Welding - Post-weld heat treatment parameters for steels (ISO/TR 14745:2015)

ISO/TR 14745:2015 provides recommendations for post-weld heat treatment (PWHT) of steels with recommendations for holding temperatures and holding times for different materials and material thicknesses. These recommendations are limited to stress relieving for non-alloy steels (groups 1, 2, 3, 4, and 11) and to tempering for Cr-Mo-(Ni) steels (groups 5 and 6) and martensitic stainless steels (group 7.2), and are independent of type of product or location. The recommendations do not supersede any guidance given in material supplier specifications, e. g. thermo-mechanically treated fine-grain steels. It does not specify when PWHT is required. Such requirements are given in product standards, material specifications, or material data sheets.

Varjenje - Parametri toplotne obdelave po varjenju za jeklo (ISO/TR 14745:2015)

To tehnično poročilo vsebuje priporočila glede toplotne obdelave po varjenju za jeklo (PWHT) s priporočili za temperature in trajanje shranjevanja za različne materiale in debeline materialov. Ta priporočila so omejena na odpravo napetosti in so neodvisna od vrste ali lokacije izdelka. Priporočila ne nadomeščajo katerih koli smernic, podanih v specifikaciji materiala, ki jo je zagotovil proizvajalec, npr. termomehansko obdelana drobnozrnata jekla. To poročilo ne določa, kdaj je potrebna toplotna obdelava po varjenju. Te zahteve so navedene v standardih za izdelke, specifikacijah materiala ali listih s podatki o materialu.
