in which an electric arc melts an electrode (welding wire, for instance) and partially melts the base metal. When the molten metals cool, the parts fuse together. There are different types of arc ...

Nevertheless, if your goal is to do work where the weld beads are featured as part of the ... is that the electrode is easily contaminated while being "scratched," and welding with a contaminated ...

Weld just enough to tack the parts together ... A flux-coated metal electrode that melts into the puddle and fills the bead is faster for welding thicker pieces. But stick welding is overkill ...

When it comes to making changes to or installing new parts ... an arc welding process performed by using an arc to heat two metals being joined, and a continuously fed filler (wire) electrode.
