Experimental Surface Tempering Treatment Using
Energy from Arc Welding - Application for Flat Products.
• Implementation, analysis, synthesis, and evaluation demonstrated in the
application of the Taguchi method and univariate method in the heating process, thereby
ing the optimal set of parameters and constructing graphs showing the relationship
between factors and hardness.
• Design, fabrication of a system, component, or process to meet the specified
requirements with practical constraints demonstrated in the modification of the
microstructure, improving hardness after quenching.
• Capability of improvement and development demonstrated in the extension to
the processing of other surface types such as convex and concave surfaces.
• Ability to use technical tools, specialized software demonstrated in the use of
Minitab, Excel software to build data and analyze the influence of factors on hardness
through the Taguchi and univariate methods.
Following the completion of this topic, the achieved results can be applied in the
post-processing of C45 steel to increase hardness and enhance its mechanical properties.
Finally, the process of carrying out the topic has achieved specific results as follows:
• Establishment of an optimal set of parameters for the quenching process.
• Improvement in surface hardness and microstructure hardness after quenching.
• Modification of the microstructure after tempering.
