Welding Quality Control of Steel Structures in the Construction of Offshore Oil Fixed Platforms
As one of the most important facility for offshore oil and gas extraction,offshore oil fixed platforms have the characteristics of long service life,significant impact from marine environment and large welding volume of steel structures,which determine the importance of welding quality of platform steel structures.During the construction process of the platform,the welding quality of steel structure is affected by various factors such as base material,materials,personnel,equipment,process specification,environment,inspection of welding,which can easily lead to quality defects such as porosity,slag inclusion and undercut,reducing the safety performance of the platform structure.Therefore,this article summarizes the defects of the welding quality of steel structure during platform construction,analyzes causes in depth,and proposes targeted measures for welding quality control from three stages:before,during and after welding.
