产品特性DESCRIPTION

SW·ER90S-B3用于连接 Cr-Mo 和碳钢的不同组合。 它们设计用于使用 Ar1-5% O2 的 GMAW 或使用 100% Ar 的 GTAW。可以使用GMAW工艺的所有转移模式。由于强度较高，需严格控制预热、道间温度和后热，对于避免裂纹至关重要。

SW·ER90S-B3 is used for joining different combinations of Cr-Mo steels and carbon steels. They are designed for Gas Metal Arc Welding (GMAW) using an argon mixture with 1-5% oxygen (Ar1-5% O2) or Gas Tungsten Arc Welding (GTAW) using 100% argon (100% Ar). All transfer modes of the GMAW process can be applied. Due to their relatively high strength, strict control of preheating temperature, interpass temperature and post-heating temperature is essential to prevent cracking.

应用APPLICATIONS

适用于焊接工作温度在550℃一下的Cr2.5Mo的耐热钢，如锅炉管道、高温高压容器、石油精炼设备等的焊接。

It is suitable for welding Cr2.5Mo heat-resistant steel with a service temperature below 550℃, such as the welding of boiler pipes, high-temperature and high-pressure vessels, petroleum refining equipment, etc.
