VRTEX Project Based Lessons - Lincoln Electric

5VrteX® ProjeCt based LessoNs: Overview© 2013 The Lincoln Electric Company

OverviewThe VRTEX® welding simulators are virtual reality welding trainers. This computer based training system is an educational tool designed to allow students to practice their welding technique in a simulated environment. The interactive system simulates arc welding with realistic puddle graphics and sounds. It promotes the efficient transfer of welding skills from the classroom to the welding booth, while reducing material waste and energy consumption associated with traditional welding training.

VRTEX® welding training systems have proven that welding education is more effective and efficient with a blended training approach. Hands on welding training combined with virtual welding training provides an opportunity to practice, develop and refine proper welding body position, technique as well as learn from student interactions and collaboration. Lincoln Electric’s Project Based Lessons for the VRTEX® is a set of lessons that can be implemented into current welding curriculum. The lessons are designed with reference and ties to the educational common core standards as well as the American Welding Society SENSE standards. The project based learning is an effective educational model that allows students to benefit from:

• Solving complex problems in a multi-disciplinary approach• Utilizing fundamental skills (reading, writing, and math) • Incorporating 21st century skills (teamwork, problem solving, research gathering, time management,

information synthesizing, utilizing high tech tools)• Targeting multiple and various styles of learning

• Motivating students with technology and engaging learning processes

Welding Safety

Safety is the utmost importance while performing the lab exercises. Please refer to the E205 Safety Guide and review Arc Welding Safety Practices before starting any lab session. You can also view this guide online at: http://www.lincolnelectric.com/en-us/education-center/welding-safety/documents/e205.pdf. Also, refer to the current Safety Requirements listed in the Operator Manual Safety Procedures and Responsibilities.

Setting Up the VRTEX® Using a Welding Procedure Specification (WPS)

OBJeCtiVeS

Upon completion, the trainee will be able to do the following:

• Read and comprehend a Welding Procedure Specification (WPS)

• Extract important information from the WPS

• Set up the VRTEX® welding simulator according to a WPS

MateRialS and PRePaRatiOn

• VRTEX® Virtual Welding Arc Simulator

• VRTEX® Welding Procedure Specification (WPS) booklet

diSCUSSiOn / QUeStiOnS

1. What is a Welding Procedure Specification (WPS)? 2. Identify the importance of a WPS.

SteP 1

Identification of key welding setup parameters

• Using the following WPS, identify and circle

» Welding position

» Joint type

» Welding process

» Filler metal

» Gas type

» Gas flow rate

» Polarity

» Wire feed speed (WFS)

» Volts

» Material Thickness

• Investigate the proper metal for the material specification provided in the WPS in Figure 1.1.

• Write the metal identified on the WPS next to the material specification.
