Welding is a major part in the manufacturing of reservoirs where the raw material that is the metal sheet is rolled and welded and then domes are attached to the rolled sheet and the whole thing is welded. Manual welding causes adverse effects on the health of the workers. To overcome such disadvantages along with the precision and accuracy of the weld in mind, the welding process is automated by building CNC machine like mechanism along with a Y-axis roller. The portable CNC has 3 degrees of freedom i.e., X, Y and Z directions. Three motors are connected to the Arduino CNC shield and can be operated by using GRBL software. The Y axis roller turns according to the speed set by the operator depending on the diameters of the pressure vessel. The linear welding is first done on the rolled metal sheet which is first tack welded. And with the help of Y-axis roller circumferential welding is also done. The main advantage is that this automation decreases health effects, increases precision and accuracy of the welding, and increases productivity rate.
