Course Summary
This course provides a focused overview of the welded fabrication of nickel-containing stainless steels in corrosion-resistant service, exploring key welding preparation, joint design, process selection and fabrication practices to ensure long-term integrity and corrosion performance.
In industrial environments where corrosion-resistant service is required, the selection of materials and their fabrication method are critical. This course delves into the welded fabrication of nickel-containing and stainless steels, drawing on the Nickel Institute’s guidelines to present best-practice methods across three domains: welder preparation and shop practices; materials and metallurgical considerations; and design-engineer responsibilities. Participants will learn how factors such as embedded iron, surface oxides, joint design, filler metal selection, and process qualification influence weld integrity and corrosion performance. The course further covers specific welding processes (SMAW, GTAW, GMAW, etc.), and how to avoid common defects, design crevices, and ensure proper purging and cleaning.
By the end of the programme, attendees will be equipped to apply fabrication practices that optimise corrosion-resistant stainless steel structures and equipment, reducing failure risk and improving longevity in service.
Learning Objectives
By the end of this course, students will be able to:
- Explain the key physical properties of nickel-containing stainless steels that affect welding and fabrication.
- Identify common welding processes (SMAW, GTAW, GMAW) and select appropriate filler materials.
- Apply best practices for weld preparation, execution, and post-weld cleaning to prevent defects and corrosion.
- Describe how welding influences the metallurgical and corrosion characteristics of different stainless steel alloys.
- Recognize design features that minimize crevice corrosion, embedded iron contamination, and other failure risks.
- Select, handle, and specify stainless steel materials to ensure long-term corrosion resistance and performance.
