Hi Plea for real experience information. Thicker Ali at above about 130A. Probably wire-feed-speed at or above 10m/min (394ipm) Thinking of marine-grade 5000-series Al-Mg, but experience of other grades would apply regarding this question. For welds, compare / contrast:
- spray-transfer/smooth-run ^ v
- Pulse-mode/stepped-progression
Or any comparison of spray/Pulse modes and of smooth/stepping progression.
Flaw and defect rates, please. This would be by radiography (x-ray) and mechanical test (strength alone will reveal everything important about Ali?).
Here in UK we have an orthodoxy about which process / approach must be used. Defect rates are / can-be high. Which surely simply cannot be the case universally??? Unfortunately I have not been able to test the welds I trust the most.
Thanks in advance, Rich Smith
