Welding consumables - Welding consumables for hard-facing
EN 14700 applies to welding consumables for hardfacing. The range of application includes surfaces of new structural components, semi-finished products as well as repair of surfaces of structural components which have to resist to mechanical, chemical, thermal or combined stress. This European Standard specifies requirements for classification of the consumables based on their chemical composition of the all weld metal of covered electrodes, cored wires, cored rods, cored strips, sintered strips, sintered rods and metal powders and on the chemical composition of solid wires, solid rods, solid strips and cast rods.

Diese Europäische Norm beschreibt die Anforderungen für die Einteilung der Schweißzusätze nach der chemischen Zusammensetzung des reinen Schweißguts der umhüllten Stabelektroden, der Fülldrähte, der Füllstäbe, der Füllbänder, der Sinterbänder, der Sinterstäbe und der Metallpulver sowie der chemischen Zusammensetzung für Massivdrähte, stäbe, bänder und Gussstäbe.
Produits consommables de soudage - Produits consommables pour le rechargement dur
La présente Norme européenne s’applique aux produits consommables de soudage pour rechargement dur. La gamme d’application inclut les surfaces des éléments de construction neufs, les produits semi-finis ainsi que la réparation des surfaces des éléments de construction ayant à résister à des sollicitations mécaniques, chimiques, thermiques ainsi qu’à des sollicitations combinées.
La présente Norme européenne spécifie les exigences relatives à la classification des produits consommables sur la base de la composition chimique du métal fondu hors dilution obtenu avec des électrodes enrobées, des fils fourrés, des baguettes fourrées, des feuillards fourrés, des feuillards frittés, des baguettes frittées et des poudres métalliques et sur la composition chimique des fils pleins, des baguettes pleines, des feuillards pleins et des baguettes moulées.
Dodajni materiali za varjenje - Dodajni materiali za trdo navarjanje
Standard EN 14700 velja za dodajne materiale za trdo navarjanje. Obseg uporabe vključuje površine novih strukturnih komponent, polizdelkov in popravila površin strukturnih komponent, ki morajo vzdržati mehanske, kemične, termične ali združene vplive. Ta evropski standard določa zahteve za razvrščanje dodajnih materialov, ki temeljijo na njihovi kemični sestavi čistega vara oplaščenih elektrod, polnjenih žic, polnjenih palic, polnjenih trakov, sintranih trakov in palic in sintranih kovinskih prahov ter na kemični sestavi masivnih žic, palice in trakov ter litih palic.
