The fusing together of metals by melting the pieces where they meet and will be joined. Use of pressure and/or a filler material may aid in the fusion.
Weld bead
The metal that has been deposited in the weld joint, after it has cooled off.
Welded-wire fabric
Heavy wire laid in a grid pattern and welded to form a wire mesh mat. Available in sheets and rolls, used to reinforce concrete.
Welder
An individual who does welding work.
Welding
The fusing together of metals by melting the pieces where they meet and will be joined. Use of pressure and/or a filler material may aid in the fusion.
Welding clamp
Welding clamps help position the workpieces and lock them in place while the weld is being made.
Welding rod
Welding rods are used to melt two pieces of metal together to form a weld. Most steel welding rods can be run with an ac welder; specialty rods typically require an ac/dc welder.
Welding wire
Welding wire is used with mig welders. Solid wire requires a shielding gas to protect the weld; flux core wires can be run without gas.
Well
(1) A deep hole or shaft sunk into the earth to tap and remove an underground supply of water, gas, etc. (2) A shaft in a building or between buildings that is open to allow access for light and air.
Well casing
A steel or plastic pipe inserted into a drilled well to prevent dirt and debris from contaminating the water.
