El alambre de soldadura de titanio es un metal de aporte utilizado para unir titanio mediante soldadura por arco de tungsteno con gas (GTAW o TIG) y soldadura por arco met\u00e1lico con gas (GMAW o MIG). AWS A5.16\/A5.16M clasifica los electrodos y las varillas de titanio y aleaci\u00f3n de titanio principalmente por la composici\u00f3n qu\u00edmica del electrodo y tambi\u00e9n aborda requisitos generales, ensayos, embalaje y orientaci\u00f3n de aplicaci\u00f3n. Esta gu\u00eda explica las clasificaciones ERTi habituales, c\u00f3mo se relaciona la selecci\u00f3n del metal de aporte con el metal base y el procedimiento de soldadura cualificado, las formas de suministro que deben definirse en una solicitud de oferta y los controles del proceso que afectan a la aceptaci\u00f3n de la soldadura.<\/p>\n

Metal de aporte para soldadura AWS A5.16 frente a alambre general ASTM B863<\/h2>\n

Dos especificaciones diferentes se confunden con frecuencia en las consultas. AWS A5.16\/A5.16M abarca electrodos y varillas de soldadura de titanio. ASTM B863 abarca alambre de titanio y de aleaci\u00f3n de titanio para aplicaciones generales. Indique el uso previsto y la especificaci\u00f3n aplicable, ya que el mismo di\u00e1metro nominal no convierte un alambre general en un material de aporte de soldadura aceptado.<\/p>\n\n\n\n\n\n\n

\u00bfQu\u00e9 formato y dimensiones deben incluirse en la solicitud de oferta?<\/h2>\n

Indique si el proceso necesita varillas rectas cortadas o alambre en bobina y, a continuaci\u00f3n, proporcione la clasificaci\u00f3n ERTi, el di\u00e1metro, la longitud de corte o el requisito de bobina, la cantidad, los requisitos de superficie y limpieza, el embalaje y el alcance documental. Beiyu confirma el di\u00e1metro, la longitud, la configuraci\u00f3n de bobina y la modalidad de embalaje ofertados para la clasificaci\u00f3n seleccionada antes de la liberaci\u00f3n del pedido, en lugar de tratar un intervalo fijo como universal.<\/p>\n

\u00bfQu\u00e9 controles de soldadura afectan a la aceptaci\u00f3n del titanio?<\/h2>\n

La soldadura de titanio requiere una preparaci\u00f3n de junta, manipulaci\u00f3n del material de aporte y protecci\u00f3n con gas inerte que sigan el WPS cualificado. Mantenga la junta y el material de aporte libres de contaminaci\u00f3n, proteja la ra\u00edz de la soldadura cuando sea necesario y mantenga la protecci\u00f3n sobre la soldadura y la zona afectada por el calor durante el tiempo indicado por el procedimiento. La decoloraci\u00f3n puede indicar un problema de protecci\u00f3n, pero el color de la soldadura por s\u00ed solo no constituye una prueba completa de aceptaci\u00f3n mec\u00e1nica o seg\u00fan c\u00f3digo. Aplique los criterios de aceptaci\u00f3n del WPS aplicable, el c\u00f3digo de fabricaci\u00f3n y la especificaci\u00f3n del proyecto.<\/p>\n

Contextos de aplicaci\u00f3n comunes<\/h2>\n

ERTi-2 se considera habitualmente para la fabricaci\u00f3n de titanio comercialmente puro, como juntas de tubo, tubo a placa tubular y equipos de proceso, cuando el procedimiento cualificado selecciona esa clasificaci\u00f3n. ERTi-5 se utiliza para aplicaciones de aleaci\u00f3n Ti-6Al-4V cuando el dise\u00f1o y el WPS requieren material de aporte de aleaci\u00f3n compatible. ERTi-7, ERTi-12 y ERTi-23 se destinan a sus respectivas familias de aleaciones y requisitos de servicio, sujetos a la cualificaci\u00f3n de ingenier\u00eda y del procedimiento.<\/p>\n\n\n\n\n\n\n\n

Alambre de titanio: peso por metro y metros por kilogramo<\/h2>\n

El alambre de aportaci\u00f3n se compra por peso y se consume por longitud, por lo que la cifra que realmente necesita un ingeniero de soldadura son los metros por kilogramo. La tabla presenta ambas conversiones en todo el intervalo de trefilado, desde alambre fino de 0,1 mm hasta los di\u00e1metros utilizados en trabajos TIG y MIG, en material comercialmente puro y Ti-6Al-4V.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

Ambas columnas proceden de la misma secci\u00f3n transversal: W (kg\/m) = π × d² × ρ ÷ 4000<\/strong>, y los metros por kilogramo son su inverso. Las densidades son 4,51 g\/cm³ para titanio comercialmente puro y 4,43 g\/cm³ para Ti-6Al-4V.<\/p>\n

