The root causes of welding residual stress of welded joints between metal region (including weld and heat affected zone) and the base metal due to the temperature Nonconforming strain degree difference generated, so any process to eliminate welding residual stress of welded joints are to make this region a non-coordinated deformation To change the direction of coordination, such as welded joints region plastically elongate or shorten the matrix plastically. Explosive treatment method is a typical By mechanical deformation method to eliminate welding residual stress type of technology. Not only could well eliminate welding residual stress by members of the explosion shock wave energy generated in the process, usually also In order to improve various mechanical properties of the material being processed. Explosive treatment method is suitable for a variety of engineering components to eliminate the stress of demand, especially suitable for large Medium-sized steel structure, as well as structural components made of dissimilar welded joints or stainless steel material. By staging the weld, multiple batches explosion treatment, To facilitate the solution to long and medium-sized structure of a total or partial weld stress relief treatment. Metallic materials welding residual stress Explosive approach Important Note. This standard does not point out all possible security issues. The user's responsibility to take appropriate safety and health practices and security Certified to comply with the conditions relevant state regulations.1 ScopeThis standard specifies the use of explosive welding residual stress treatment method to eliminate the principle of assessment to determine the processing parameters of the explosion, the explosion of the treatment effect Price, construction work and related security matters. This standard applies to a thickness greater than 5mm, the yield strength of not more than 900MPa, welding quality standards, good ductility (A > 10%) After welding of metallic materials welded components to eliminate residual stress treatment.2 Normative referencesThe following documents for the application of this document is essential.
