Abstract

In the preparation of this dissertation degree, to design and create an external pipe surface welding kit.Semi-automatic control due to human-made normal pipe welding Resulting weldingThis may not be as required by the external pipe surface welding kit controlled by the system.Semi-automatic. 4″ 500mm Black Round Tube Surface Welding Experiment Thickness 2 mm.

The design and construction of external pipe surface welding kits is controlled by a semi-automatic system. Use an electric monitor to control pipe rotation, with Inverter controlling the speed of the pipe rotation and using Servo Motor to control the linear slide.

Performance of welding integrity tests using different currents 5
The sizes are 40, 45, 50, 55 and 60 amps, and using DC current, the connection of the current can be seen.Size 50 amps It has a uniform welding line and melts together homogeneously and takes the distance in.There are 4 different welding distances: 2.5, 2.7, 2.9 and 3.1 mm. 2.5 mm. Has the most consistent and beautiful welding.
