DOE-2: Application of Design of Experiments for Spot Welding Process
Dear Friends, we hope you have seen our first video on Introduction to Design of Experiments DOE)! Here is my second video on DOE! I have illustrated a case study of DOE application to Spot Welding process! The Case study is about application of Full Factorial Design with three factors, each at two levels. The video assumes that viewers have seen our first video on Introduction to DOE. In this video, I have illustrated the structure of DOE Full Factorial Design. Analysis of the experiment for main effects, interactions, main effect and interaction plots is discussed with graphics and animations where appropriate for easy understanding of the concepts. The video will be useful for all those who want to learn the technique of statistically designed experiments and also to all those who wish to prepare for various exams by American Society for Quality (ASQ).
In my next video, I will explain how to establish a regression equation and use it for optimization using SigmaXL software.Video is created by Hemant Urdhwareshe who is Fellow of ASQ and is certified by ASQ as MBB, CRE, Certified CQE and CMQ/OE.

Hi Professor, thanks for your useful video. I have a question, if one factor is an exponential factor, which brings a huge difference between two levels, do we still expect average as the way to calculate main effect?

By exponential factor, I think you mean the response is exponential. In that case, either try using a log transformation for response or you may need to use response surface design.
Sir have you any video of applying annova analysis on L9 Tagauchi table

At the moment no. How many runs do u have?
Thank you very much for these simple and helpful videos. I have one question, you have clarified how to calculate the value of interaction for two values. My question is how to know the interaction of the three factors ABC.
@instituteofqualityandrelia7902

Calculation of three factor interaction is similar. Make a column, calculate the algebraic multiplication and calculate interaction.
I thank you for your informative videos. I want to optimize the experimental conditions for a qualitative (pass / fail) type of test. Kindly suggest what type of 1. design of experiments can be used to optimize such tests 2. statistical analysis can be use to check validity of the test results Example/literature references in the replies will be highly appreciated.

Hello Avik! Thank you! For pass fail, you should preferably conversation the response in to variable data, wherever possible. The other choice is increase sample size for each treatment and proportion becomes your response. Proportion of fairly large sample sizes can be considered approximately Normal. Hope this helps.
How could I find the best/worst spot between values for exemple: Which combination gives the highest and lowest strenghts?
@instituteofqualityandrelia7902

It can be determined using the regression equation.
Thank you for this video. I am not able to understand the workings of the pivot table

Ok. You can get dozens of videos on pivot tables. For example this link: kzread.info/dash/bejne/dJ-h2tSvecmqd6Q.html.
You still did not answer the starting question of which combination is the best for our use? How do we find that?
@instituteofqualityandrelia7902

The best combination is determined using the regression model. If you use Minitab, you can use response optimizer. In XL, you can use solver. I am giving a generic answer to find optimum settings. Often there are other constraints such as cost or some other response. In that case, we need to optimize multiple responses.

Why cant professors simply explain it this way... i dont need him/her repeating exactly whats on the books. If the student is interested in the theory he/she can go to the book. Lectures should be about simplification via practical problems.
