产品特性DESCRIPTION

SWE71T8-K6是一种低合金钢自保护药芯焊丝，不需保护气体。焊缝低温韧性优良，其熔敷效率高，电弧穿透力大，呈喷射状，操作容易，焊缝成形美观，脱渣容易。采用直流正接，适宜全位置焊接。由于熔渣凝固快，特别适合立向下焊。

SWE71T8-K6 is a low-alloy steel self-shielded flux-cored welding wire, using without external shielding gas. The weld has excellent toughness in low temperature, high deposition efficiency, large arc penetration and has spray-like shape, easy to operate, beautiful weld formation, and easy slag removal. Adopts to DC negative connection, suitable for all-position welding. Because the slag solidifies quickly, it is especially suitable for vertical downward welding.

应用APPLICATIONS

SWE71T8-K6特别适用于对低温韧性要求高的API X52至X65油管道的现场焊接。用于普通钢及高强度钢的现场焊接，如高层建筑、高炉等。SWE71T8-K6 is especially suitable for welding of API X52 to X65 oil pipelines with high requirements for toughness in low temperature. Used for on-site welding of ordinary steel and high-strength steel, such as high-rise buildings, blast furnaces, etc.
