Shot Peening Workshop
February 8-9, 2011
Melbourne, Australia

 

 

 

Tuesday - February 8th, 2011
Start End Dura Description
8:30 9:00 30 min Workshop Opening and Introduction to Shot Peening
by Dr. John Cammett of EI Education Division as part of FAA course material. This entry level class discusses the history and fundamentals of the peening process that we know today as terms used in the industry are introduced and explained.  This session also defines when the peening process should be performed.
9:00 9:40 40 min Peening Media Basics
by Dave Barkley of EI Education Division as part of FAA course material. The media is the real tool of the peening process.  This session gives an overview of the four types of media commonly used in peening and their attributes.  This class also briefly discusses what to look for when selecting the right media for your application.
9:40 10:30 50 min Intensity Basics
by Dr. John Cammett of EI Education Division as part of FAA course material. This class will introduce the concept of peening intensity and how it is measured using Almen strips, holders and gages. The saturation curve and the 10% rule are explained and guidelines for new set-ups and verification trials for peening intensity are discussed.
  20 Minute Break
10:50 11:10 20 min Saturation Curve Practice
by Dave Barkley of EI Education Division as part of FAA course material. This session explores simplified saturation curves as workshop attendees are asked to plot arc height data in order to determine intensity.
11:10 12:00 50 min Peening Coverage
by Dr. John Cammett of EI Education Division as part of FAA course material. This session defines coverage and its importance in the peening process.  It is often incorrectly associated with intensity and saturation curves.  This class will discuss why intensity and coverage are two entirely different aspects of the peening process and how they do not affect each other.
12:00 12:45 45 min LUNCH
12:45 1:35 50 min Peening Equipment Basics, Features and Advances
by Kumar Balan of Wheelabrator Group. Blast machines originally intended for cleaning applications have been magically transformed by many users for peening applications too! Part of this presentation will discuss why this may not always be possible, the different process variables and their impact on the final peening results. Common variables in wheel peening and air peening will be presented, with details on their significance. Commonly used specifications and design of equipment for conformance will be discussed. Some of the latest developments in peening machine technology will be introduced to provide a flavor of the future in this industry.
  10 Minute Break
1:45 2:35 50 min Roto-Flapper Peening Lecture
by Dave Barkley of EI Education Division as part of FAA course material. Flapper Peening is becoming more accepted as a reliable peening process for spot-repair.  It is an inexpensive way to apply the peening process in small areas without having to use large blast cabinets.  This session discusses the origins of flapper (roto) peening and outlines how it uses a slightly different set of rules from conventional peening.  Participation in a Practical (hands-on) is mandatory for those seeking to be tested for FAA course credit.
  10 Minute Break
2:45 3:35 50 min Peening Machine Preventative Maintenance and Repair
instructor TBA
  10 Minute Break
3:45 4:00 15 min Exam Preparation and pre-view
4:00 5:00 60 min Level 1 Exam
5:00 6:00 60 min Roto-Flapper Peening Practical Testing
by Dave Barkley of EI Education Division as part of FAA course material.

8:00 8:30 30 min Level 1 Exam Review (optional)
8:30 9:15 45 min Media Inspection and Maintenance
by Dave Barkley of EI Education Division as part of FAA course material. Using the correct media and maintaining its quality is a must for a consistent process.  This session discusses different media specifications and their requirements.  Examples of both shape and size inspection are reviewed and on-machine devices that help meet specifications and maintain media quality are also examined.
9:15 10:00 45 min Coverage and Masking
by Dr. John Cammett of EI Education Division as part of FAA course material. This session looks at problems with coverage including the effects of having too little or too much peening coverage.  The concept of Lean-peening is also introduced.
  20 Minute Break
10:20 11:05 45 min Advanced Intensity
by Dr. John Cammett of EI Education Division as part of FAA course material. This session looks at how other peening parameters can affect the intensity results in your process.  Changes in the media and machine condition can cause undesired results.
11:05 12:00 55 min Peening Applications
by Peter O'Hare of Metal Improvement Co. Learn about the many ways that shot peening is used to improve products from fatigue life improvement and beyond. This session also presents different ways to apply the peening process.
12:00 1:00 60 min LUNCH
1:00 1:40 40 min Advanced Saturation Curve Practice
by Dave Barkley of EI Education Division as part of FAA course material. This hands-on practical asks students to produce slightly more challenging saturation curves and determine an intensity value.  This session also invokes the thought that the saturation curve can be more than just a means to determine an intensity value. 
  10 Minute Break
1:50 2:40 50 min Peening Techniques for Challenging Applications
by Bill Barker of Progressive Surface. Learn about tools and techniques to solve difficult peening configurations with an emphasis on robotic nozzle and part manipulation.
  10 Minute Break
2:50 3:20 30 min A Brief Look at Residual Stress Measurement
by Dr. John Cammett of EI Education Division. This lecture outlines how residual stress is measured and how doing so is the ultimate way to examine how the peening process improves the fatigue strength of a part.
  10 Minute Break
3:30 3:45 15 min Exam Preparation and pre-view
3:45 4:45 60 min Level 2 Exam
4:45 5:00 15 min Exam Review and Discussion
