铝及铝合金 5456铝焊丝 铝焊材ER5456

标准:

符合 GB SAI5456

相当AWS ER5456

说明:

ER5456是含少量锰及钛的铝镁合金焊丝，具有较好的耐蚀性及抗热裂性能，强度高。

ER5456 is an aluminum-magnesium alloy welding wire containing a small amount of manganese and titanium. It has good

corrosion resistance and thermal crack resistance, and high strength.

用途:

是铝镁合金氩弧焊及氧-乙炔焊的基本填充金属，在铝锌镁合金的焊接及铝镁铸件的补焊上也被采用。

It is the most basic filler metal for argon arc welding and oxygen-acetylene welding of aluminum-magnesium alloys. It is also

used in welding of aluminum-zinc-magnesium alloys and repair welding of aluminum-magnesium castings.

注意事项:

1.焊前应严格清除工件焊接边缘及焊丝表面的氧化膜和油污等污物。

2.施焊时可采用垫板托住熔化金属，以保证焊缝的成形。

3.氧-乙炔气焊时必须配铝气焊熔剂共同使用。

1. Strictly remove the oxide film and oil stains on the welding edge of the workpiece and the surface of the welding wire before

welding.

2. When welding, a backing plate can be used to hold the molten metal to ensure the formation of the weld.

3. Oxygen-acetylene gas welding must be used together with aluminum gas welding flux.
