If the runner has suffered from blade cracking, the missing blade part shall be welded first, see procedure no Map the extent of repair required (i.e. areas to be repair welded) for the blade and outlet area on the band, see Figure 1 above. For the blades special templates or alternatively thickness measurements shall be used. 3.

This is especially important for repair of the blades due to their relatively low stiffness. For the blade repair welding the welding shall hence be carried out alternately on the pressure and suction side. Moreover, peening of each layer shall be done. Start/stop pieces shall preferably be used at the blade outlet against the band to limit risk for weld defects at the outlet edge. 5.

Følgende typer tilsettmaterialer kan benyttes : - Artslike tilsettmaterialer (Dvs. tilsettmaterialer som gir et avsett med tilsvarende mikrostruktur og mekaniske egenskaper som grunnmaterialet) SMAW, FCAW, GMAW, GTAW and SAW are regarded as equal methods and can be used alternatively dependent on access etc. GTAW shall preferably be used for small weld repairs. The following types of consumables can be used : - Matching consumables (I.e. consumables giving a deposit with comparable microstructure and mechanical properties as the base material) - Austenittiske tilsettmaterialer - Austenitic consumables Hvilke type tilsettmateriale som skal benyttes avhenger av type løpehjul og skal være iht. interne retningslinjer (se Standard 31101) eller iht. krav i kontrakt. Which type of consumable to be used depend on the type of runner and shall be according to internal guide - lines (see Standard 31101) or according to contractual requirements. 4.3 Heftsveiser 4.3 Tack welds Heftsveiser (tosidige sveiser) kan inngå i den ferdige sveisen forutsatt at de er av samme størrelse som rotstrengen, sveist iht.

Dog tillates austenittiske rustfritt stål hvis belastningen tillater det. Både austenittiske- og artslike tilsettmaterialer tillates brukt. For sveiser som skal belastes før spenningsgløding, f.eks. løfteører, tillates derimot bare austenittiske tilsettmaterialer. Midlertidige påsveiste detaljer skal fjernes helt og sveiseområdet skal slipes rent og kontrolleres med 100 % PT. Akseptkriteriet skal være i henhold til CCH 70-3, klasse 3. Temporary attachments and lifting lugs shall be of the same type of material as that to which they are attached. However, austenitic stainless steel can be used if the loading is acceptable. Both austenitic- and matching consumables are allowed. However, for welds to be loaded prior to stress relieving, e.g. lifting lugs, only austenitic consumables are allowed.

Fugeflater rengjøres godt før sveising. Bunnstrengen skal legges fra den siden med vanskeligst tilkomst. For sveiser med full gjennomsveis (klasse I, II og III) skal rotfuring av bunnstreng med påfølgende sliping utføres. Sliping kan erstattes med blåserensing (ikke-metallisk type) ved vanskelig tilkomst. Området kontrolleres med 100 % PT før sveising fra motsatt side. For sveiser med delvis gjennomsveis (klasse IV og V) skal rotområdet sjekkes og rengjøres før sveising fra motsatt side. The root gap shall be 0-3 mm. Weld bevels shall be properly cleaned prior to welding. The root pass shall be welded from the side with most difficult access. For full penetration welds (class I, II and III), back gouging of root pass with subsequent grinding is required. Grinding can be substituted with blast cleaning (non-metallic abrasive) if difficult access. The area to be inspected by 100 % PT prior to welding from the opposite side For partial penetration welds (class IV and V) the root area shall be checked and cleaned prior to welding from opposite side.

