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. W. S. English 81 3 .

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.
