一种低合金高强度的气体保护焊丝
摘要：
本发明提供了一种低合金高强度的气体保护焊丝，其化学成分的重量百分数为：C：006-0.12％、Si：0.30-0.60％、Mn：1.40-2.00％、P≤0.025％、S≤0.015％、Cr：0.30-0.70％、Ni：1.0-1.6％、W：0.28-0.5％、Cu：0.25-0.50％、Re：0.05-0.15％，其余为Fe及不可避免的杂质。本发明焊丝得到的焊缝焊态及热处理后韧性良好，且成本低于现有同强度级别焊丝，性价比较高，具有很强的实用性。
摘要（英）：

The invention provides a gas-protection welding wire with low alloy and high strength, comprising the following chemical components in percentage by weight: 0.06%-0.12% of C, 0.30%-0.60% of Si, 1.40%-2.00% of Mn, not more than 0.025% of P, not more than 0.015% of S, 0.30%-0.70% of Cr, 1.0%-1.6% of Ni, 0.28%-0.5% of W, 0.25%-0.50% of Cu, 0.05%-0.15% of Re and the balance of Fe and inevitable impurities. The welding wire has the advantages of favorable welding state of the obtained welding line and thermal-treated toughness, lower cost than that of the traditional welding wire in the same strength level, higher cost performance and strong practicality.
