Resumen
El presente trabajo aborda una revisión de la literatura relacionada con el proceso de soldadura subacuática mojada la que se encaminó al estudio previo de los factores que de forma marcada intervienen en la calidad de la misma así como resaltar aquellos factores que marquen diferencia con la soldadura realizada al aire. Factores tecnológicos y metalúrgicos fueron discutidos, quedando demostrado que se necesitan consideraciones particulares para el estudio y evaluación de la soldadura
subacuatica. Fue demostrada la diferencia del comportamiento de este tipo de soldadura con la llamada al aire, de manera que se puedan obtener consideraciones que permitan la modelación con la ayuda de los elementos finitos, con la exactitud requerida en las estructuras obtenidas y la posibilidad de agrietamiento presente. Se propone además un procedimiento de medición de temperaturas como forma de validar los resultados obtenidos por la modelación.
The present work approaches a revision of the literature related with the process of underwater wet welding that headed to the previous study of the factors that intervene in the quality of the same one in a marked way as well as to stand out those factors that mark difference with the welding carried out to the air. Technological and metallurgists factors were discussed, being demonstrated that particular considerations are needed for the study and evaluation of the underwater welding. The difference of the behavior of this welding type was demonstrated with the call to the air; so that considerations can be obtained that allow the modelation with the help of the finite elements, with the accuracy required in the obtained structures and the possibility of present cracking. Also, intends a procedure of measuration of temperatures like form of validating the results obtained by the modelation.
