What's so significant about welding something above you? (Unless I'm misunderstanding 'overhead welding'?)

- gluggymug 12y agoI've completed a certification in TIG, MIG and Stick welding and metal fabrication. Welding overhead is considered more difficult because gravity is making the molten metal run away from the joint. Less metal in the join means less strength. Too much metal means you have wasted welding rod AND possibly put more heat into the weld than needed which weakens it as well. For pipe welding if you can imagine a horizontal join of 2 round pipes, coming around the underside is where you will be doing an overhead weld.
