Klas Fitting pou WP Grades
| CR | Kowozyon ki reziste klas. Klas S jiska WU pa aplike. |
| WP-WX | RT tout soude avèk oswa san metal filler. |
| WP-WU | UT tout soude avèk oswa san metal filler. |
| WP-S | San pwoblèm |
| wp-wp-WP | Soude, RT, oswa UT tout tiyo kòmanse soude materyèl ki fèt ak metal filler. Tout soude manifakti fitting eksepte jan sa eskli nan A/SA403 paragraf 5.4.3. Si yo ranplase UT pou RT, tout soude yo dwe egzamine 100 pousan pou longè yo jan sa mande A/SA403 paragraf 5.6. |
| WP klas-klas-klas | Mete nòt (321-321H) ak klas (S, W, WX, oswa WU). Aplike nan ekipman ki satisfè tout kondisyon chimik ak fizik nan tou de klas yo. |
