产品特性DESCRIPTION

SWE81B2产品为金红石型药芯焊丝，焊接过程为喷射过渡，具有焊接飞溅小，焊道平滑，熔覆效率高等特点。Mo的原子间结合力极强，所以在高温下仍有较好的强度，可以有效减少高温环境下的热变形并增加了焊道的耐腐蚀性。

The SWE81B2 product is a rutile-type flux-cored wire. It features spray transfer during welding, with characteristics such as low welding spatter, smooth weld beads, and high deposition efficiency. Molybdenum (Mo) has extremely strong interatomic bonding force, so it maintains good strength even at high temperatures, which can effectively reduce thermal deformation in high-temperature environments and enhance the corrosion resistance of weld beads.
