1. VWTS The new educational course for welders Holger Havenith Uwe Koppel Heinz M. Klein

2. Table of contents • Activity oriented educational concept • Training course MAG fillet weld/butt weld in accordance with guideline IIW 1111 – „International welder“ • OutlookEducation using VWTS as an International WelderDevelopment of VWTS

3. Ability for adjusting parameters Good manual skills Self evaluation of the welds Target: Improvement of the quality of education of welders Demands on welders

4. Increasing degree of difficulty- from easy to difficult - taking of welders‘ exams of one level (P FW, P BW, T FW, T BW) Differentiation into the fields of thin sheet and plate materials etc. Completely program on special knowledge Education model acc. to guideline IIW 1111 – International welder

5. Principles of education • Activity oriented learning • Planning/anticipating • Performing • Verifying/Evaluating/Assessing Performing Verifying Complete action Planning

6. Education is performed on the 4-stages principle Preparation Presentation Performance Conclusion The more learning channels are activated, the more remains in long-term memory VWTS activates all learning channels: hearing, the eye, emotions, practical action, discussions… Phases of self-learning and trialwill support the capability to act Teaching principles for working on the VWTS

7. Formation of groups on a system Create extensive phases of trial for the trainee Intrinsic motivation due to competitions Immediate feedback by the system andtrainer during the welding process Trainer can observe several participants(Working in natural light more than in the booth) New opportunities due to VWTS

8. Scope of use Relation trainer- participant Requirements on shop size Minimum requirements of the systems used Requirements to trainers and futuredemand on qualification Draft of a guideline DVS 1108-1

9. Primarily at the beginning of the training and for beginners in the welding process, respectively For every new position in the field of thin sheet and thick plates Every time the manipulation of objects and torch are presented to groups Max. two half days per position Use of the systems

10. Training MAG fillet weld / butt weld - Curriculum Basis: DVS-IIW-guideline 1111 „International welder“ Implementation to common training Orientation to educational practice of the educational centers Duration of eight weeks Still low proportion of VWTS in the education (due to system!) VWTS-use never takes longer than half a day Exact curriculum November 14

11. Training course MAG fillet weld/ butt weld – Teaching principles Use of newteaching possibilities by groups/self-learning Use of new ergonomic possibilities by observing of welder's positions Exact instructions to trainers November 14

12. Overview training PB 3 mm Day 3 1 2 3 4 5 6 7 8

13. Reference to expert knowledge - Grading acc. to progress/level - In the form of questions, films, parameter settings (multimedia) - Explaining of errors during the evaluation Operation acc. to power sources with all parameters Easy change of user with automatic saving of all data Higher position density (all positions acc. to RL 1111 in the system) Future improvement of the VWTS
