Assigned by the company Van der Leun located in Sliedrecht I prepared a welding procedure for the welding of Inconel 625 on S355J2+N base material. The welding of these components had to be according to ISO 15614-7 with the additional requirement that there would be a maximum of 5% FE at 5mm above the fusion line. All the testing have been conducted by MME Ridderkerk and took place after Post Weld Heat Treatment by Akkermans Gloeitechniek.
