Who do I need to talk to in central NC to get certified? I need to get it in SMAW and GMAW for carbon steel. I would hate to go and do this and have to use some rod I have never heard of. I am sure it is just 6011 6013 and 7018. Any info would be great.
 
Got my certifications from my college instructor. He's retired from teaching but I believe still test people. He could also maybe get you on a local person. His name is David Reames. I'll PM you his Number.
 
You should call Randy Porter at Mactec, they are a third part inspection company and can give you the certification for any welding you can think of. That is who we use all the time and they are accepted throughout the industry. And, they are located in Raleigh, so they are close to you
 
your WPS will prob. be MM1-b (at least from Mactec). Thats a bevel or fillet weld, carbon steel, using a 6010 root and 7018 cap using SMAW in thickness of .125 up to 1.240 inches thick in all positions.
 
the 6010 is very easy to weld with. it is similar to the 6011 but the slag is much cleaner than an 6011, its more similar to a 7018.
 
I can use the 6011 and 6013. Rather decent with them in vertical. I tried the 6010 last night at work. It gonna take some practicing. I finally found a rod harder to run than E316 Stainless rods
 
Normaly test procedures are fairly straight foreward and test only what is intended to be put in the joint. Stuctural test should be two beveled plates 3/8 gap with backing, this was for a distructive bend test. 6010 can be run contiuously in the arc for depositing metal or in a "Whip" method. I prefer the later as you can run alittle hotter and control the weld pool in all positions. The hardest part for people to get in a test sample is not having under cut or over weld, that saying you can put in a penetrated bead to begin with. Another common mistake is simply trying to fill the weld in with to few passes causing cold lap and poor fusion for several reasons.

But as for using another rod I'd say probably not.
 
cold lap and contaminants are the big problem with failed weld tests. Be sure to backgrind and clean properly before laying the cover pass. Do not undercut and take your time.


a 6010 harder to weld than a 316? I'd argue that, but every welder is different. I hate the 316/316L rods as they have a hard time holding up under verticle and overhead and tend to fall out and build up really bad "dogdicks". Move quick with those and weave, weave, weave...
 
I like a 7024 rod and would love to try and run some Inconel. Ran some 11018 on some tool steel in a Asphalt Silo once, ran just like a 7018. I'd drive down your way just to talk shop and meet up, you seem to have had a broad exposure to welding various alloys. Done much with more exotic tool steels requiring pre on post heat procedures with inner pass temperature specs?
 
Well, I've worked in lots of different industries requiring some various rods and processes. I have run some of the 11018 in the past on various things.

I've never really had to work with any tool steels like what your describing. About the hardest I've ever had to weld is some type of AR plate, something really, really hard above AR700, it had its own trade name and can't remember right now, but it was super hard and would crack within 20 seconds of finishing welding it if post heat wasn't applied and either wrapped in a fiberglass blanket or put in an oven and slowly cooled. Obviously pre-heating was required on it.

Inconel is an odd rod to weld as well. Its been a few years since welding with it, but its def. an odd one (and expensive)
 
Great info guys but way over my head with the last 2 posts. I have welded so much with the 316 rods Im starting to like them.
