Singapore Shot Peening Seminar
Shot Peening Seminar Day 1
June 25, 2019 – Tuesday
Novotel Clarke Quay – Level 5 – Paprika Room
| Start | Description | |
| 08:30 | Check-in Pre-registered attendees should arrive during this time to sign in and collect reference materials (30 min) | |
| 09:00 | Seminar Opening and Introduction to Shot Peening by EI SPT 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. (40 min) | |
| 09:40 | Peening Media by EI SPT 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. (30 min) | |
| Break (20 min) | ||
| 10:30 | Intensity Basics & Calculation by EI SPT 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. (60 min) | |
| 11:30 | Saturation Curve Practice 1-3 by EI SPT 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. Calculation device required 30 min) | |
| 12:00 | LUNCH – Buffet style in hotel restaurant (60 min) | |
| 13:00 | Peening Coverage and Masking by EI SPT as part of FAA course material. This session outlines Coverage requirements for the peening process. We discuss why Coverage is important and how to inspect for proper Coverage. A brief outline of part masking options will also be discussed. (60 min) | |
| 14:00 | Study Break (20 min) | |
| 14:20 | Level 1 Written Exams (50min) | |
| 15:10 | Break / Dismissal (10 min) | |
| 15:20 | Rotary-Flap Peening Introduction by EI SPT as part of FAA course material. Rotary Flap Peening has been embraced by the aviation industry. 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” 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. This session will feature a closed loop Rotary-Flap peening motor. (60 min) | |
| 14:20 | Rotary-Flap Practical & Exam Session 1 by EI SPT as part of FAA course material. These sessions are exclusively for those participants that are testing for the Rotary Flap certificate. A pair of students will undergo practical testing per SAE AMS-2590 requirements, then will take a written examination to comply to FAA course requirements. (60 min each – limited availability) | |
Shot Peening Seminar Day 2
June 26, 2019 – Wednesday
| Start | Description |
| 09:00 | Level 1 Exam & Concept Review and Discussion – (20 min) |
| 09:20 | Media Inspection and Maintenance by EI SPT 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. (60 min) |
| 10:20 | Break (20 min) |
| 10:40 | Advanced Intensity – Parameter Adjustments by EI SPT 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. (60 min) |
| 11:40 | Advanced Saturation Curve Practice 4-6 by EI SPT 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. Calculation device required (20 min) |
| 12:00 | LUNCH – Buffet style in hotel restaurant (60 min) |
| 13:00 | Advanced Saturation Curve Practice 7-8 by EI SPT 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. Calculation device required (15 min) |
| 13:15 | Advanced Coverage and Surface Texture by EI SPT as part of FAA course material. For the process engineer, this session discusses how to determine part processing time to insure proper coverage while avoiding peening parts for too long. Solutions for hard to peen locations are also discussed. (60 min) |
| 14:15 | Procedures & Processes by EI SPT. For process engineers and managers, this session will; outline and discuss the standard peening procedure, review J443’s allowance for efficiently verifying intensity of test fixtures with multiple Almen test strip locations, explain how residual stress curves are generated and what they tell us, discuss optional secondary processes that further improve fatigue life, and speculate on the requirements of an upcoming SAE manual peening specification and why it’s important. (40 min) |
| 14:55 | Study Break / Dismissal – (20 min) |
| 15:15 | Level 2 / 3 – Written Exams (60 min L2 / 90 min L3) |
| 16:30 | Level 2 Exam & Concept Review and Discussion – (20 min) |
| 15:45 | Rotary-Flap Practical & Exam Session 2 by EI SPT as part of FAA course material. These sessions are exclusively for those participants that are testing for the Rotary Flap certificate. A pair of students will undergo practical testing per SAE AMS-2590 requirements, then will take a written examination to comply to FAA course requirements. (60 min each – limited availability) |
