1. For circumferential butt joint welds made from one side into backup bars or similar one-side welding, radiographs may show dark lines intermittently on a radiograph at the root of the joint. This is normal and is not cause for rejection, provided the welds are otherwise considered acceptable. For one-sided welds, some non-fusion or lack of penetration less than 10 times the column wall thickness in length and rounded indications shall not be cause for rejection, provided the governing stress is compression.

2. Longitudinal butt joint welds shall be visually inspected on the total outside length and for a distance of one diameter on the inside of each section welded. Areas less than ten times the column wall thickness in length, with lack of penetration not exceeding 1/32 in. deep, are acceptable. For exterior butt joint welds with base metals of 3/8 in. or less full penetration is required. For base metals of thickness greater than 3/8 in, welds shall be either full penetration or partial penetration unless otherwise specified. In addition, complete joint penetration welds shall be provided for a distance of at least 3 in on each side of intersecting joints. A maximum undercut of 1/32 in is permitted, provided that the unwelded portion plus the undercut shall not reduce the thickness of the joint by

5.0 PRÉPARATIONDE LA SURFACE

Tout appareil nécessitant un étalonnage selon les exigences de la norme de référence, dewa l'être d'après les exigences de celle-ci et une preuve d'étalorurage sera maintenue au dossier de l'instrument.

Cette procédure d'examen sera revue sur une base annuelle par le superviseur d'examen principal en soudage et révisée au besoin afin de confirmer sa conformité aux norrnes de référence. Cette revue sera docnmentée sur le formulaire Labcan F980.

La qualification sera reconduite conditionnellement à ce que la vérification annuelle du CWB confirme que les exigences de la nonne sont rencontrées.

Généralement de bons résultats sont obtenus sur une surface soudée, coulée, roulée ou forgée.

Un examen visuel doit être réalisé avant I'examen par particules magnétiques et les discontinuités de surface doivent être réparées avant ce dernier.

Les surfaces à examiner ainsi que la région adjacente (au moins 2.5 cm de chaque côté) seront sèches, propres, et libres de corys gras, de sable, de calamine, de laitier et de rouille non-adhérée. Un dressage des surfaces par meulage ou par usinage peut s'avérer nécessaire lorsque des irrégularités de surface peuvent masquer des indications de discontinuités inacceptables.

All instruments needing calibration in accordance with referencing code shall be calibrated as per code requirements and proof of such calibration shall be kept on record.

This examination procedure will be reviewed on a yearly basis and revised when necessary by the main examination supervisor as to confirm its compliance to the referencing code. This annual review will be documented on Labcan's form F980.

Certification shall continue in effect subject to annual verification from the CWB that the requirements of this Standard are being met.

SURFACE PREPARATION

Satisfactory results are usually obtained when the surfaces are in the as welded, as rolled, as cast, or as forged conditions.

A visual examination shall be conducted prior to the magnetic particles examination and rejectable surface discontinuities shall be repaired before the later is carried out.

Surfaces to be examined and adjacent areas (at least one inch on either side) shall be dry, clean and free of oil, grease, sand, loose rust, scale or flux. Surface conditioning by grinding or machining may be necessary when irregularities would otherwise mask the indication of unacceptable discontinuities.

Le nettoyage peut être effectué en utilisant des détergents, des solvants organiques, des acides, des décapants à peinture, un dégraissage à la vapeur, un nettoyage au jet de sable ou avec des billes d'acier ou le nettoyage aux ultrasons.

Lors de travaux selon la nonne ASME, si I'examen doit être réalisée sur une couche de peinture non magnétique ou sur une pellicule contrastante, il doit être démontré que les indices peuvent être détectés au travers de la couche maximale connue.

Lorsqu'une qualihcation de procédure est spécifiée, tout changement dans les paramètres identifiés comme étant des variables essentielles au tableau T-721 de la norme ASME sect. V requièrent une requalification de la procédure d'examen par démonstration.

Les particules magnétiques doivent avoir une grande perméabilité ahn de permettre une facilité de magnétisation et d'attraction à la zone de la perte du flux et également avoir une basse rémanence afin d'éviter I'attraction (agglomération de particules) entre elles. Le contrôle des formes et dimensions des particules est requis afin d'obtenir des résultats constants.

Le choix de la couleur pour toutes méthodes est basé dans le but d'obtenir le meilleur contraste possible à la surface d'examen.

Cleaning may be accomplished using detergents, organic solvents, descaling solutions, paint removers, vapour degreasing, sand or grit blasting or ultrasonic cleaning methods.

For ASME related work, if non magnetic coatings are left on the part or paint is used as surface enhancement contrast in the area being examined, it must be demonstrated that the indications can be detected through the existing maximum known coating thickness.

When procedure qualification is specified, a change of a requirement in table T-721 of ASME Section V, identified as an essential variable, shall require requalification of the written procedure by demonstration.

The magnetic particles must have high permeability to allow ease of magnetizing and attraction to the site of the flux leakage and low retentivity so they will not be attracted (magnetic agglomeration) to each other. Control of particle size and shape is required to obtain consistent results.

The color chosen for any given examination should be one that best contrasts with the test surface.

Seulement les produits Magnaflux ont été démontrés. L'utilisation d'une autre famille de produits est interdite à moins d'être préalablement démontré auprès de I'inspecteur autorisé.

Les particules sèches consistent en un mélange de sphères et d'aiguilles allongées qui leurs permettent une bonne mobilité et sensibilité Les examens par magnétoscopie ne seront pas effectués sur des pièces dont la température de surface excède 260"C pour les particules jaunes, 315"C pour les particules noires et rouges et 400'C avec la poudre grise.

Les particules humides seront en suspension dans un liquide approprié et elles seront agitées d'une façon mécanique ou autre pour les maintenir en suspension. La concentration des particules sera mesurée au début de chaque période d'inspection en utilisant un tube de sédimentation de 100 ml. La concentration des particules humides visibles sera maintenue entre 1.2 et 2.4

ml. La concentration des particules humides fluorescentes sera maintenue entre 0.1 et 0.4 ml par 100 ml de suspension.

L'examen avec particules humides visible et fluorescentes ne peut être effectuée à une température excédant 49o C.

Dans notre sphère d'activité nous n'avons pas à nous méfier de la contamination présente dans les unités horizontales.

We have only demonstrated the Magnaflux particles and the use of another family product are prohibited unless previously demonstrated to the authorized inspector.

Dry particles consist of a mixture of spheres and elongated needles, which provides good mobility and sensibility.

Magnetic particle examination shall not be done on surfaces whose temperature exceeds 500'F when yellow powder is used, 600'F when using black and red powder and 750"F with grey powder.

The wet particles shall be suspended in a suitable liquid medium and agitated mechanically or otherwise to maintain them in suspension. The concentration of the particles shall be verified at the beginning of each inspection period through the use of an ASTM 100 ml pear-shaped centrifugal tube. The concentration of the wet visible particles shall be maintained between 1.2 Io 2.4

ml. The concentration of the wet fluorescent particles shall be maintained between 0.1 to 0.4 ml per 100 ml of suspension.

The examination with visible and fluorescent wet particles shall be carried out at a temperature not to exceed l20o F.

Contamination as possibly found in horizontal bath is not a matter of concern in field application such as our.
