First time ever attempting a 5g pipe welding, it is very challenging, you can see in the first half of the pipe, the inside root was really rough, the 2nd half of the pipe the root improved a bunch. It takes getting used to switching angle and direction of the electrode. Added a small amount of mig/ flux core at the end, we do a mig root then vertical up fillet welds. Last video i did the same thing, the bends for the 1 inch groove didnt go well, so i had to start it over.
