    By the look of the film most of the hole are down the middle which would say mostly being in the root. IMO

    but like the guys say would have to see the pipe in hand to check it out better......

    do you have access to pratice and bending machine cause that will SHOW you the defects if in deed they are in the root.

      Go buy yourself a small thermostatically controlled rod oven and follow the instructions these guys gave you.

      No worries after that.

        Get a zipdisk and grind it out. Treat it like your looking for any other repair. Use fresh 6010....no oven.

          hey the oven is for the e7018 (lohi) no for the e6010 (5P or 5P+).

              I work in a code shop[asme] and ALL opened electrodes must be stored in a rod oven , period. Even stainless rods.It's not about porosity it's about moisture and hydrogen embrittlement.

                Showdog75 are you also required to keep 6010 in an oven?
                Or do you even use that rod, just Tig all your roots?
                Caution!

                  We don't use them but if we did they would be in the ovens. Because of this issue we Tig our joints all the way.On some big stuff in the header shop they Tig the first several passes then flux core.

                    6010 does not require, not should it have, heated storage.

                    Special Metals recommends all their rod (stainless, inconel, etc) be stored in an oven only 7 degrees above ambient temp.

                      E6010 should not be stored in a rod oven. It should be stored dry at room temps. The celluose based flux requires some moisture to work properly. Here's a link to proper storage of electrodes:

                        When you open a sealed box of rod you have a specific time limit to use the rod's or put them in the oven. If your shop is putting every rod in the oven (even stainless) that's your shop's policy(Probably to keep guy's or gal's from using cold rod's) Up here when it's -45c if you take a hot rod out of your oven it suck's in moisture. We combat this by using new rods out of a new box in the field, the rest of the non used rod's go back to the shop to be baked for shop use. Just because a shop does something does not make it gospel for everyone. Also if you put 6010 in an oven it will not work properly and the coating will burn off to fast. Hydrogen cracking only occurs if you put what ever you are welding into service right away if it sits for a week or so that is not an issue. Jef

                          I learned something today. We don't use 6010 so I guess thats why I didn't know.

                            It's not about cold rods , we use cold rods when a new can or box is opened. It's a moisture[hydrogen] issue. Rods can be out for a 8 hour shift then back in the oven.
