Assessment of impairment of the electrodes by increasing the number of pulses of the welding time on IF and HSLA steels galvanized and involvement of the mechanical properties in the nuggets welds
The objective of the following work is to analyze the deterioration of the quality of the welding buttons made in three different grades of galvanized conventional high resistance steels, caused by the wear of the copper electrodes, is the objective of the present study; which consists of performing 1000 welding points on two high resistance HSLA steels and one IF steel. 10 pairs of strip of 76.2 mm x 914 mm x two sheet thicknesses are used, in which 100 welding points are made. The characterization for evaluation was carried out in each twenty-fifth welding point until reaching 1000 points. The characterization consists of the measurement of indentation, penetration, hardness tests and stress tests.El objetivo del siguiente trabajo es analizar el deterioro de la calidad de los botones de soldadura realizado en tres diferentes grados de aceros de alta resistencia convencionales galvanizados, causado por el desgaste de los electrodos de cobre, es el objetivo del presente estudio; el cual consiste en realizar 1000 puntos de soldadura sobre dos aceros de alta resistencia HSLA y un acero IF. Se utilizan 10 pares de tira de 76.2 mm x 914 mm x dos espesores de l谩mina, en los cuales se realizan 100 puntos de soldadura. La caracterizaci贸n para evaluaci贸n se realiz贸 en cada veinticincoavo punto de soldadura hasta llegar a los 1000 puntos. La caracterizaci贸n consiste en la medici贸n de indentaci贸n, penetraci贸n, ensayos de dureza y ensayos de tensi贸n
