	~~The~~ OSE Metal Fabrication Certificate is the first in OSE's line of certification based on well-defined criteria and testing. The basic test involves MIG welding, torching, grinding, drilling, marking, tool selection skills, and others. These skills are based on a generalized skill set indispensible to effective functioning in OSE build events.

	The method of certification involves: (1) skills presentation by instructor; (2) hands-on practice by individuals; (3) Self-exam and documentation on wiki (see [[Fabrication Exams]]; (4) instructor-verified checklist of approved fabrication tasks.

	Grading is based not on pass/fail basis, but on a method that fosters continuous improvement. As such, an Exam is simply a documentation of someone's skill set - and involves taking pictures and notes of a person's results based on well-defined tasks. These are documented on the wiki as the category [[Category:Certification ~~Exams]].~~

	~~=Tool Selection=~~
	What tools to use for cutting, drilling, holes, severing, measuring, bending, forming. Limits to bending metal. Limits to heat bending. Bending with a shop press. Deciding what tool to use for cutting shaft, thin tube, rebar, flats based on weight, length, precision requirement, speed of cut, temperature of cut, and purpose. Tolerancing of tubing holes. Cutting holes based on diameter, thickness of material, and speed.

	~~=Holemaking=~~
