Aplicación de la norma AWS C2.16/C2.16M:2002 para la calificación de operadores de termorociado: HVOF, arco eléctrico y flame spray, en la empresa Imetca

Abstract

The main objective of this project is to qualify the IMETCA´s workers as operators of arc spray, HVOF and flame spray following the procedure dictated by AWS C2.16 / C2.16M:2002, by obtaining test pieces and performing tests for qualitative and quantitative evaluation of properties such as texture quality, finishing, bond strength, adhesion, hardness, percentage of pores and oxides, etc., and evaluate the correct combination of variables such as surface preparation, equipment configuration and spray parameters. Compare them with the acceptance criteria of the standard to determine if the applicants are suitable for the application of process in such a way as to guarantee that the coating will fulfill the purpose for which it was applied. As a result of the evaluation of knowledge and skills through tests performed on the sprayed specimens of each operator, it was concluded that the operators Alexis Chulde, Jefferson Montesuma and Diego Cadena approved the qualification of operators of arc spraying metal alloys for engineering purposes.
