Re: [MW:35001] Cold pass

2. Normally the Root is more prone to pitting corrosion and to avoid Pitting corrosion problems and to pass the G48 corrosion test of 4g/m2, SDSS which has a higher PREN of 40 & above and higher CPT temperature is used in Root pass. Only Base material that will be in Solution annealed condition has the more stringent requirement of 1 g/m2 due to its near 50/50 Ferrite/Austenite ratio.

Dear Experts,

1.Can anyone tell me what is meant by Cold pass in Dss/Sdss welding. Also please tell me the difference between Hotpass and Cold pass.

2.In DSS Pipeline welding Root pass is being performed with SDSS consumable and rest is performed with DSS consumable.  Can anyone explain me why it is performed like this

Thank you
