Welding E7010/8010 versur E7018 - Eng-Tips
2007年1月2日 · RE: Welding E7010/8010 versur E7018 stanweld (Materials) 3 Jan 07 17:11 Due to its "fast freeze" characteristics, availability in smaller diameters and lower operating amperage range, the EXX10 electrode has a distinct advantage over EXX18 electrodes when welding steel sheet materials, whether coated or not.
E7016 & E7018 - AWS (welding) Code Issues - Eng-Tips
2011年2月23日 · The E7018 electrode contains iron powder in the flux whereas the E7016 does not. The iron powder increases the deposition rate and subsequently a higher amperage is used. With the root run a fast cooling electrode is desirable (that is why cellulosic electrodes are so commonly used)and the E7018 is not a fast cooling electrode. Regards, Kiwi
"E7018": a rant to designers. - Bridge engineering - Eng-Tips
2014年9月2日 · Almost every set of plans I see requires E70XX or E7018 electrodes. But just because your undergraduate steel design textbook used E70XX electrodes in the design example does not mean that is all there is to welding with 70-ksi electrodes. Designers seem to intend "E70XX" to generically mean "filler metal with a minimum tensile strength of 70 ksi".
E7018-1H4R Tests required as per ASME II Part.C SFA-5.1
2013年12月9日 · For our welding work on a project, we purchased the low hydrogen electrode E7018-1H4R Ø 3.2 mm. But the client rejected it because on the mill cer E7018-1H4R Tests required as per ASME II Part.C SFA-5.1 - Welding, Bonding & Fastener engineering - Eng-Tips
7018 not in rod oven - Welding, Bonding & Fastener engineering
2010年5月18日 · I don't know why it hasn't been mentioned yet; electrodes with an 'R' designator (E7018-H4R, E8018C3-H4R, etc.)for steels with yield strengths up to 50 ksi may be used with atmospheric exposure times of up to 9 hours. Cite:D1.5 2008(Bridges) 12.6.5.8 'For steels above 50 ksi, exposure is limited to the values of table 4.7'

Welding Electrode - Metal and Metallurgy engineering - Eng-Tips
2011年2月11日 · In regards to the welding electrodes, in order to save confusion at my site, I wanted to start ordering all E7018 electrodes with the "-1" designation to cover all circumstances where our temp requirements on carbon steel material may drop below -20F.(i.e. repair to prssure vessel shell rated to -50F) but still be able to use the remaining electodes on everday …
AWS A5.1 E7015 / 7018 - ASME (mechanical) Code Issues - Eng-Tips
2016年9月21日 · From what I can understand this is the first type of low hydrogen electrodes and now it was mostly replaced by E7018 that contains iron powder in the covering. We will ask them why did they choose E7015 instead of E7018, but I would like to know if we can force them to use the E7018 in the construction (qualifying the welders with that electrode)?
