1. A mock welding unicoupon for a virtual welding system, comprising: a first exterior surface; a second exterior surface perpendicular to the first exterior surface, wherein the first exterior surface and the second exterior surface together provide a plurality of grooves configured for simulation of a plurality of different types of groove welds on the mock welding unicoupon; a curved exterior surface configured for simulation of a pipe fillet weld on the mock welding unicoupon; and a magnet source configured to generate a magnetic field around the mock welding unicoupon for tracking movements of a mock welding tool with respect to the mock welding unicoupon, wherein the magnet source is attached to the unicoupon in a fixed position.
