Abstract

Major pipelines across the world transport large quantities of crude oil, natural gas, and petroleum products. These pipelines play an important role in modern societies and are crucial in providing needed fuels for sustaining vital functions such as power generation, heating supply and transportation. If the pipeline carrying these chemicals burst/leaks it results in huge loss of life, money, time, and environmental disaster. To avoid this, proper joining of gas pipelines is needed and it can be done through welding process. Welding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics by causing coalescence. This is often done by melting the work pieces and adding a filler material to form a pool of molten material that cools to become a strong joint, with pressure sometimes used in conjunction with heat, or by itself, to produce the weld.
