What color is a puddle?
A puddle is the colour of water. However, the ground underneath would change the colour of the puddle.
What change of state occur when a puddle disappears?
evaporating
Is a puddle of water evaporating endothermic or exothermic?
Evaporation is an endothermic process.
Functions of the welding flux?
The word FLUX means to clean. In the SMAW (stick welding) process it is the coating and does this by scrubbing the molten metal to remove impurities and floats them to the top and out of the puddle. It creates a slag to protect the puddle from contamination from the atmosphere while the weld cools. It slows the rate of cooling which tempers the weld. It adds alloys to the weld metal changing its characteristics such as hardness or malleability. It can also add metal to the puddle producing more weld per inch. It controls the amount of spatter produced. It determines what electrical current can be used. The thickness of the coating determines in what position ( flat, horizontal, vertical, overhead) the welds can be made. The thickness also insulates the electrode to help keep it from melting. Thicker coatings help direct the arc and keeps it from wandering. In the OFW (gas welding) process its main function is to clean.
What happens to a candle when it melts?
When a candle melts it gradually loses its shape, and turns into a puddle.
What is most common problem when mig welding in the field?
Wind! By disrupting the protective atmosphere around the puddle provided by the shielding gas.
What is remedy to prevent slag inclusions?
Remedies to prevent slag inclusions - Avoid atmospheric contamination using proper welding procedure e.g. adequate Shielding Gas Proper removal of slag from weld bead surface using wire brush Redesigning the weld joint to permit sufficient space for manipulation of the puddle of molten weld material
What is the welding for MIG welding?
mig welding is Metal Inert Gas welding. it typically uses Constant voltage DC+ current. It uses a wire feeder that supplies the electrode to the weld puddle and shields the molten weld puddle with inert gas (argon/co2 blend). Filler wire and shielding gas depend on the metal being welded.
Does metalcore welding wire need shielding gas?
Yes it does. Metal Core wire doesn't have flux in his core, but powder metal. The powder metal doesn't have addition of "gas producing elements" to protect the weld puddle from ambient atmosphere. Your wire supplier will help you in the selection of proper shielding gas. But never forget they are "sellers" before everything. Don't be foul.
What color is a puddle?

How many syllable in puddle?
There are 2 syllables in Puddle.
How long does it take for a puddle of water to evaporate?
That depends on how large the puddle is - how wide and how deep and how much water is in the puddle.
Who has the most solids a stream a pond or a puddle?
The puddle i know.
What is a mud puddle?
Its a puddle but its got mud or "soggy dirt" in it
When was Puddle Cruiser created?
Puddle Cruiser was created in 1996.

When was Andy Puddle born?
Andy Puddle was born in 1956.
