Technology Development In Welding - Orbital Welding

  Doddi Abhinay Kumar,  Boddu Varshini,  Rao Harshita

Orbital welding machine is a tool used to weld rods or pipes circumferentially. Circumferential welding is always a difficult task to take on. Even the finest of the highly skilful workers also may end up with few welding defects often. Also it is difficult to weld rods of bigger dimensions. To overcome all these problems the best solution available is Orbital Welding Machine. In this welding a tungsten inert gas (TIG) electrode is rotated around the work pieces, which are held firmly. The electrode is rotated for 1800 or 3600 depending on the type of orbital welding equipment used. Though the Orbital Welding Machines are tailor made but still they offer a wide range of operation, i.e. for different diameters of the pipes and also for a wide range of materials. This flexibility will buy them a place in the industry in the view of mass production. Apart from this the other big reason for anyone to prefer Orbital Welding is its accuracy. The parameters which affect the welding like arc length, welding speed, etc. can be adjusted priorly with the help of the software. The motion of the electrode is guided by a predetermined programme. In this paper the working of the Orbital Welding Machine, its parts, advantages and disadvantages will be discussed.
