ER4047 铝硅共晶合金焊丝
标准:
符合GB BAl88Si
相当AWS BAlSi-4
说明:
ER4047是铝硅共晶合金焊丝,焊接性能及焊缝特性相似于ER4043,但熔点低,流动性更好,能替代ER4043型焊丝来增加焊缝金属中的硅含量,降低热裂纹性,产生较高的熔敷金属剪切强度。本焊丝也可作为钎料使用。
ER4047 is an aluminum-silicon eutectic alloy welding wire. Its welding performance and seam characteristics are similar to ER4043, but it has a low melting point and better fluidity. It can replace ER4043 welding wire to increase the silicon content in the weld metal, reduce thermal cracking, and produce more High shear strength of deposited metal. The welding wire can also be used as a solder.
用途:
适用于铸铝、2000系列以及铝镁硅系列铝合金的焊接。
Suitable for welding of cast aluminum, 2000 series and aluminum-magnesium-silicon series aluminum alloys.

注意事项:
1. 焊前必须严格清除焊丝及工件表面的油脂、氧化物等污物。
2. 氧—乙炔气焊时须配铝气焊熔剂共同使用。
3. 焊后必须彻底清除残留的剂及残渣。
4. 作钎料使用时须配QJ201使用 。
1. The grease, oxide and other dirt on the welding wire and the surface of the workpiece must be strictly removed before welding.
2. During oxygen-acetylene gas welding, it must be used together with aluminum gas welding flux.
3. The residual agent and residue must be thoroughly removed after welding.
4. It must be equipped with QJ201 when used as a solder.
