With an engineering team, led by our Technical Director and European Welding Engineer, Richard Knowles, we are able work with clients to solve the complex problems they encounter. Advice on base material selection, weld overlay suitability, and heat treatment processes to achieve the desired results is available.
Project: Inlay of ‘Y’ Pieces using Alloy 625
Base material: ASTM A707 (modified L5)
Weld overlay material: Inconel 625 (Alloy 625)
Whilst we could demonstrate PQR inlay experience on A707 material, bore to bore programming of the TIG cladding machines and operator expertise, we could not demonstrate all of these parameters on a ‘Y’ piece configuration and decided to undertake a development project to verify our capability.
By making trial mock up test pieces we were able to develop welding procedures and parameters that could then be applied to full scale production mock up. Once we had proved that the PQRs and welding techniques developed on the mock up pieces gave the required chemical analysis, micro structures and hardness structures demanded by the project we were able to move onto successful production and delivery of the ‘Y’ Pieces.
