Soldabilidad y Análisis del Comportamiento de la Soldadura por Fricción en Acrílicos.

Abstract

This project was developed by students of the Faculty of Mechanical Engineering at the National Polytechnic School, has as purpose, study and analyze the weldability of acrylic applying different methods, it consists of welding a series of test rods by analyzing the relationship and variability between the main process parameters such as: diameter, rotation speed, heating pressure, forging pressure, shrinking and welding time. Considering the relationships listed above and through the trial and error method, an optimization process was performed, identifying, reducing or eliminating the adverse factors that could cause the welded joints do not achieve the desired properties. Additionally, a comparative analysis was established between chemically binding acrylic by solvent which is the conventional method in the industry, and friction welding acrylic. All test rods obtained by the two processes were subjected to destructive and non-destructive testing, in order to find the process that provides the joints with better properties. The Nondestructive testing which were applied are: dye penetrant, visual analysis, macrography and transparency, the tensile test was the only corresponding to the destructive testing, the resistance value found by this test was be conclusive for this study, friction welding has better properties than acrylic bonding solvent.
