Conclusions
- Matching filler metals for Super 304H have been develope dand qualified.
- Welding with overmatching filler metal Thermanit 617 isapproved for DMV 310N, 347H FG and Super 304H, but care h as tobe taken regarding different thermal expansion coefficients .
- Creep rupture tests of weldments are completed or running.
Tests are running up to > 30.000h.
-
Int. Conference WELDS 2009, Fort Myers, Florida; June 24-26;, 2009
Ongoing investigations
welding of alloys 230, 263, 617mod. and 740
developing of matching filler metals for 310N
welding of dissimilar alloys
Most important issue:
testing the creep rupture properties of the mentionedfiller metals in long term tests
