Significance of welding process evaluation: Welding process is an important measure to ensure welding quality. It can confirm the correctness and rationality of welding process books compiled for various welded joints. Through the welding process evaluation, the use performance of the welded joint welded according to the proposed welding process book is checked to meet the design requirements, and a reliable basis is provided for the formal formulation of the welding process book or welding process card. Evaluation process: 1. Formulate preliminary welding process book2, welding specimens and preparation specimens 3, test specimens and specimens 4, determine whether the welded joint meets the performance required by the standard5, propose a welding process evaluation report to evaluate the proposed welding process book Scope of application of welding process evaluation: 1. Suitable for boilers, pressure vessels, pressure pipelines, bridges, ships, spacecraft, nuclear energy and bearing Heavy steel structures, etc. Manufacturing, installation, and maintenance of steel equipment. 2. Suitable for gas welding, electrode arc welding, tungsten argon arc welding, melting gas shielded welding, submerged arc welding, plasma arc welding, slag welding and other welding. Standard for Process Evaluation Domestic Standard 102NB/T47014-201102 “Evaluation of Welding Process for Pressure Equipment” 202G236-9802 “Field Equipment, Industrial Pipe Welding Engineering Construction and Pressure Pipeline Process Assessment” 3 “Steam Boiler Safety Technical Supervision Regulations (1996)” Note: Lifting industry process evaluation borrows this standard 402SY/T0452-2002 “Petroleum and gas pipeline welding process evaluation” (note: for petroleum, chemical process evaluation) 502G661-200102 “Steel structure welding specification” (note: highway and bridge process evaluation can be carried out with reference) 602SY/T4103-2006 “Steel pipe welding and acceptance” 7.JB4708-2000 “Steel pressure vessel welding process evaluation”.

Basic requirements for welding process evaluation: When pipe component manufacturing units or pipe installation units evaluate welding processes, they should meet the following basic requirements: 1. Welding pipe components meet the requirements of relevant standards. 2. The welding process evaluation specimens are operated by skilled licensed welders of the evaluation unit. 3. Welding tools and equipment must meet the relevant requirements, and the instruments used should be in normal working condition within the validity period of the calibration. 4. The operating procedures for the cutting, scraping, matching and refining of the specimens used shall comply with the relevant regulations. 5. The inspection and testing of welding process evaluation specimens shall be carried out by welders or relevant institutions. The testing agency must keep relevant inspection and test records, issue inspection or test reports, and be responsible for the inspection and test quality. 6. The evaluation unit prepares the welding process evaluation report according to the inspection and test report.
