Abstract

Virtual reality arc welding systems that provide virtual reality simulations for training purposes. Virtual reality welding systems to aid in training welding students may provide a programmable processor-based subsystem, a rendering engine, an analysis engine, and recommended corrective actions based on virtual testing results.

Claims

1. A simulated welding system, comprising:

a mock welding coupon;

a mock welding tool for simulating a welding process on the mock welding coupon, wherein the mock welding tool is configured to be spatially tracked by a spatial tracker when manipulated by a user relative to the mock welding coupon; and

a programmable processor-based subsystem operable to execute coded instructions, the coded instructions cause the programmable processor-based subsystem to;

simulate a weldment responsive to the user'"'"'s manipulations of the mock welding tool relative to the mock welding coupon, wherein the weldment includes defects resulting from the manipulation, by the user, of the mock welding tool relative to the mock welding coupon;

simulate a test on said simulated weldment to generate test data corresponding to at least one characteristic of said simulated weldment, said at least one characteristic corresponding to a physical property of a weld;

compare said test data to predefined welding standards to determine whether there is a defect in said simulated weldment; and

output recommended corrective actions to a display based at least in part on said test data.

2. The system of claim 1, wherein the recommended corrective actions for the user include changes to the user'"'"'s welding techniques.

3. The system of claim 1, wherein the recommended corrective actions for the user include training materials stored on the simulated welding system to be reviewed by the user.
