Repairability and effectiveness in direct energy deposition of 316L stainless steel grooves: A comparative study on varying laser strategy
Summary:
• This study aims to explore comparative DED repair strategies for repairing grooves with angle cases of 90° and 135° with InssTek's MX-Lab.
• Deposition for repair requires careful design, which is not always performed for deposition on flat or smooth surfaces. So, researchers investigates the factors that deteriorate the metallurgical bonding such as insufficient laser input, obstructed powder supply, dimensional error, and residual stress, an effective groove repair strategy was established.
• A modified DLP strategy for repair was proposed and proved its effectiveness via eliminating defects, achieving exceptional tensile properties. The findings of this study provide insights into the optimization of DED strategies for achieving robust metallurgical bonding within grooves, thereby advancing technological maturity in the field of metal repair.
