Heat Treating Quality & Inspection

Description

This course is designed to increase the technical knowledge of those involved in the heat treatment of metals and alloys. Emphasis is on process control and quality control inspection procedures, since both are necessary to provide heat treated products to meet industry standards and specifications.

Target Audience

Product development, quality control, design and process engineering, production, supervision, sales, and purchasing personnel involved in heat treating will find it a valuable technical education.

Required Pre-Requisites

ASM's Elements of Metallurgy course.
