S227 镍铁黄铜焊丝-丹阳申澳焊接材料有限公司手机版

产品简介

铜及铜合金焊丝常用于焊接铜及铜合金，其中黄铜焊丝也广泛用于钎焊碳钢、铸铁及硬质合金刀具等。选用适当的焊丝进行氩弧焊是保证铜及青铜焊接质量的有效方法之一，不但可获得性能良好的焊缝而且有利于减少焊件变形。用氧-乙炔气焊时应配合铜气焊熔剂使用,或使用已包有铜气焊熔剂的铜焊丝。碳弧焊也是焊接铜及铜合金的常用方法之一，碳弧焊的焊接工艺和气焊类似，焊丝及熔剂也和气焊时一样。

详细介绍

标准：

符合GB SCu6800

相当 AWS RBCuZn-B

说明：

S227是含少量铁、硅、锰、镍的锡黄铜焊丝，熔点约为880℃。熔融金属流动性好，由于含有硅，可有效地抑制锌的蒸发。

S227 is a tin brass welding wire with a small amount of iron, silicon, manganese, and nickel, and its melting point is about 880°C. Molten metal has good fluidity, and because it contains silicon, it can effectively inhibit the evaporation of zinc.

用途：

适用于铜、钢、铜镍合金、灰口铸铁的熔化极气体保护电弧焊和惰性气体保护电弧焊，以及镶嵌硬质合金刀具等。

It is suitable for molten electrode gas shielded arc welding and inert gas shielded arc welding of copper, steel, copper-nickel alloy and gray cast iron, as well as inlaid carbide tools, etc.

注意事项：

1. 焊前必须仔细清理焊件被焊部位及焊丝表面。

2. 焊前一般预热至400~500℃后施焊，氧-乙炔火焰焊时必须配铜气焊熔剂或铜钎焊熔剂使用。

3. 焊接火焰应采用中性焰或轻微的氧化焰，适当降低焊接时的温度，提高焊接速度，尽量减少熔池在高温下的停留时间，以减少锌的蒸发和氧化。

1. Before welding, the welded parts and the surface of the welding wire must be carefully cleaned.

2. Before welding, it is generally preheated to 400~500℃ before welding. Oxygen-acetylene flame welding must be used with copper gas welding flux or copper brazing flux.

3. The welding flame should be a neutral flame or a slight oxidizing flame. The temperature during welding should be appropriately reduced, the welding speed should be increased, and the residence time of the molten pool at high temperature should be minimized to reduce the evaporation and oxidation of zinc.
