be flexibly treated according to the specific body. However, the number of card tube and plug should not exceed 10% of the total total tube, so as not to affect the heat dissipation effect of the heat sink.
