铸铁护栏用热焊好还是半热焊

  1、山东铸铁护栏冷焊资料的使用办法:首先要处置好被修外表,千万不能够有锈和油,否则就会造成胶层脱落,进行粗化处置是更佳,这样能够添加分子间的结合力,大大增强修补后的商品使用寿命。

  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.

  还要记住要挑选铸件自身资料相对应的专用冷焊资料,例如铸铁件就要选用(劲素成)JS902铁制冷焊资料,钢、铝、铜等也要挑选它们专用的冷焊资料,已达到更佳的修补作用。

  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、热焊及半热焊 焊前将焊件预热到一定温度(400℃以上),选用同质焊条,挑选大电流接连补焊,焊后缓冷。其特点是焊接质量好,生产率低,本钱高,劳动条件差。

  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、冷焊 选用非铸铁型焊条,焊前不预热,焊接时选用小电流、涣散焊,减小焊件应力。焊缝的强度、色彩与母材不一样,加工功能较差,但焊后变形小,劳动条件好,本钱低。

  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、也能够选用高分子资料冷焊,这种修补只需要把被修外表清理洁净就能够了,手艺直接操作。

  4, can also use high polymer materials welding, the repair only need to be repaired to clean clean appearance, direct manipulation technology.
