120785 - Characterization of Detaclad™ Interface With Simulated Weld Overlay Repair: A Positive Assessment for Cost and Time Savings in Equipment Lifecycle 

In the context of equipment repair and refurbishment, in situ weld overlay on top of existing cladder is not a common practice. Concerns exist regarding the interface's ability to withstand stresses induced by the weld overlay. This study aims to comprehensively characterize the DetaClad™ interface and its behavior after simulating a weld overlay repairing.

When considering weld overlay repair options, preserving the cladding emerges as a highly favorable choice. Weld overlay on top of the cladding offers a cost-effective, time-efficient, and prudent approach to refurbishing critical components. By retaining the cladding, the method minimizes disruption to the base material, preserving its integrity and essential mechanical properties. Moreover, this approach prioritizes safety by mitigating potential hazards during the gouging process.

 

The purpose of this research is to demonstrate that weld overlay build-up on top of DetaClad™ does not compromise the bond quality, nor the mechanical properties of the steel. The test parameters include analyzing the mechanical properties of the interface before and after welding, along with a detailed examination of the mechanical and structural properties of the base and cladder material. In addition, cross section macro and micro examinations are performed to gain valuable insights into their structural integrity.

This study demonstrates that weld overlay on DetaClad™-cladded surfaces preserves the interface integrity and mechanical properties of the pressure boundary. Selecting DetaClad™ during CAPEX can lead to substantial time and cost savings throughout the equipment lifecycle, making it a valuable choice for heavy pressure vessel applications, benefiting engineering decisions in equipment repair and maintenance.
