I kinda forgot what happens when you use too much drag angle with 7018 or 6010 but can anyone remind me of what happens when you run too much drag angle with 7018 or 6010/11Miller Dialarc 250Miller Bobcat 225Hobart Oxy/FuelCouple of Dewalt and Milwaukee GrindersJET Bandsaw and Drill Press
Reply:No expert here but it can push the filler material to the back of the puddle. I'll leave it to someone with more expertise or Google to take this further.GravelThe difference between theory and practice is that in theory there is no difference.

Reply:Found it interesting that his preferred direction of travel changes when he uses 7018.I would have thought the visibility of the puddle would have been the over-riding parameter and don't know why that would change based on type of rod.

Reply:Sounds more like a term paper prompt if you really know your stuff....

Reply:Hello farmwelder, I'll go ahead and bite for you on this one. You are going to have preferred/recommended drag angles or even the use of a push angle in some instances for quite a few different electrodes. As to E7018, I would not "push" it unless there was no other way(access issues or something like that) to get the weld placed. As to effect of angle, more to the 90 degree position, wider, flatter weld deposit, as the drag angle decreases, narrower, higher bead deposits. I have performed welding on the ID of bushings where access and angle were very restrictive and have gone with drag angles that are more in the 10 to 15 degree area, still resulting in acceptable bead profiles and no discontinuities. E6010 will perform in a similar manner when you need to use it in that manner. However, when you tip any electrode to an angle where it is almost flat in relation to the weld surface you will generally experience a lot more spatter and possibly lose a certain degree of control over the bead profile, symmetry, and evenness. The biggest concern that I see for staying away from a really flat drag angle is to assist with bead control, symmetry, spatter, and possibly increased chances of arc-blow. As to push angles, slag entrapment would typically be the main reason for avoiding a push angle. Of the 2 electrodes that you included the E6010 would be the least susceptable rod for slag entrapment issues and the E7018 the most susceptible. So, there's my $.02 for the conversation.

Reply:I  occasionally push a 7018 weld in a tight overhead multi pass joint. Especially the top pas of a 3 pass weld. This helps reduce undercut when your not using a remote and the machine is too far away to make an amp adjustment. A push carries a bit less penetration than a drag. The key is being able to recognize when slag rolls out front of the weld puddle.JasonLincoln Idealarc 250 stick/tigThermal Dynamics Cutmaster 52Miller Bobcat 250Torchmate CNC tableThermal Arc Hefty 2Ironworkers Local 720
Reply:Jason, you brought up a point that I had forgotten about. As you said, when I am running a bead and I see issues of arc blow or the situation you spoke of in an overhead position, I will adjust my angle to a slight push. I generally do this as I am running a bead and either getting to the end of the weld joint or possibly the end of a rod, depending on how the arc is acting. Thank you for pointing that out. Best regards, Allanaevald
