MOCormac DEPARTMENT OF WELDING The curriculum in welding is designed to prepare a student for apprenticeship training as a welder. The Department of Welding is equipped to give instruction in fusion and bonding of metals using both oxygen, acetylene and electric arc methods. Courses are planned for a transfer as well as for a terminal student. CURRICULUM Welding (Pre-Apprentice) Freshman Year A.

Elementary Acetylene Welding. A course for those with little or no training in acetylene welding. The student is taught how to set up an apparatus, secure balanced flame, reducing flame, oxydizing flame: how to control molten puddle and uniform puddle across work with uniform overlap of ripples; how to make uniform bead with torch and filler rod; also how to join pieces of metal up to one-fourth inch, by butt weld, fillet weld, and lap welding processes. Five quarter hours. Autumn. Staff 52. Elementary Acetylene Welding (Continued). Training on pipe welding of different sizes; T-welds, butt and fillet welds; also steel welding of heavier gauge, brazing of different thicknesses, joining dissimilar metals together, and silver soldering. Some cast iron welding is given. Five quarter hours. Winter. Staff 53. Elementary Acetylene Welding (Continued). A continuation of the skills learned in Welding 51 besides light aluminum welding. Repair jobs of a small nature are encouraged to develop welding skills in a new light such as putting parts back into useful operation. Some metal welding and hard surfacing are given. Five quarter hours. Spring. Staff 54. Elementary Arc Welding. Arc welding of different gauge sheet steel. Striking the arc, controlling the head, selecting amperage and proper rod for the job, joining two pieces together by butt weld. Fillet weld and lap weld are skills mastered in course. Five quarter hours. Autumn. Staff 55. Elementary Arc Welding (Continued). Arc welding of vertical, horizontal and overhead welding, along with welding heavy gauge steel. Some cast iron and pipe welding. Five quarter hours. Winter. Staff 56. Elementary Arc Welding (Continued). Continuation of skills learned in Welding 54. Welding of heavy structural steel, welding of heavy castings, stainless steels and steel alloys. Five quarter hours. Spring. Staff
