Study on the Analysis and Elimination Method of Welding Residual Stress for Mining Equipment
Mining equipment plays a key role in the mining and processing process,and the strength and life of its structural parts directly affect the safety and reliability of the equipment.Welding has been widely used in the manufacturing and maintenance process of mining equipment.However,residual stresses will inevitably occur in the welding process,and these residual stresses will have different effects on the fatigue strength,dimensional stability and stress corrosion performance of the equipment.This paper analyzes the welding residual stress of mining equipment in depth,and discusses the classification,causes,influence and control measures of welding residual stress,and puts forward the elimination method of welding residual stress to provide reliable guarantee for the welding quality of mining equipment.
