Use of Design of Experiments (DOE) Methods in Materials Joining Research

Posted by | August 15 2017
Design of Experiments (DOE) methods have been used as a tool for industrial research for many decades. These methods allow empirical correlation between defined input data factors and any number of responses from the process of interest.  For example, in resistance spot welding input parameters might be current, weld time, and force. Responses would then be weld diameter, nugget penetration, joint shear strength, etc.  The experimental designs themselves are essentially input factor combination arrays. These arrays are used to map process response using relatively simple linear equations. Designs are selected to provide differing resolution of the resulting correlations between input…

Increasing Weld Penetration with Unique Process Can Improve GTAW

Posted by | August 11 2017
Ian Harris, EWI Technical Director of Aerospace Solutions, recently published an article titled Detailing DeepTIG: How Increased Weld Penetration Can Improve GTAW Results. Co-authored with Yehuda Baskin and Philip A. Baskin, the article appears in the July-August 2017 issue of Practical Welding Today. A patented process called EWI DeepTIG uses specialized metal oxides to increase weld penetration in gas tungsten arc welding (GTAW). It uses proprietary oxide formulations which, when applied to the surface of the workpieces to be joined, increases weld penetration and consequently enhances process productivity. It has been shown to improve weld penetration in GTAW by up to 300 percent. To…

New article: Understanding Collaborative Robot Safety

Posted by | August 10 2017
The introduction of collaborative robots (cobots) into the marketplace brings new standards for safe interaction with this new robotic technology.   Cobot safety starts with understand the collaborative application and what technology is required to meet the safety needs.  Once the technology is determined then a methodical risk assessment is done and the correct standards are followed to reduce the safety risk in the work cell. A new article by EWI Senior Engineer Mike Garman, Understanding Collaborative Robot Safety, provides an overview of what standards apply to collaborative robots, an example of the risk based assessment process flow and a brief summary of…
