A: Yes, thermal input during welding can affect the local microstructural heat-affected zone. However, Alloy 800 is readily weldable using standard techniques (GTAW, GMAW, SMAW). Using matching or over-alloyed filler metals (such as Inconel 82 or 182) ensures the weld seam matches the base metal’s corrosion and heat resistance.<\/p>\n
