Soon after the long-term utilization of auto radiator, there may be break and damage, since the auto radiator is just not mounted tightly, or perhaps the you can find dangerous substances within the coolant which trigger corrosion, or it really is broken from the blade of the enthusiast. Typically, for your auto radiator with leakage, we can unload it form the car, come across the spot of leakage from the approach to injecting water or air and mark it for further fix.
Fix and Welding of Leakage in the Crack of Auto Radiator
1. Restore and Welding with the Crack in the Joint of H2o Tank & Outlet Pipe
The joint of lower drinking water tank and the outlet pipe is the spot where cracks happen most often. That's since the joint has gotten through long-term vibration. During the welding, we are able to clean the crack with wire brush and weld it with a welding iron.
2. Fix and Welding of Cracks in the Drinking water Tank
(one) Brazing
Before the brazing, the crack spot should be burnished with emery cloth or file to the original color with the metal. Light oxydizing flame must be applied during the welding so that the welding will be much firmer. Pay much more attention to the angle of the welding nozzle in case that it may well burn through.
part 2 Pasting
Before the welding, drill a Φ1.5 mm hole in the end in the crack. Then, uncover a copper or iron sheet together with the thickness of 0.8-1mm as pasting sheet. Clean the crack and the pasting sheet and apply zinc chloride solution on both of them. Press the pasting sheet against the crack closely. Heat the pasting sheet with welding iron so that they can closely fastened together. Weld the rest part in the edges.
Repair and Welding of Leakage in the Pipe of Auto Radiator
Leakage in the pipe of aluminum radiator is particularly tough, so we should certainly deal with it as per practical situation.
1. Direct Welding
Direct welding technique could be applied when the corrosion with the pipe isn't serious and you will find only some leakage holes. Before the welding, we really should het the radiating fins and seal them off with a welding torch, push aside the radiating fins with flat nose pliers and reveal the welding spot. Check the welding spots, clean them and apply fluxes on them. Weld the leakage holes with welding iron. Then rearrange the radiating fins.
2. Expanding the Pipe
During the welding, unload the upper and the lower drinking water tank. Expand the inner hole with the pipe with leakage for 0.3-0.4mm with special cleaning rod. Press the new pipe into the old one and weld the two ends. During the expanding in the pipe, make sure to remove the dirt and water scales inside the broken pipe, on the other hand, there will be a heat insulating layer between the new pipe and the old pipe which will affects the heat dissipation effect. Polish the outside in the new pipe. During the pressing, soap water is usually applied as lubricating solution. This technique will not break the radiating fins and maintain the outlook of auto radiator.
Auto radiator, which has gotten through repair and welding mentioned above, will need to be examined by sealing test to ensure there exists no a lot more leakage.
