Metal is transferred in liquid form across the arc in the axial spray metal transfer method of GMA welding.
convection
Yes. the other 2 methods by which heat is transferred is via convection and radiation.
The spray transfer method in welding can deposit approximately 5 to 15 pounds (about 2.3 to 6.8 kilograms) of filler metal per hour, depending on the specific equipment, material being welded, and technique used. This high deposition rate makes it suitable for applications requiring efficient welding of thicker materials. Factors such as travel speed, electrode diameter, and welding parameters can also influence the actual deposition rate.
Heat conduction is the method that represents the transfer of heat in a fluid. Heat is transferred from particle to particle through direct contact within the fluid.

Energy can be transferred through different methods such as conduction (direct contact between objects), convection (transfer through fluid movement), or radiation (transfer through electromagnetic waves). The type of material and the medium through which the energy is transferred will determine the most efficient method to use.
Both conduction and convection require an intervening medium, but convection requires the medium to be able to move.
No. Welding is a profession and a method of holding two pieces of metal together.
The heat transfer from one body to another is called conduction, convection, or radiation, depending on the method through which heat is transferred.
The method of heat transfer for a toaster cooking bread is primarily conduction. The heating elements in the toaster heat up, and the heat is directly transferred to the bread slices when they come in contact with the toaster's metal grates.
In welding technology a Pulsed MIG is a touchless transfer method concerning the electrode and the weld puddle, completed by forming one droplet of metal at the end of the electrode per pulse. Just the right quantity of current is added to drive that one droplet across the arc and into the puddle.
Radiation is the method of heat transfer that does not require a medium. Energy is transferred in the form of electromagnetic waves, such as light or infrared radiation, through empty space. This type of heat transfer can occur between objects that are not in direct contact with each other.
