2002年1月4日 · A welder has substituted an e7014 electrode for the specified e7018 (low hydrogen) electrode for welding new A36 steel to existing gr 30 (older) steel. AWS A5.1 shows that the E7014 and E7018 have similar strength properties but the E7014 has no charpy v notch limits, unlike the E7018. Also...

2005年4月4日 · E7014 has poorer radiographic soundness and toughness properties. If the structural design does not require volumetric NDE or toughness properties, E7014 can be used. If the design is in a seismic or low temperature application, E7018 should be used and will be required if design is per AISC.

2006年1月16日 · One of my welding buddies swears by 7014 rods. From what I've learned here, most folks carry 6010/11 and 7018.

Illusion, I'd stick with the proper rods for the current you're using. The AC and DC weld puddles have different characterisitcs as the DC has constant polarities of the work clamp and the electrode while AC is constantly switching polarity at the rate of 60 times per second in most areas of the U.S..

2018年3月21日 · On a side note, E6011 along with E6013 & E7014 were the go to rods. In 1985, E7018 AC wasn't big in the North American market as a manufactured rod. The first Invertors were starting to hit the market however.

2019年12月6日 · Hello folks, I just welded some AR500 to some A36 steel using 7014 rod. Reading a little more (something I should’ve done beforehand) I found that 7018 should’ve been used. This is an A36 hinge welded to an ar500 door so it’s nothing with a lot of stress. If I were to go back over the 7014 passes with some 7018, would

2013年11月6日 · E7014: Fleetweld 47 E6022: Fleetweld 22 Fill Freeze - Excessive moisture is indicated by a noisy or "digging" arc, high spatter, tight slag or undercut. Pre-dry unusually damp electrodes for 30 - 45 minutes at 200° - 230°F (90° - 110°C) before final drying to minimize cracking of the coating 300 to 350°F (150 to 180°C) 20 - 30 minutes

The slag system is viscous due to increasing high iron power content from the E6013 to E7014 and harder to puddle manage but they are all position rods just the same? So is the problem the rod or the operator? They also are the basis for slag in flux core wire development, with basic low hydrogen coatings so what is the real problem with them?

the only way i'm going to learn is by asking the stupid questions and appling what i've learned. but i asked the question because of the 3/32 e7014 i'm using i believeit was dave that said about certain rods working well with my welder thank you for your comment i didn't even think about that

However, if you think about coating type, droplet formation, arc length, and current limiting fume generation...you might get why you enjoyed that E7014 so much? Large electrode crucible, lower arc forces, smaller more plentiful droplets and a dense slag to clean pushing those slower melting elements away rather then burning them up into vapor ...
