BLUME® ER80S-B2 (TIG) Datasheet

Q: What is BLUME® ER80S-B2 TIG Rod used for?
A: It’s designed for TIG welding of 1.25Cr–0.5Mo steels, commonly used in boilers, pressure vessels, and power plant piping operating at high temperatures.

Q: Can BLUME® ER80S-B2 be used for multi-pass welding?
A: Yes. It provides excellent interpass toughness and crack resistance, making it ideal for both single and multi-pass welding.

Q: What shielding gas is recommended?
A: Use 100% Argon for optimal arc control and metallurgical integrity.

Q: How does BLUME® perform under preheat and post-weld conditions?
A: Preheating to 300–350°F and post-weld stress relieving are recommended for maximum strength and hydrogen control.

Q: Why choose BLUME® over standard ER80S-B2 rods?
A: BLUME® rods are precision-engineered with superior chemical control, providing consistent heat performance, cleaner welds, and reduced post-weld maintenance — giving professionals a measurable edge in quality and efficiency.
