登录入口 Welding program director James Love has a challenging assignment for students enrolled in his second semester class, Introduction to Layout and Fabrication.

Students are required to construct a 4-inch by 4-inch carbon steel cube with a precise 2-inch cutout on all six sides.

Love explained this intricate project gives him the opportunity to teach students how to create a layout plan with detailed measurements on paper, followed by transferring the layout from paper to the actual material.

学生学习公差，这是一个项目允许的误差量。 在立方体项目中，八分之一英寸的公差是可以接受的。

Students also learn how to make allowances for kerf lines, which are the amount of material taken off during the cutting process.

Take-offs are another critical factor where students are expected to accurately deduct the thickness of the materials in their calculations.

Students learn three different types of cutting processes and are given the choice of what cutting process to use.

随后进行研磨，以确保光洁度，然后组装零件。

Students weld up all seams of the cube using one of four processes: shielded metal arc welding, gas tungsten arc welding, flux cored arc welding or gas metal arc welding.
