S213 磷青铜焊丝-丹阳申澳焊接材料有限公司手机版

产品简介

铜及铜合金焊丝常用于焊接铜及铜合金，其中黄铜焊丝也广泛用于钎焊碳钢、铸铁及硬质合金刀具等。选用适当的焊丝进行氩弧焊是保证铜及青铜焊接质量的有效方法之一，不但可获得性能良好的焊缝而且有利于减少焊件变形。用氧-乙炔气焊时应配合铜气焊熔剂使用,或使用已包有铜气焊熔剂的铜焊丝。碳弧焊也是焊接铜及铜合金的常用方法之一，碳弧焊的焊接工艺和气焊类似，焊丝及熔剂也和气焊时一样。

详细介绍

标准：

符合GB SCu5210

相当AWS ERCuSn-A

说明：

S213是含锡约8%、含磷不大于0.4%的磷青铜焊丝。塑性好，锡的加入，提高了焊缝金属的耐磨性，焊接工艺性能良好。

S213 is a phosphor bronze welding wire with about 8% tin and no more than 0.4% phosphorous. Good plasticity, the addition of tin improves the wear resistance of the weld metal, and the welding process performance is good.

用途：

适用于紫铜、黄铜、磷青铜等及异种金属的氩弧焊，钢、铸铁的焊补和堆焊。

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.

注意事项：

1. 焊前必须清除工件焊接边缘及焊丝表面的氧化物、油污等污物，以免引起气孔，夹渣等缺陷，使焊缝性能降低。

2. 锡的加入扩大了固、液相之间的温度范围，为了减少热脆倾向，以小熔池、快速焊为宜。

3. 钨极气体保护焊时，工件要求预热，仅用平焊位置施焊。

1. Before welding, the oxides and oil stains on the welding edge of the workpiece and the surface of the welding wire must be removed to avoid defects such as pores and slag inclusions, which will 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.
