Butt welding

[1] Factory fabrication demonstrates the cost-effectiveness of butt welding versus the more expensive overall processes of bending stock, reinforcing joints, and using fasteners where required.

[1] Butt welding is accomplished by heating up two pieces of metal, or applying pressure, or doing both[clarify] of those.

[1] Full penetration butt welds are made when they are in the within the parent(bigger, stronger) metal.

[1] Electrodes conduct current through the metal being welded in order join the two pieces.

For the heavily coated electrodes are commonly used in structural welding because they are much stronger and corrosion resistant.

[1] Flash butt welding is used with machinery and connects multiple pieces of metal together that are miss matched in size and shape.

[3] The joint also known as a square groove weld has many different forms in order to connect pieces of metal together and are all capable of bearing loads.
