聯(lián)系我時，請告知來自 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一樣。
符合GB SCu5180
相當(dāng)AWS ERCuSn-A
S212是含錫約5%、含磷不大于0.4%的磷青銅焊絲。塑性好，錫的加入，提高了焊縫金屬的耐磨性，焊接工藝性能良好。
S212 is a phosphor bronze welding wire with a tin content of about 5% and a phosphorus content of not more than 0.4%. Good plasticity, the addition of tin improves the wear resistance of the weld metal, and the welding process performance is good.
適用于紫銅、黃銅、磷青銅等及異種金屬的氬弧焊，鋼、鑄鐵的焊補(bǔ)和堆焊。
It is suitable for argon arc welding of red copper, brass, phosphor bronze, etc. and dissimilar metals, and repair and surfacing welding of steel and cast iron.

1. 工件焊接邊緣和焊絲表面的氧化物、油等污物在焊接前必須清除干凈，否則會引起氣孔、夾渣等缺陷，使焊縫性能降低。
2. 錫的加入擴(kuò)大了固、液相之間的溫度范圍，為了減少熱脆傾向，以小熔池、快速焊為宜。
3. 鎢極氣體保護(hù)焊時，工件要求預(yù)熱，僅用平焊位置施焊。
1. The oxides, oil and other dirt on the welding edge of the workpiece and the surface of the welding wire must be removed before welding, otherwise it will cause defects such as pores and slag inclusions and reduce the performance of the weld.
2. The addition of tin expands the temperature range between the solid and liquid phases. In order to reduce the tendency of hot embrittlement, a small molten pool and fast soldering are better.
3. During tungsten gas shielded welding, the workpiece requires preheating, and only the flat welding position is used for welding.
