Abstract

Procedimiento y dispositivo de soldadura de las extremidades de dos elementos tubulares o similares, procedimiento según el cual los elementos a soldar entre sí son inmovilizados durante la operación de soldadura y el órgano de soldadura se desplaza alrededor de los elementos, el procedimiento caracterizado porque después de la puesta extremo con extremo de los elementos a ensamblar, se efectúa una primera pasada de soldadura sin aporte de metal; se provoca una depresión en el interior de los elementos así reunidos; y finalmente se realiza al menos una segunda pasada de soldadura manteniendo esta depresión.
