鋁及鋁合金焊絲廣泛用于鋁及其合金氬弧焊及氧-乙炔氣焊時作填充材料。氬弧焊是焊接鋁及鋁合金較完善的方法。氬弧焊可以不用熔劑，但氧-乙炔氣焊時必須配鋁氣焊熔劑共同使用。焊絲的選擇，主要根據母材的種類，對接頭的抗裂性能，機械性能及抗腐蝕性能等方面的要求綜合考慮。
符合GB SAI1070
相當AWS ER1100
S301是含鋁大于99.5%的純鋁焊絲。具有良好的可焊性和耐蝕性，以及優(yōu)良的塑性及韌性，但強度較低。
S301 is pure aluminum welding wire with aluminum content greater than 99.5%. It has good weldability and corrosion resistance, as well as excellent plasticity and toughness, but low strength.
氬弧焊及氧-乙炔氣焊焊接純鋁及對接頭性能要求不高的鋁合金作填充材料，廣泛應用于化學工業(yè)鋁制設備上。
Argon arc welding and oxygen-acetylene gas welding are used as filler materials for pure aluminum and aluminum alloys that do not require high joint performance. They are widely used in aluminum equipment in the chemical industry.

1. 焊前應嚴格清除工件焊接邊緣和焊絲表面的氧化膜和油污等污物，否則會使焊縫產生熔合不良并引起氣孔、夾渣等缺陷。
2. 為了保證焊透而又不導致塌陷，施焊時可采用墊板以托住熔化金屬。
3. 氧-乙炔氣焊時必須配鋁氣焊熔劑共同使用。
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, otherwise it will cause poor fusion of the weld and cause defects such as pores and slag inclusion.
2. In order to ensure penetration without causing collapse, a backing plate can be used to hold the molten metal during welding.
3. Oxygen-acetylene gas welding must be used together with aluminum gas welding flux.
