Explosion cladding is a solid state welding process that uses precision explosions to bond two dissimilar metals while retaining the mechanical and corrosion properties of both. The process is most commonly used to clad steel with a thin layer of corrosion-resistant alloy metal, such as stainless steel, brass, nickel alloys, titanium, zirconium and tantalum. This presentation provides an overview of the explosion cladding process with a focus on applications in the chemical process industry, including columns, towers, reactors, heat exchangers, piping and tanks.

This will be followed by a discussion of quality assurance, in-service inspection, failure analysis and fitness for service.
Webinar 9: Stress Relief Cracking in High Temperature Alloys (2019)
Instructor: Rishi Kant, Lehigh University
Many alloys used at high temperature exhibit stress relief cracking (SRC) during welding and/or post weld heat treatment (PWHT). This form of cracking typically occurs along the grain boundaries and results in a low ductility fracture. The problem is often associated with precipitation strengthening of matrix and localization of plastic deformation at grain boundaries to relax residual stresses from welding. In this work, we considered the effect of variations in PWHT temperature and cold working on the SRC susceptibility of a range of austenitic and ferritic alloys (Inconel 617, 740H, Haynes 230, 282, 347H, Grade 22 and 22V). Gleeble-based tests were developed that accurately simulate the cracking mechanism and provide very good control over temperature, stress and strain. The test results were rationalized based on detailed microstructural characterization and well-established concepts from literature. Six measures of SRC susceptibility were also identified and combined with concepts of Risk Priority Number (prioritization tool in 6-Sigma) to devise a ranking methodology for SRC susceptibility of alloys.

Webinar 12: Welding Metallurgy of Duplex Stainless Steels (2020)
Instructor: Ravi Vishnu, Outokumpu
The historical evolution of different generations of duplex stainless steels will be traced and it will be shown how welding metallurgy has played a central role in these developments.
One impediment to the successful use of duplex stainless steels today is an incomplete understanding of the relevant standards governing welded constructions. An attempt will be made to present a nuanced understanding of different requirements in the codes related to welding. One common source of confusion is the differences in the requirements in many national and international standards. The differences will be highlighted, and an effort will be made to explain why they may have arisen.
Webinar 13: Sealing Non-Metallic Flange Joints – Challenges and Considerations (2020)
Instructors: Matt Tones and Jim Drago, Garlock Sealing Technologies
A new FRP tank requires a metal gate valve with raised face flange to be joined to one of the tank's flanged nozzles. The rubber gasket originally specified won't work, due to media incompatibility...what's next? Non-metallic pipe systems are commonly specified when corrosion is of chief concern and the cost of exotic metals is high. There are basic and special considerations for the selection and application of gasket materials.

Webinar 15: Polymer Based Materials for Chemical Handling: Past, Present and Future (2021)
Instructor: Pradip Khaladkar, MTI
Polymer-based materials have been used since wooden vats were found to be corrosion resistant for pigment and dye manufacturing and properties of vulcanized rubber were discovered in 1832. Many materials have been invented since that time, and these materials are now commonly used for applications ranging from corrosion resistance to product purity. This presentation traces the evolution of polymer-based materials leading to the current state of the art. It reviews the challenges they face in the future and how the industry is responding to the critical issues related to accelerated testing for compatibility, nondestructive and non-intrusive testing for condition assessment and fitness for service evaluation.
