产品特性DESCRIPTION

SWE80M产品为金属粉型高强钢药芯焊丝，具有熔渣薄、熔覆效率高、不易受潮、氢含量低等特点。本品使用Ar+20%CO2混合气体减少了硅、锰的烧损，可有效提升焊缝的抗拉和屈服强度及冲击性能。

The SWE80M product is a metal-powder type flux-cored wire for high-strength steel, featuring thin slag, high cladding efficiency, resistance to moisture absorption, and low hydrogen content. When using this product with an Ar + 20% CO₂ mixed gas, the burn loss of silicon and manganese is reduced, which can effectively improve the tensile strength, yield strength, and impact properties of the weld.

应用APPLICATIONS
