To explore the experimental methods for the evaluation of thermal correction processes in steel structures

in order to meet the requirements of the European steel structure specification EN1090-2 for the assessment of flame correction processes

and to fill the gap in the specific requirements for the evaluation of thermal correction processes in the current specifications. The factors affecting the performance of steel during thermal correction were analyzed

including the properties of the base metal

the heat source

the heating control

and the cooling control. Based on these influencing factors

an experimental method for the evaluation of thermal correction processes was proposed

including the heating method for the evaluation test plates

the recording of the test process

and the content of the inspection. Through the process evaluation experiments

key evaluation variables for thermal correction processes were identified

and these variables were divided into important factors and secondary factors. Tensile

impact

hardness tests

and micrographic metallographic tests were used as the content for evaluating the effects of thermal correction. The study concluded that it is recommended to formulate a thermal correction process evaluation plan according to the material

thickness

and specific conditions of the factory for steel structures

organize thermal correction process experiments and physical and chemical tests for the test plates

and compile a thermal correction process guide. In addition

train thermal correction operators with the corresponding skill level to ensure the effective implementation of thermal correction work requirements.
