Comment s\u00e9lectionner une classification ERTi AWS A5.16<\/h2>\n

La s\u00e9lection du m\u00e9tal d'apport doit suivre la conception technique et la sp\u00e9cification de mode op\u00e9ratoire de soudage qualifi\u00e9 (WPS), \u00e9tay\u00e9e par le proc\u00e8s-verbal de qualification de mode op\u00e9ratoire applicable (PQR). La correspondance avec la famille d'alliage nominale constitue un point de d\u00e9part, et non la r\u00e8gle compl\u00e8te d'acceptation.<\/p>\n\n\n\n\n\n\n\n\n\n\n

ERTi-2 est une classification de m\u00e9tal d'apport en titane commercialement pur couramment sp\u00e9cifi\u00e9e. Confirmez-la par rapport au mat\u00e9riau de base, au service, \u00e0 la conception du joint et au WPS\/PQR. Une valeur minimale de r\u00e9sistance \u00e0 la traction issue d'une sp\u00e9cification de produit de mat\u00e9riau de base ne doit pas \u00eatre pr\u00e9sent\u00e9e comme fondement de la classification AWS du m\u00e9tal d'apport.<\/p>\n

M\u00e9tal d'apport de soudage AWS A5.16 par rapport au fil g\u00e9n\u00e9ral ASTM B863<\/h2>\n

Deux sp\u00e9cifications diff\u00e9rentes sont souvent confondues dans les demandes. AWS A5.16\/A5.16M couvre les \u00e9lectrodes et baguettes de soudage en titane. ASTM B863 couvre le fil en titane et alliage de titane pour applications g\u00e9n\u00e9rales. Indiquez l'utilisation pr\u00e9vue et la sp\u00e9cification applicable, car un m\u00eame diam\u00e8tre nominal ne rend pas un fil g\u00e9n\u00e9ral acceptable comme m\u00e9tal d'apport de soudage.<\/p>\n\n\n\n\n\n\n
Ces deux \u00e9l\u00e9ments sont souvent confondus dans les demandes. Indiquez l'utilisation pr\u00e9vue et la sp\u00e9cification d\u00e9terminante, car le m\u00eame diam\u00e8tre nominal ne fait pas d'un fil courant un m\u00e9tal d'apport de soudage acceptable.<\/caption>\n

Quelle forme et quelles dimensions doivent figurer dans la demande de prix\u00a0?<\/h2>\n

Indiquez si le proc\u00e9d\u00e9 n\u00e9cessite des baguettes droites de longueur de coupe ou du fil sur bobine, puis fournissez la classification ERTi, le diam\u00e8tre, la longueur de coupe ou l'exigence de bobine, la quantit\u00e9, les exigences de surface et de propret\u00e9, l'emballage et le p\u00e9rim\u00e8tre documentaire. Beiyu confirme le diam\u00e8tre, la longueur, la configuration de bobine et le mode d'emballage propos\u00e9s pour la classification s\u00e9lectionn\u00e9e avant la lib\u00e9ration de la commande, plut\u00f4t que de consid\u00e9rer une plage fixe comme universelle.<\/p>\n

Quels contr\u00f4les de soudage affectent l'acceptation du titane\u00a0?<\/h2>\n

Le soudage du titane exige une pr\u00e9paration du joint, une manipulation du m\u00e9tal d'apport et une protection par gaz inerte conformes au WPS qualifi\u00e9. Maintenez le joint et le m\u00e9tal d'apport exempts de contamination, prot\u00e9gez la racine de soudure lorsque requis et maintenez la protection sur la soudure et la zone affect\u00e9e thermiquement pendant la dur\u00e9e indiqu\u00e9e par la proc\u00e9dure. Une coloration peut indiquer un probl\u00e8me de protection, mais la couleur de la soudure seule ne constitue pas un essai complet d'acceptation m\u00e9canique ou selon un code. Appliquez les crit\u00e8res d'acceptation du WPS applicable, du code de fabrication et de la sp\u00e9cification du projet.<\/p>\n

Contextes d'application courants<\/h2>\n

ERTi-2 est couramment envisag\u00e9 pour la fabrication en titane commercialement pur, notamment pour les joints de tubes, tube-\u00e0-plaque tubulaire et d'\u00e9quipements de proc\u00e9d\u00e9, lorsque la proc\u00e9dure qualifi\u00e9e s\u00e9lectionne cette classification. ERTi-5 est destin\u00e9 aux applications en alliage Ti-6Al-4V lorsque la conception et le WPS exigent un m\u00e9tal d'apport d'alliage correspondant. ERTi-7, ERTi-12 et ERTi-23 r\u00e9pondent \u00e0 leurs familles d'alliages et exigences de service respectives, sous r\u00e9serve de la qualification de l'ing\u00e9nierie et de la proc\u00e9dure.<\/p>\n\n\n\n\n\n\n\n

Fil de titane : poids par m\u00e8tre et m\u00e8tres par kilogramme<\/h2>\n

Le fil d'apport est achet\u00e9 au poids et consomm\u00e9 \u00e0 la longueur, le chiffre dont un ing\u00e9nieur en soudage a r\u00e9ellement besoin est donc le nombre de m\u00e8tres par kilogramme. Le tableau donne les deux sens sur toute la gamme de fils \u00e9tir\u00e9s, du fil fin de 0,1 mm aux diam\u00e8tres utilis\u00e9s pour les travaux TIG et MIG, en titane commercialement pur et en 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

