What Does Butt Weld Mean?
A butt weld is the simplest form of welding because it does not require cutting the material that needs to be welded into any particular shape. In this type of welding, two metals are joined by simply placing their ends together and then performing the welding operation. These two objects are nearly parallel and do not overlap.
A butt weld is also known as a butt joint.
Corrosionpedia Explains Butt Weld
Butt welding is a very basic, simple, reliable and economical form of joining two metal pieces. In this welding technique, no additional components or materials are required to make a joint between two metals. This process is quite suitable for prefabrication and producing special fittings. Afterward, the material is usually ground down to a smooth finish and either sent to the processing machine or sold as a completed product.
