Smaw vertical down penetration
By troilite Date If you are welding indoors, any process will work. Vertical up is more of a weave and a side-to-side motion with a lower amperage setting on the welder. Remember that voltage is proportional to distance. Choose the Right Electrode Size Large electrodes weld at high currents for high deposit rates. That lower bead is referred to as the shelf.
A quick reference for welding
Electrode coatings help optimize performance for various applications by influencing how quickly the slag freezes; penetration deep, medium, or mild ; and deposition rate. To get shallower penetration you do this in order of usefulness: I dont do much structural work anymore, so the uphill teqnique may be better on that application, I don't know for sure. Porosity and cracking are the most prevalent of these defects. Stick Welding Stick welding is the most common form of arc welding, but creating a good weld may not be easy for the beginner. I've got a good baseline setting for here at the house, now I just need to fine tune it to completely get rid of the splatter. The S can be sued in all positions, in particular it is ideally suited for vertical down welds upto 3,2 mm.
Stick Electrode And Welding Basics -
Undercut — A weld defect in which there is an overhang of the base material to the weld bead. Low Hydrogen — Refers to SMAW electrodes that provide weld deposits containing a low amount of hydrogen gas, typically 4 to 8 ml per g of weldment. Again, each puddle should be roughly 1. If you are welding with low-alloy steels and carbon steels with chemistry compositions above the "normal range", they will have a tendency to crack, particularly when welding on heavy plate and rigid structures. Increase voltage, Push torch, Decrease stickout.

You will realize that there is nothing comparable to SBI! In addition, steels with high sulphur and phosphorus contents are not recommended for production welding. Then change the electrode angle so the arc force holds the metal in the corners.
