铜锌钎料Copper-zinc filler bls
使用说明 Operation Introduction
铜锌合金钎料主要用于气体火焰、高频、电阻、炉中等钎焊方法，钎焊铜、铜合金以及钢、铸铁、硬质合金等。
钎焊前必须严格清除钎焊处及钎料表面的油污、氧化物等污物，钎焊接头的最好间隙为0.025~0.1mm。钎焊时需要配合钎剂共同使用，方可获得良好的钎缝。铜锌半用氧——乙炔焰钎焊时，钎焊加热时间力求最短。并避免过热，以免钎料中锌的蒸发和接头处过分氧化而形成多孔钎缝。
|
The copper-zinc alloy filler bls are mainly adopted in the oxyfuel gas welding,high frequency welding,furnace welding,and used to braze the copper,copper alloy,steel,cast iron and hard alloy etc. Before brazing,you must b away all dirt very well on the brazed place and on the surface of b to be brazed such as greasy dirt,oxide and so on.Thebest brazed joins space is between 0.025mm to 0.1mm.In order to get good braze,you need make up the right flux in the process of welding. Theheat time should be shortest as possible and be avoided overheat so as not to the evaporation of zinc and the over-oxidation in the joint where will be bed the braze with many holes when these products are brazed in the oxyfuel gas welding.
