摘要
压力容器产品制造过程中,产品的焊接工艺是否合理、先进将会直接关系到产品的质量。为确保产品的焊接质量,在正式焊接施工前必须进行焊接工艺评定。焊接工艺评定就是按照所拟定的焊接工艺,根据标准的规定,制作焊接试件,检验试样,测定焊接接头是否具有标准所规定的各种性能。双相不锈钢S31803采用(GTAW)焊接,目的就是,通过焊接工艺评定,获得焊接接头的力学性能及耐腐蚀性是否符合标准要求。为今后编制焊接工艺规程提供依据。
In the manufacturing process of the pressure vessel, the product rationality and advance of welding process will be directly related to the quality of the product. To ensure the quality of welding products, welding procedure evaluation must be made before welding construction. Welding procedure qualification istomake production welding test piece, test sample to determine whether the welded joints under various performance criteria in accordance with the welding process and standard requirementsDuplex stainless steel adoptssteel S31803 （GTAW） welding, the purpose is toget access to the mechanical properties of welded joints and corrosion resistance of the standard requirements through the welding procedure qualification andprovide the basis for the preparation of welding procedures in the future.
