This course consists of 1 Module on it’s own as it may contain concepts some will find difficult to understand and grasp.
A good welder needs to understand these concepts, which principally gives him/her an understanding as to what is happening to the metals when melted and fused together. It will enhance understanding of the further course modules on NDT and Inspection, the importance of recognizing factors that contribute to a poor weld, and therefore be able to rectify/correct it.
The module consists of a video approx. 10 minutes duration, Course Notes and final Quiz on the theory. There is no practical test.
(When watching the video trailers, it is best to start the video and then immediately pause it, then wait a few minutes to allow streaming before starting play again.)
