1, Shandong iron fence coldwelding data usage: first is to dispose of good appearance, do not to rust and oil, otherwise it will cause the glue off, coarse disposal is best, it can add the binding force between molecules, greatly enhance the service life of the repaired goods.
Remember to choose their own special welding materials of casting the corresponding data, such as cast iron will choose (Jin prime%) of JS902 iron cold welding materials, steel, aluminum, copper etc。 choose their special welding materials, has reached the best repairing effect。
2, hot welding and semi thermal welding, welding before welding parts to a certain temperature (above 400 degrees Celsius), the use of homogeneous electrode, select large current series repair welding, cold welding after welding。 The utility model has the advantages of good welding quality, low productivity, high cost and poor working conditions。
3, selection of non cold welding of cast iron welding rod, welding without preheating, welding current, welding with small slack, reduce welding stress. The strength and the color of the weld seam are different from those of the base metal. The processing function is poor, but the deformation after welding is small, the working condition is good, and the cost is low.
4, can also use high polymer materials welding, the repair only need to be repaired to clean clean appearance, direct manipulation technology.
We are filled with enthusiasm and passion towards work and customer, Shandong iron fence willing to with hard work and you create a better tomorrow!
