Analysis and Prevention of Fracture Failures of Drilling Rigging Tools
Through the study of fracture failures of drilling rigs.Comprehensive research and anal-ysis were carried out in terms of fracture morphology,material composition,metallurgical organ-ization,mechanical properties,welding structure,crack extension mechanism and other aspects.By re-examining and optimizing the welding process and strictly controlling the material metallur-gy and forming process,the problem of drilling tool failures was solved.