Les deux colonnes proviennent de la m\u00eame section transversale : W (kg\/m) = π × d² × ρ ÷ 4000<\/strong>, et les m\u00e8tres par kilogramme en sont l'inverse. Les densit\u00e9s sont de 4,51 g\/cm³ pour le titane commercialement pur et de 4,43 g\/cm³ pour Ti-6Al-4V.<\/p>\n

L'utilisation pratique consiste \u00e0 estimer un travail plut\u00f4t qu'\u00e0 le chiffrer. Un cordon de soudure consomme une longueur de m\u00e9tal d'apport qui d\u00e9pend de la pr\u00e9paration du joint, de la technique et du taux de d\u00e9p\u00f4t plut\u00f4t que du seul diam\u00e8tre du fil, ces valeurs convertissent donc une estimation de longueur en poids d'achat, et non l'inverse. Les baguettes TIG en longueurs de coupe sont g\u00e9n\u00e9ralement fournies en longueurs de 1000 mm, ce qui rend le calcul direct : \u00e0 1,6 mm en titane commercialement pur, un kilogramme repr\u00e9sente environ 110 baguettes. Pour les petits diam\u00e8tres, les chiffres s'inversent, et un kilogramme de fil de 0,1 mm repr\u00e9sente environ 28 kilom\u00e8tres, raison pour laquelle le fil fin est achet\u00e9 au poids et planifi\u00e9 par bobine.<\/p>\n

Le fil en bobine comporte une variable suppl\u00e9mentaire. Le poids de la bobine est nominal, et la longueur utilisable sur une bobine partiellement utilis\u00e9e est inconnue sans la peser, les proc\u00e9d\u00e9s continus sont donc normalement planifi\u00e9s selon le nombre de bobines avec une marge plut\u00f4t que selon des m\u00e8tres calcul\u00e9s. Les diam\u00e8tres interm\u00e9diaires entre les lignes, ainsi que les nuances de m\u00e9tal d'apport au nickel et au zirconium, sont couverts par la calculateur de poids du titane<\/a>.<\/p>\n

D\u00e9tails des sp\u00e9cifications avec sources<\/h2>\n

Le document du m\u00e9tal d'apport porte lui-m\u00eame 2 d\u00e9signations qu'il vaut mieux citer exactement : l'\u00e9dition 2013 est publi\u00e9e sous AWS A5.16\/A5.16M:2013 (ISO 24034:2010 MOD), une adoption modifi\u00e9e de la norme internationale des m\u00e9taux d'apport, et l'ASME republie le m\u00eame texte dans la Section II Partie C sous SFA-5.16. Le renvoi SFA-5.16 d'un fabricant travaillant sous code et le renvoi AWS A5.16 d'un ing\u00e9nieur soudage aboutissent donc au m\u00eame jeu de classifications, et c'est pourquoi la demande de prix doit citer la d\u00e9signation et l'\u00e9dition contre lesquelles le descriptif de mode op\u00e9ratoire de soudage a \u00e9t\u00e9 qualifi\u00e9.<\/p>\n

La fiche d'usine de Beiyu associe ses grades de fil tr\u00e9fil\u00e9 \u00e0 7 classifications ERTi, ERTi-1, ERTi-2, ERTi-4, ERTi-5, ERTi-7, ERTi-9 et ERTi-12, chacune lib\u00e9r\u00e9e avec une composition chimique de coul\u00e9e v\u00e9rifi\u00e9e dans l'un des 2 laboratoires d\u00e9sign\u00e9s. Dans les demandes de prix de fil de soudage que Beiyu a examin\u00e9es au cours de 15 ann\u00e9es de travail d'exportation de titane, le champ le plus souvent absent est le grade du m\u00e9tal de base \u00e9crit \u00e0 c\u00f4t\u00e9 de la classe ERTi ; ajouter cette seule ligne permet \u00e0 Beiyu de recouper la classification avec le mat\u00e9riau de base avant l'offre plut\u00f4t qu'apr\u00e8s.<\/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\\\/fr\\\/author\\\/penn-ma\\\/\"}]}<\/script>\n<!-- \/ Yoast SEO plugin. -->","yoast_head_json":{"title":"Fil de soudage en titane | AWS A5.16

Il est venu \u00e0 l'approvisionnement en titane depuis l'autre c\u00f4t\u00e9 de la transaction. Avant de diriger les activit\u00e9s internationales de Beiyu, il a travaill\u00e9 chez Koch (Koch-Glitsch) et a particip\u00e9 directement \u00e0 la r\u00e9alisation d'un projet p\u00e9trochimique SABIC dans le Fujian, en Chine. Ce travail reposait sur des plans de contr\u00f4le et d'essais, la certification des mat\u00e9riaux et la tra\u00e7abilit\u00e9 par num\u00e9ro de coul\u00e9e, la coordination du contr\u00f4le par tierce partie, ainsi que le contr\u00f4le de la documentation et des dossiers de projet.
