Provide a better understanding of the terminology used in the welding industry
Describe the mechanical properties of steel and see how they are tested
Learn about the structure of carbon steel and how to alter its mechanical properties
Review numbering and naming conventions used in the industry
Practice heat treatment techniques used by welders and engineers
Who Should Attend: all maintenance personnel including supervisors, machinists, welders, auto & diesel mechanics, as well as engineers, marketing & salespeople
Time requirement: 3+ hours. (75% classroom, 25% shop)
"Competitive learning" in the classroom, & practical application in the shop.
Before the heat treatment, we bend a hangar until it breaks
noting the force required to bend it - usually 3-4 bends.
(This is repeated after the heat treatment.)
A quench & temper starts with heating to red hot & quenching in water...
Spark testing to identify carbon content in steels
... then reheating slowly to purple, followed by annealing or normalizing
