Abstract

UN PROCESO PARA PROPORCIONAR UNA MEJORA SIGNIFICATIVA EN EL DETRIMENTO DE LA CONDICION DE TENSION RESIDUAL DE TRACCION SOBRE EL FONDO DE LAS SOLDADURAS, ESPECIALMENTE SOBRE LA PARED INTERIOR DE LAS SOLDADURAS. EL METODO USA UN SOPLETE DE ALTA VELOCIDAD DE TRABAJO (>10 PULGADAS/MINUTO), ESPECIALMENTE EN EL ULTIMO O DOS ULTIMOS CORDONES DE SOLDADURA. EL PROCESO DEPENDE DE LA CAPACIDAD DE DISIPACION DE CALOR TERMAL LIMITADA DE LA PARED DE LA TUBERIA Y DE LA PROPIA JUNTA DE SOLDADURA CASI COMPLETA PARA GENERAR UN GRADIENTE DE TEMPARATURA SIGNIFICATIVO A TRAVES DEL MURO, Y POR TANTO UN GRADIENTE DE PRESION SUFICIENTE DURANTE LA SOLDADURA. ESTE GRADIENTE DE PRESION DA COMO RESULTADO PLASTICIDAD METALICA Y TENSION PERMANENTE, Y POR LO TANTO UNA REDUCCION EN LA MAGNITUD DE LA TENSION FINAL RESIDUAL O PREFERIBLEMENTE SI LAS CONDICIONES LO PERMITEN, UNA INVERSION EN LA DIRECCION DE LAS TENSIONES DE TRACTORAS A COMPRESIVAS. EL METODO PUEDE SER USADO COMO UN PROCESO DE SOLDADURA O UN TRATAMIENTO TERMICO. EN EL CASO DE TRATAMIENTO TERMICO, LA SUPERFICIE LEJANA DE LA JUNTA DE SOLDADURA SE CALIENTA SIN FUSION DEL MATERIAL QUE COMPONE LA SUPERFICIE ALEJADA.
