best 7018 in this product range;

admin

can you tell me please are there any differences between 7018 sticks in that oerlikon site especially i want to learn about TENACITO electrode. is it different from others, seem like others are same but this is different from them. thanks for help. http://www.oerlikon.com.tr/pls/oerli...cted_submenu=0
Reply:Best for what?7018 or 7018-1 or 7018-H4 H8 MR1 come on dude do your part and know what it is you want to know?

Reply:I'll bite..If you're looking at Oerlikon, you are not in the US? Greece? Turkey? Other?Before any real response can be given, you need to let us know the application, and any requirements/standards that need to be met.For a backgrounder, all 7018 are low hydrogen deposit, and the "H8" and "H4" in the spec is the maximum expected hydrogen in the weld deposit, in ml/100g of weld metal. The difference between 7018 and 7018-1 is the temperature at which the Charpy impact energy is specified (notch toughness). The "-1" is specified at -50 degF, and regular 7018 is at -20degF. This is important in many low temperature applications, such as seagoing ships where the air temperature may be -50degF or lower.As a general rule, unless there is a reason, regular 7018 is ok (diffusable hydrogen will be 16ml/100g or less if not specified) for most applications, and most manufacturers have H8 or H4 as the spec for all of their electrodes. In terms of usability, I have limited experience with Oerlikon (it comes back from jobs on occasion) so can't comment specifically. 7018's all weld pretty similarly, though some types have easier slag removal, some tend to leave porosity at starts (especially if not properly stored), and you have the same issue as with all electrode types that some just don't run smoothly. Storage: Once the sealed container is opened, they MUST be stored in an oven at roughly 250degF (225degC) to keep them dry and maintain the specified hydrogen level and good operating characteristics. The flux will absorb moisture from the air. If the containers are not sealed (some manufacturers ship the rods unsealed, and they need to be baked at a higher temperature before use), contact the manufacturer for specific information.See: http://www.lincolnelectric.com/knowl...llermetals.asp
Reply:yea a bit vague on the OP question.I have used that rod when i lived  in Scotland and liked it.it was in use for oil rig construction for the north sea (cold)used to run better than some of the Lincoln that i get now over here in the US.and we ran them on lincoln welders.What did you want to know about them?if you are more specific, then we will beG
