Описание
Характеристики:
LKT-90B3 with 2.5%Cr and 1%Mo, is designed for welding low-alloy steels with high tensile strength and creep-resistance steels such as SA387 Grade 22, A355 Grade P22 or similar materials.
Приложения:
It is suitable for welding of pipelines in pressure vessels and boilers with operating temperatures up to about 550°C
Примечания по использованию:
1. Use DC(-) current and 100%Argon gas at proper flow rate.
2. In order not to derogate the weld metal quality from particle. Be sure to clean up the contaminations on base metal and welding seam.
