Abstract

A simulator facilitates virtual welding activity of boss (e.g., orbital) weld joints. The simulator may include a logic processor based system operable to execute coded instructions for generating an interactive welding environment that emulates welding activity on a section of virtual pipe having at least one virtual weld joint. It also includes a display connected to the logic processor based system for visually depicting the interactive welding environment, wherein the display depicts the section of virtual pipe. A pendant is provided for performing welding equipment setup and virtual welding activity on the at least one weld joint in real time where one or more sensors are adapted to track movement of the input device in real time for communicating data about the movement of the input device to the logic processor based system.

Claims

1. A virtual reality welding simulator comprising:

a logic processor based subsystem operable to execute coded instructions for generating an interactive welding environment that emulates a virtual welding activity at an interface of a first virtual work piece and a second virtual work piece defining a virtual weld joint;

displaying means operatively connected to the logic processor based subsystem for visually depicting the interactive welding environment, wherein said displaying means depicts the virtual weld joint; and

a hand-held input device for performing the virtual welding activity on the virtual weld joint in real time;

wherein the first virtual work piece is a flat plate,

wherein the second virtual work piece is a cylindrical body, and

wherein the virtual welding activity includes a first virtual welding activity on the virtual weld joint and a second virtual welding activity on the virtual weld ioint;

wherein the first virtual welding activity and the second virtual welding activity are connected by at least one tie-in operation.

2. The simulator as defined in claim 1, wherein the hand-held input device emulates a plurality of controls for specifying parameters relating to at least one of the welding environment and the virtual welding activity.

3. The simulator as defined in claim 2, wherein the logic processor based subsystem further comprises restricting access to at least one of the controls based on a user to enhance learning objectives for the user.

4. The simulator as defined in claim 3, wherein the logic processor based subsystem further comprises teaching an interaction or reaction based on at least one of a visual, audible, and physical change to ensure that the user can properly setup the interactive welding environment or can effect error recovery.

5. The simulator as defined in claim 4, wherein the logic processor based subsystem further comprises virtual calculators or tables that allow input and provide an output based on entered values.

6. The simulator as defined in claim 4, wherein the logic processor based subsystem identifies incorrect setup parameters or combination of parameters input by the user.

7. The simulator as defined in claim 6, wherein the logic processor based subsystem determines the proper setup parameters or combination of parameters which should have been entered by the user.

8. The simulator as defined in claim 7, wherein the logic processor based subsystem provides at least one of a visual, audio, and physical indicator of the proper setup parameters or combination of parameters.

9. The simulator as defined in claim 1, which further comprises a simulated camera-based system to track a path of the weld.

10. The simulator of claim 1 which comprises multi-language capabilities.

11. The simulator of claim 1, wherein the cylindrical body is a pipe.
