Background

• Welding is the most durable joint in pipe work

• When done correctly it never leaks, it is stronger than the pipe and has a lower tendency to corrode

• However pipe welding is a highly complex job depended on many parameters such as:
Joint surface must be beveled to enable filling of the gap with material
Job quality depends on welder’s skills and machine features
Temperature and humidity affect the final result
During stitching around the pipe the welder passes through all directions. These conditions demand constant change of welding currents
Even a “super welder” cannot control correctly a welding machine while stitching heavy pipes with a helmet covers his head and when working in an unfriendly environment

• In construction projects thousands of standard joints are fabricated in a certain amount of time and the last ‘non standard’ dozens take twice that time postponing delivery and causing very high expenses

• These jobs are carried out manually in very dangerous work conditions and it is very difficult to find qualified workers for such complicated tasks
