Welding Basics for the Process Engineer

William N. Weaver, P.E. and John C. Huang, Ph.D., P.E.

Course Outline

Welding is perhaps the most common “joining” process used in the construction of a process facility; it is generally used to construct the structures, connect the pipes and fabricate the equipment for the facility. It thus becomes critical that the Process Engineer (and others) understand the basics of this technique.

This course provides a base upon which a detailed understanding of the welding processes can be built. An understanding of some of the various welding processes is provided along with key points, which need to be specified by the engineer in order to maximize the benefits of welding to his facility.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.

Learning Objective

At the conclusion of this material the student will:

Intended Audience

The intended audience is engineers responsible for fabrication, specification writing and inspection of process equipment, piping and facilities.

Benefits to Attendee

On completion of the course the student will have increased his / her understanding of the welding process and how they can benefit the student’s facility.

Course Introduction

This course offers an introduction to the various portions of the welding process that require specification and attention in order to gain maximum benefit for a facility. Avoidance of problems related to welding is critical to having usable facility structures, equipment and piping systems.

Course Content

The material contained in this course covers welding processes, weld types, welding safety, weld specifications and communication of weld needs between the specifying engineer and welder. Inspections of the completed welds is included.

Course Summary

Welding is a valuable tool for the engineer to use to create facilities and objects and this technique provides a rapid, well established and inexpensive approach to fabrication. Understanding the basics makes proper designing easier. The welding process offers a wide range of opportunities to the engineer for fabrication of his designs.

The field of welding is broad with many applications in industry and we have certainly not covered all aspects of the process here. Several universities offer degrees in welding engineering, this offering is indicative of the breadth of the field.
