Quiero agradecer y felicitar al Instructor por este video, he bajado todas sus presentaciones y/o explicaciones siéndonos de una guía muy completa y sólida, por otro lado me gustaría saber como puedo acceder a la parte de B de este curso, MUCHAS GRACIAS DESDE CHILE.
Ola consulta con este video o esta información se puede dar los exámenes finales de curso de particulas magneticas si alguien sabe esperando respuesta gracias
Hola buenas tardes. Pablo consulta. Como saber que tipo de isntrumento de particulas tengo que aplicar para realizar el ensayo. Vi que existen varios equipos yo solo conosco el yugo.
Buenos día compañero José Luis ante todo reciba un cordial saludo, quiera agradecer por tan excelente material audiovisual y a su vez quisiera saber si tiene disponible dentro de su biblioteca material disponible sobre un curso UT nivel II. Muchas gracias dejo mi mail por si puede ayudarme, feliz día
@@gonzaloiturrieta5169 2 gaus no creo. yo he trabajado un ducto y los caños tenían entre 4 y 10 gaus la mayoría y no teníamos problemas, pero había algunos que superaban los 20 gaus, mas no podía medir porque el instrumento solo medía hasta 20, y creo que ahí había algunos problemas, pero que tampoco fueron tan graves. igualmente sigo interesado en buscar información o literatura sobre el tema.

Una pregunta, en una pieza magnetizada a partir de cuantos gaus se afecta el arco de la soldadura?
Según mi experiencia como soldador, sobre los dos Gauss

Cómo puede tener tu correo ya que m interesa mucho tus cursos
Ya que cuando se realiza la reparación de una grieta en una pieza de acero m marca el contorno de soldadura y m están rechazando la pieza.
buenisimo
excelente
