AWS-CWEng Certified Welding Engineer Part 1 & 2

Introduction

This course covers the qualification requirements for Welding Engineers. It describes how qualifications are determined, and the practice by which qualification may be attained and maintained. The course will evaluate the qualifications of each individual, and provide examinations to test the individual’s knowledge in engineering skills and knowledge as well as their ability to apply the principles of welding engineering. The course is intended to supplement the minimum requirements of employers, codes, other standards, or documents and shall not be construed as a preemption of the employer’s responsibility for the work or for the performance of the work. It shall be the responsibility of employers to determine that their employee, who, having qualified as a Welding Engineer, is capable of performing the specific duties involved in their career assignments. Further, the course will also discuss the basic science fundamentals, simple calculations, special and trigonometric functions; the algebraic equation, graphs and equations, geometry, hyperbola, parabola, complex numbers, calculus, statistics and simple correlation; the unit conversion, mass, weight, volume and density, force, energy, work done, power, stress and strain; the Hooke’s Law, moment and momentum; measuring temperature, heat, thermocouples and pyrometers; classifying thermal properties of material; and the various chemistry symbols, molecular weight and stoichiometry, acid and bases and balance chemical equations. During this interactive course, participants will learn the gas combustion reactions and oxidation-reduction reactions; the ideal gas law, mass balance, bulk and chemical analysis methodologies; the reactivity, toxicity, environmental effect and disposal; the applied science fundamentals, electricity, Ohm’s Law and Kirchoff’s Law; the resistance loss and current rectification, proper handling of power generation, AC/DC and polarity; and the power factor, electromagnetic properties, right-hand rule, devices and principles of current and voltage measurements. Moreover, a person with the demonstrated education, experience, and knowledge as defined by this information and who successfully passes the required examinations is considered qualified as an AWS Certified Welding Engineer (CWEng).
