S226 低锡黄铜焊丝-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。

说明：

S226是含少量锡、硅的黄铜焊丝，熔点约为900℃，焊接工艺性能优良，焊缝成型良好。锡能提高焊丝的流动性、强度和抗腐蚀性，而硅可有效地抑制锌的蒸发、消除气孔和得到满意的机械性能。

S226 is a brass welding wire with a small amount of tin and silicon, with a melting point of about 900°C, excellent welding performance, and good weld formation. Tin can improve the fluidity, strength and corrosion resistance of the welding wire, while silicon can effectively inhibit the evaporation of zinc, eliminate pores and obtain satisfactory mechanical properties.

用途：

适用于氧-乙炔气焊黄铜和钎焊铜、钢、铜镍合金及灰口铸铁，也用于镶嵌硬质合金刀具等。

It is suitable for oxygen-acetylene gas welding of brass and brazing of copper, steel, copper-nickel alloy and gray cast iron. It is also used for inlaid carbide tools.

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.
