S201是含有少量硅、锰、磷等脱氧元素的特制紫铜焊丝。加入锡改善了熔融铜的流动性。具有焊接工艺性能优良、焊缝成型良好、机械性能高、抗裂性好等优点。
S201 is a special red copper welding wire containing a small amount of deoxidizing elements such as silicon, manganese, and phosphorus. The addition of tin improves the fluidity of molten copper. It has the advantages of excellent welding process performance, good weld formation, high mechanical properties, and good crack resistance.
用于紫铜氩弧焊及氧-乙炔气焊时作为填充材料。
Used as a filling material for argon arc welding of red copper and oxygen-acetylene gas welding.

1. 工件焊接边缘和焊丝表面的氧化物、油等污物在焊接前必须清除干净,否则会引起气孔、夹渣等缺陷,使焊缝性能降低。
2. 对接接头板厚小于3mm时,不开坡口;板厚为3~10mm时,开60°~70°V型坡口;板厚大于10mm时,开60°~70°X型坡口。为避免未焊透,一般不留钝边。
3. 焊前工件必须预热。板厚小于3mm预热温度为150~300℃;板厚大于3mm时,预热温度为350~500℃。
4. 进行TIG焊时用直流正极性焊接,以获得最大的熔透深度。
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. When the plate thickness of the butt joint is less than 3mm, no groove; when the plate thickness is 3~10mm, 60°~70°V groove; when the plate thickness is greater than 10mm, 60°~70°X groove . In order to avoid incomplete welding, generally no blunt edges are left.
3. The workpiece must be preheated before welding. The preheating temperature for plate thickness is less than 3mm is 150~300℃; when the plate thickness is greater than 3mm, the preheating temperature is 350~500℃.
4. When performing TIG welding, use DC positive polarity welding to obtain the maximum penetration depth.
