产品特性DESCRIPTION | |||||||||||||||||
SWE71T8-Ni是一种低合金自保护药芯焊丝，不需要保护气体。熔敷金属中含0.8%-1.10%Ni，具有优良的低温韧性，抗裂性能好。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，特备适合立向下焊。可用于焊接厚板及刚性大的重要结构。 SWE71T8-Ni is a low-alloy self-shielded flux-cored welding wire, which does not require shielding gas. The deposited metal contains 0.8%-1.10% Ni, which has excellent low temperature toughness and good crack resistance. Its deposition efficiency is high, the arc penetrating power is large and has spray-like shape. It is easy to operate, the weld seam is beautifully formed, and the slag removal is easy. Adopt DC negative connection, suitable for all-position welding. Because the slag solidifies fast, it is specially suitable for vertical downward welding. It can be used for welding thick plates and important structures with high rigidity. | |||||||||||||||||
应用APPLICATIONS | |||||||||||||||||
用于焊接要求韧性高和需要加镍的焊缝，特别适合于对低温韧性要求高的API X52至X70油气管道的现场焊接。也可用于普通钢、耐大气腐蚀钢及高强度的自动和半自动焊接，如输油输气管、海洋平台、贮罐等。 It is used for welding welds that require high toughness and nickel, and is especially suitable for on-site welding of API X52 to X70 oil and gas pipelines that require great low- temperature toughness. It can also be used for ordinary steel, atmospheric corrosion-resistant steel and high-strength automatic and semi-automatic welding, such as oil and gas pipelines, offshore platforms, storage tanks, etc. | |||||||||||||||||
