Detailed introduction

气体保护焊用不镀铜焊丝

SOLID WELDING WIRE COPPER FREE ER70s-6

说明 DESCRIPTION

不镀铜焊丝是一种特殊的焊接材料，它没有传统焊丝上常见的铜覆层。这种焊丝在存储和使用时更易受到潮湿影响，需要更严格的保管条件，我司的纸箱覆膜与研发防锈油可以有效延长保存时间。

这种焊丝减少了环境和焊接工艺中铜的释放，有助于减轻对焊接设备的磨损，并降低工作环境中的铜尘风险。它在焊接过程中表现出较低的电阻率，可以提供更稳定的电弧和较少的飞溅，适用于高质量焊接要求的场合。由于其独特的属性，不镀铜焊丝特别适用于一些需要减少铜污染或特殊工艺要求的场合。

Non-copper-coated welding wire, lacking a traditional copper layer, is more susceptible to moisture and requires strict storage conditions, addressed by our film-coated cartons and anti-rust oil for longer preservation.

It reduces copper release and wear on equipment, offers a stable arc with less spatter, and is ideal for high-quality welding, especially in scenarios demanding reduced copper contamination.
