The welding results are in. The welding quality is good. Key parameters: 3/4\" fillet weld, 4 passes DCEP, 22V, 100A, 15CM/MIN. Preheat: 300-350 DEG C for 2 hours, with slow heating. Post-heating treatment: 500 DEG C for at least 1 hour, with slow cooling using proper insulation. The electrode grade is currently unknown. Check it then.

The experimental results are poor; cracks appear after it has been running for some time

After replacing the welding rod, it has been operating at high temperatures for 100 hours with no problems. Let’s encourage ourselves a bit. :lol
