摘要：

Residual stresses in welded joints may have significant effects on structural performance, and residual stress measurement supports the understanding of weld joint behavior. This paper describes two methods for measurement of weld residual stress and presents detailed descriptions of their application. Examples include a comparison of residual stress in joints made by conventional electric arc and electron beam methods as well as residual stress mitigation by thermal stress relief and laser peening surface treatment.
