In butt welding the strongest welds will have the fewest imperfections. Full penetration butt welds are made when they are in the within the parent(bigger, stronger) metal. Penetration while welding the metal is important to maintain and with thin pieces of metal this is possible however, with thick pieces edge preparation may have to be done to prepare the metal. Butt welding is accomplished by heating up two pieces of metal, or applying pressure, or doing both of those. This is because if they wanted to make something out of metal without welding it together they would have to bend everything and reinforce the structure which costs more than welding the two pieces together. In factories butt welding has shown how economical it can be for companies to use when building things out of metal.

A flange is something that either is internal or external that provided to strengthen a piece of material. It is used to attach two pieces of metal together such as pipe, framework in factories, and also flanges. Butt welding can also be done with brazing for copper pieces. Importantly, in a butt joint, the surfaces of the workpieces being joined are on the same plane and the weld metal remains within the planes of the surfaces.īutt welding is a commonly used technique in welding that can either be automated or done by hand on steel pieces. ( June 2018)īutt welding is when two pieces of metal are placed end-to-end without overlap and then welded along the joint (as opposed to lap joint weld, where one piece of metal is laid on top of the other, or plug welding, where one piece of metal is inserted into the other).
