Types of Welds
Various types of welds that can be made in each of the basic joints

A weld joint might be modified to gain access to the weld joint or to change a weld’s metallurgical properties

Welding Terms and Symbols
Terms and Symbols that can be used to communicate from the weld designer to the welder is essential to proper completion of most weldments.

Weld Type and Joint Weld Configuration
For a welder, it is important to be able to weld in different positions…………