Dersom det er praktisk skal det sveises vekselvis : - på skovler diametralt ovenfor hverandre - mot boss og ring - på skovlenes trykk- og sugeside Tennsår utenfor fugen er ikke tillatt og skal fjernes og kontrolleres som for midlertidige påsveiste detaljer. Etter sveising skal sveisen og området rundt rengjøres for all sprut, slagg, fluks og andre urenheter. The welding shall be organised in a way to minimise deformations. If possible, the welding shall be carried out alternately : - on blades diametrically opposite each other - against crown and band - on the blades pressure- and suction side Arc strikes outside the welding groove are not allowed and they shall be removed and inspected as for temporary attachments. After welding, the weld and the adjacent area shall be cleaned free from all spatters, slag, flux and other impurities. 4.7 Sveisereparasjoner 4.7 Weld repairs Før spenningsgløding skal det benyttes tilsettmateriale som angitt i WPS for produksjonssveising. Sår i skovlenes overflate oppstått før speningsgløding skal imidlertid alltid sveises med artslikt tilsettmateriale Sveisereparasjoner etter spenningsgløding skal forelegges prosjektet for godkjenning. Dog ved mindre overflate reparasjoner i sveiseavsettet der det opprinnelige tilsettsmaterialet er av austenittisk art, behøver man ikke godkjenning av prosjektet. Normalt kan mindre reparasjoner utføres med austenittiske tilsettmaterialer. Denne type reparasjoner skal fortrinnsvis utføres med GTAW for å redusere nødvendig opptak og sveisevolum. Ved større reparasjoner etter spenningsgløding skal ny spenningsgløding vurderes. Consumables as specified in WPS for fabrication welding shall be used prior to stress relieving. Any damages on blade surfaces occurred prior to stress relieving, shall in any case be welded with matching consumables Weld repairs after stress relieving shall be submitted to the project for approval. However if minor surface defects are detected in the weld area and the ordinary weld material is austenitic, is there no need for project approval. Normally, minor repairs can be carried out by austenitic consumables. GTAW shall preferably be used for this type of repairs in order to minimise the required excavation and volume of weld. For major repairs after stress relieving a new stress relieving shall be considered 5.0 NDT 5.0 NDT R:\Kjeller\Projects\Nathpa Jhakri.fra\Order\V12800\_Techdoc\Runner cracking\ doc

Notes for Table D: 1) Undercuts are not acceptable. 2) Depth x length. 3) Welding requirements as for acceptance class IV. 4) UT may be omitted or limited based on access and/or section thickness. Definisjoner og kommentarer til Tabell D: Definitions and comments to Table D: Akseptklasse I for UT Indikasjoner som overskrider 20 % av referansekurven skal undersøkes mht. form, indentitet og beliggenhet og evalueres iht. følgende akseptkriterier : Indikasjoner karakterisert som sprekker, bindefeil eller rotfeil er uakseptable uansett lengde. Andre indikasjoner som overskrider 60 % av referansekurven er uakseptable uansett lengde. Indikasjoner i denne gruppen med ekkohøyde som overskrider 40 % av referansekurven kan aksepteres hvis lengden er maks. 5 mm. Ved tvilstilfeller ved bedømmelse av UT skal akseptkriteriene for RT gjelde. Akseptklasse I for RT Akseptkriteriene skal være som følger : Lineære feil (lengde/bredde forhold større eller lik 3) er ikke akseptable. Runde feil (lengde/bredde forhold mindre enn 3) med hoveddimensjon større enn 1,0 mm er ikke akseptable. Konsentrasjoner av runde feil eller runde feil på linje med maks. størrelse mindere enn akseptkriteriet ovenfor er generelt ikke akseptable. Aksept kan gis etter egen vurdering. Acceptance class I for UT Indications exceeding 20 % of the reference curve shall be investigated with respect to shape, identity and location and evaluated according to the following acceptance criteria : Indications characterized as cracks, lack of fusion or incomplete penetration are unacceptable regardless of length. Other indications exceeding 60 % of the reference curve are unacceptable regardless of length. Indications within this group which produce a response exceeding 40 % of the reference curve can be accepted if the length is max. 5 mm. If any doubt in the interpretation of the UT response, the acceptance criteria for RT shall apply. Acceptance class I for RT The acceptance criteria shall be as follows: Linear defects (length/width - ratio greater or equal than 3) are not acceptable. Rounded defects (length/width - ratio less than 3) with a main dimension greater than 1,0 mm are not acceptable. Concentration of rounded defects or aligned rounded defects with a max. dimension less than the acceptance criteria above are generally not acceptable. Acceptance can be given after a separate assessment. R:\Kjeller\Projects\Nathpa Jhakri.fra\Order\V12800\_Techdoc\Runner cracking\ doc
