When arc welding in the overhead position helps keep the molten metal from dropping out of the puddle?

If you throw some water up on the ceiling, surprisingly, a lot of it stays there. This is called surface tension. If you splash water in a pond small drops of water float on the surface. same thing. Plus, the molten puddle cools quite rapidly. Freezing the metal in place.

When performing overhead welding what additional safety equipment should be worn in order to protect the legs and feet from falling molten metal?
When welding one should always wear certain clothing. Leather boots (steel toe desirable), work pants (such as jeans) that cover the top of the boots, heavy cotton long sleeve shirt, welding beanie, gloves, and safety glasses. In most instances these items will protect you from sparks and weld spatter whether you are welding on a flat, vertical or overhead surface. A leather jacket can be worn to protect your shoulders and arms. Molten metal should not be falling if you are welding correctly. If you are sitting, while welding, a leather apron should be used.
What is arc crater?
Arc crater is the depression in the molten metal created by the end of the welding electrode during the welding of metal.
What part of a welding rod provides a gas shield to protect the molten metal?
The coating.
Why use a backing plate for butt welding?
To support the molten metal while it is cooling
Which welding method uses pool of molten metal?
For all intents and purposes , if you don't melt the base metal you are not welding. So I guess the answer is "all of them"
What is dual shield welding?
Welding process that uses both flux core, within the wire, and gas to protect the molten weld pool from contamination.
The cutting process results in oxides that mix with molten iron and produce?
Oxy-fuel welding and cutting process results in oxides that mix with the molten iron.
When forge welding is the metal molten?
No, it is just beyond red hot. Almost in a plastic state.
What type of welding which do not require a molten electrode?
TIG welding electrodes do not melt under most applications. Electrode means it carries electrical current. In MIG welding the wire becomes the electrode. In TIG and Gas Welding the filler material is called a rod. Stick welding uses rods called electrodes.
Is turning a penny gold a chemical or physical reaction?
Anything else then dropping it in molten gold is chemical
What do mean by flux and slag?
In (SMAW) Shielded Metal Arc Welding 'stick welding': Flux is the substance added to to molten metals to bond with impurities that can be readily removed. Slag is the waste material which is removed.
What are the similarities between soldering and welding?
In soldering and welding, 2 or more pieces of metal are joined by melting metal at the interface between them. When the molten metal cools and hardens, it physically bonds the pieces together.