Su utilidad pr\u00e1ctica es estimar un trabajo, m\u00e1s que determinar su precio. Un cord\u00f3n de soldadura consume una longitud de material de aportaci\u00f3n que depende de la preparaci\u00f3n de la uni\u00f3n, la t\u00e9cnica y la tasa de deposici\u00f3n, no solo del di\u00e1metro del alambre, por lo que estas cifras convierten una estimaci\u00f3n de longitud en un peso de compra, y no al rev\u00e9s. Las varillas TIG cortadas a longitud suelen suministrarse en longitudes de 1000 mm, lo que simplifica el c\u00e1lculo: con 1,6 mm en titanio comercialmente puro, un kilogramo equivale aproximadamente a 110 varillas. En el extremo m\u00e1s fino, las cifras cambian de escala y un kilogramo de alambre de 0,1 mm alcanza unos 28 kil\u00f3metros, por lo que el alambre fino se compra por peso y se planifica por carrete.<\/p>\n

El alambre en carrete introduce otra variable. El peso del carrete es nominal y la longitud \u00fatil de un carrete parcialmente consumido se desconoce si no se pesa, por lo que los procesos continuos suelen planificarse por n\u00famero de carretes con un margen, en lugar de por metros calculados. Los di\u00e1metros entre las filas y las calidades de aportaci\u00f3n de n\u00edquel y circonio se incluyen en la calculadora de peso del titanio<\/a>.<\/p>\n

Detalles de especificaci\u00f3n con fuentes<\/h2>\n

The filler document itself carries 2 designations worth quoting exactly: the 2013 edition is published as AWS A5.16\/A5.16M:2013 (ISO 24034:2010 MOD), a modified adoption of the international filler standard, and ASME republishes the same text in Section II Part C as SFA-5.16. A code fabricator’s SFA-5.16 callout and a welding engineer’s AWS A5.16 callout therefore resolve to one classification set, which is why the RFQ should quote the designation and edition the WPS was qualified against.<\/p>\n

Beiyu’s factory sheet pairs its drawn wire grades with 7 ERTi classifications, ERTi-1, ERTi-2, ERTi-4, ERTi-5, ERTi-7, ERTi-9 and ERTi-12, each released with heat chemistry checked at one of 2 designated laboratories. In the welding-wire RFQs Beiyu has reviewed over 15 years of titanium export work, the field most often missing is the base-metal grade written next to the ERTi class; adding that one line lets Beiyu cross-check the classification against the base material before quotation instead of after.<\/p>\n

Over 15 years in titanium export he has learned to review each specification line himself, checking grade, standard, dimensions, tolerance and certificate scope against mill capability before quoting, rather than routing enquiries through a sales desk. He came to titanium supply from the other side of the transaction. Before leading Beiyu's international business he worked at Koch (Koch-Glitsch) and was directly involved in delivering a SABIC petrochemical project in Fujian, China. That work was built on inspection and test plans, material certification and heat traceability, third party inspection coordination, and project documentation and dossier control. Those are the same four things a process industry or regulated buyer will hold a titanium supplier to, and having had to enforce them as a customer is why they are treated here as part of the supply rather than as paperwork produced afterwards. His day-to-day work spans the questions this site is written to answer: choosing between commercially pure and alloyed titanium grades for a corrosive service, reading a mill test certificate against the ordered standard, and matching a buyer's designation (ASTM grade, UNS, German Werkstoff number or French NF code) to the same metal across markets. Beiyu supplies titanium, nickel-alloy and refractory mill products across bar, rod, plate, tube, block, ring, coil, ingot, forgings and machined parts, with EN 10204 3.1 documentation and heat-number traceability.\",\"url\":\"https:\\\/\\\/beiyutitanium.com\\\/es\\\/author\\\/penn-ma\\\/\"}]}<\/script>\n<!-- \/ Yoast SEO plugin. -->","yoast_head_json":{"title":"Alambre de soldadura de titanio |

Durante m\u00e1s de 15 a\u00f1os de exportaci\u00f3n de titanio, ha aprendido a revisar personalmente cada l\u00ednea de especificaci\u00f3n, comprobando calidad, norma, dimensiones, tolerancia y alcance del certificado frente a la capacidad de la f\u00e1brica antes de emitir una oferta, en lugar de canalizar las consultas a trav\u00e9s de un departamento comercial. Lleg\u00f3 al suministro de titanio desde el otro lado de la transacci\u00f3n. Antes de dirigir el negocio internacional de Beiyu, trabaj\u00f3 en Koch (Koch-Glitsch) y particip\u00f3 directamente en la entrega de un proyecto petroqu\u00edmico de SABIC en Fujian, China. Ese trabajo se basaba en planes de inspecci\u00f3n y ensayo, certificaci\u00f3n de materiales y trazabilidad por n\u00famero de colada, coordinaci\u00f3n de inspecci\u00f3n por tercera parte y control de la documentaci\u00f3n y los expedientes del proyecto. Esas son las mismas cuatro cosas que un comprador de la industria de procesos o regulada exigir\u00e1 a un proveedor de titanio, y haber tenido que aplicarlas como cliente es la raz\u00f3n por la que aqu\u00ed se tratan como parte del suministro y no como documentaci\u00f3n elaborada posteriormente. Su trabajo diario abarca las cuestiones que este sitio est\u00e1 concebido para responder: elegir entre calidades de titanio comercialmente puro y aleado para un servicio corrosivo, interpretar un certificado de materiales frente a la norma solicitada y relacionar la designaci\u00f3n de un comprador (calidad ASTM, UNS, n\u00famero Werkstoff alem\u00e1n o c\u00f3digo NF franc\u00e9s) con el mismo metal en distintos mercados.
