Metallurgy of Welding and Joining

ASM HOMESTUDY COURSE (15-Lesson Series)

COURSE OVERVIEW

Almost all industries are engaged in some form of joining to fabricate metals and materials into useful engineered products. This course is intended to teach metallurgical fundamentals involved in structures as materials is being heated and cooled during the welding process. Common materials and alloys of various compositions are included, as well as a large number of various types of welding processes.

Course Outline

1. Survey of Joining Processes: welding of plastics; adhesive bonding; soldering; brazing; major welding processes.

2. Welding Design: types of joints, including butt, lap, tee, corner, edge, composite.

3. Weld Metal Soundness: types of cracking; tests for cracking; metallographic examination; restraint tests; factors affecting weld cracking.

4. Arc Welding Carbon Steels: metallurgical effects of welding; effect of carbon; transition temperature behaviour; practical uses of carbon steels.

5. Arc Welding Low and Medium Alloy Steels: comparison to carbon steel; effect of preheat; effect of postheat; welding technique related to isothermal diagram.

6. High Alloy Steels - Fundamentals: definitions; specifications; high; chromium alloy steels; phase diagrams; microstructure; hardenability.

7. High Alloy Steels - Techniques: welding techniques and procedures for martensitic stainless, ferritic stainless, austenitic stainless

8. Copper and Its Alloys: typical welding applications for copper, brass, bronze, and other copper alloys.

9. Arc Welding Aluminum, Magnesium, Titanium and Nickel: typical welding applications for aluminium, magnesium, titanium, nickel, and their respective alloys.

10. Inspection of Weldments: duties of an inspector; imperfections in weldments; discontinuities in weld metal; inspection methods; destructive testing of welds; nondestructive inspection methods for welds.

11. Resistance Welding - Fundamentals: basic laws of resistance welding; types and properties of resistance welds; joint designs; processes.

12. Resistance Welding - Practice: material specifications; condition and thickness; methods of cleaning; electrode material, shape and size.

13. Electron Beam Welding: penetration and nugget geometry; operational modes; equipment principles; materials joined.

14. Fusion Welding of Steel: sheet steel; various techniques; fusion welding of mild steel plate; welding of steel pipe; multi-flame welding.

15. Hard Facing: improving wear resistance; economics; preparation; lengthening service life; rebuilding worn parts; bronze surfacing.

Who Should Enrol:

If you are involved in welding as a welder, welding inspector, engineer, manager, technician, metallurgist, sales or purchasing, this course can provide you with much technical information in selection of proper materials and welding processes and help solve problems as they arise.
