Step-by-step explanation:
It may be hard to think of a connection between offshore welding of oil pipelines and integrated circuit wafer handling. Thanks to Berkeley Process Control (www.berkeleyprocess.com) looking to leverage its technology skills, there fortunately is.
Teaming with J. Ray McDermott, an energy services company, the company developed an automated welding system for joining sections of pipe being laid underwater from barges. The objective was improved process control and productivity. The system's machine control and calibration technology uses lasers to detect the geometry of junctions between the beveled ends of 20- to 30-inch diameter pipe sections. Touch sensitivity, by detecting torque levels in robot positioning systems, allows precise location of six welding torches at each of five stations. Networked Berkeley motion-and-machine controllers provide real-time management of 14 servo axes on each station, the automatic weld-seam tracking system, and the automated welding process.
