Abstract

Se divulga un método para soldadura por ojo de cerradura; el método ajusta de manera independiente energía en un rayo central enfocado y energía en un rayo anular enfocado concéntrico; en la terminación de una soldadura, la energía en el rayo central inicialmente se incrementa y después se disminuye, mientras que la energía en el rayo anular se disminuye; incrementar la energía en el rayo central permite una contracción controlada y prolongada del ojo de cerradura y pozo de material fundido, evitando grietas indeseadas.
