Abstract:
Most equipment in the Oil and Gas sector operates in harsh environments. Together with productivity needs that demand automation, special materials and high quality construction processes are required. Welding challenges in the case of large and complex equipment lie in positioning, tolerances and dissimilar thicknesses to be joined; regarding coating, issues are dilution and seam geometry. In order to address these problems a welding system able to determine the position of the torch along its oscillation and constantly adjust the welding parameters for consistent results, the Oscillation –Polarity Synchronized MIG/MAG Welding (MIG/MAG O-PS) was developed, as well as welding procedures for some specific applications.
Key Words: GMAW, Negative Electrode, Mechanization, Oil Rigs, Bridgebility, Torch Weaving, Reliability.
