any ideas at all guys

well i graduated from doing t-joints to welding V-groove butt joints, both sides beveled at 45 degrees, Butted together. My instructor said i was doing **** good on the t-joints and it was time to do v-groove. Anyhow im having a problem with getting good penetration during the beginning of the root bead and at the end of the root bead it blows out. But the middle looks great. Any tips or suggestions on how to avoid these problems.

Are you giving your puddle time to penetrate without building up too much ? At the end, slow up and stop short of the end and just watch your puddle, its kind of hard to explain.

ok ill give it a try im doing the weld without using a backing strip so it is tricky any ides on how to to get a good root without a backing strip.

I'm having trouble getting a good root bead with out using a backing strip I'm using the small 7018 for the root and the 1/4inch for the rest of the beads in the v-groove.

i just cant seem to get the root in there right but the face of the weld looks pretty

Well i have got the root bead down pat now and my filler beads look pretty goot, but i am having trouble with the cover bead. Im finding it hard to get the weave bead tight enough, and im having trouble building it up as well. any ideas or hints for doing a weave bead.

Make sure your amperage is set high enough for the 1/4". Sounds like you may be going a little too fast, did you try slowing down some? Remember you are using a much larger rod compared to what you used for the root bead, especially if you went from a 3/32" to a 1/4"

ill try slowing down some that may be my problem. thanks for the suggestion and encourage others to comment on this topic as well.

Tyler, I think its wonderful that you want to be self employed. I'm a little concerned that you don't know what kind of welder you need. If you are not going to be doing the work your 'lead-man' should have the knowledge as to the equiptment. If you don't know what welders to set-up then your welding shop rep. will be able to help. 1" plate is no joke, I do hope you succeed. Best of luck. DZSNUTS
