聯(lián)系我時(shí)，請(qǐng)告知來(lái)自 百分零部件網(wǎng)銅及銅合金焊絲常用于焊接銅及銅合金，其中黃銅焊絲也廣泛用于釬焊碳鋼、鑄鐵及硬質(zhì)合金刀具等。選用適當(dāng)?shù)暮附z進(jìn)行氬弧焊是保證銅及青銅焊接質(zhì)量的有效方法之一，不但可獲得性能良好的焊縫而且有利于減少焊件變形。用氧-乙炔氣焊時(shí)應(yīng)配合銅氣焊熔劑使用,或使用已包有銅氣焊熔劑的銅焊絲。碳弧焊也是焊接銅及銅合金的常用方法之一，碳弧焊的焊接工藝和氣焊類似，焊絲及熔劑也和氣焊時(shí)一樣。
符合GB SCu6800

S227是含少量鐵、硅、錳、鎳的錫黃銅焊絲，熔點(diǎn)約為880℃。熔融金屬流動(dòng)性好，由于含有硅，可有效地抑制鋅的蒸發(fā)。
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.
適用于銅、鋼、銅鎳合金、灰口鑄鐵的熔化極氣體保護(hù)電弧焊和惰性氣體保護(hù)電弧焊，以及鑲嵌硬質(zhì)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.

1. 焊前必須仔細(xì)清理焊件被焊部位及焊絲表面。
2. 焊前一般預(yù)熱至400~500℃后施焊，氧-乙炔火焰焊時(shí)必須配銅氣焊熔劑或銅釬焊熔劑使用。
3. 焊接火焰應(yīng)采用中性焰或輕微的氧化焰，適當(dāng)降低焊接時(shí)的溫度，提高焊接速度，盡量減少熔池在高溫下的停留時(shí)間，以減少鋅的蒸發(fā)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.
