6" pipe welding

admin

all,im leanrning to weld in my own time, I did the 1 night a week course a few years ago and I suppose with my own practice Im at intermediate level nowim quite good at flat welding welding two pieces of steel togethernot too bad at uphill eitherthings im not so good at- when I hit a soft patch in the steel being able to keep a consistently good weld, im ****e in fact when this happens, I need some instructoin on what Im doing wrong hence Im wondering about a course? Im trying to well 4mm walled 6” pipe in a single pass I would be using 110-120amps DCEN (using a Kuhtreiber inverter with 6013 3.2mm electrode, electrode connected to negative)Wedling this pipe uphill and hiting a soft patch is a bitch, I can see the weld puddle digging into the steel and all of a sudden you have molten steel mixing with weld and slag, impossible to control what do the pros do to avoid this, I have tried speeding up and as soon as I hit a soft patch increase my travel speed with limited success, limited success being not blowing a hole in the pipeWhenever I hear that tell tale crackling sound of a hole not far from being burnt in the pipe I jump forward an inch without breaking the arc and continue on, when cooled down I go back and try again is this the right approach……..Tried turning the rod at an angle, the idea being larger surface area of rod burning with the same current meaning less heat. Tried turning down the amps, shortening the arc, it kinda works but then you hit good steel again and you say to yourself I need a bit more here…….. I must be doing something wrong…….Be nice to be able to weld light stuff 2-3mm steel together without making holes in it tooA couse I hope would get me to advanced level, give me some proper instruction on what im doing wrongAnywhere in Europe that does say an intensive course for 2weeks say on pipe welding? Burn a box of rods everyday would surely learn something espicallly with an instructor telling you what your doing wrong
