Welding terminologies and their abbreviations
It is usual practice to write terminologies in shortened form. For this we combine first alphabetic letters of the specific words, which is so called abbreviation. Abbreviations are widely used for the ease of understanding but sometimes we face such combination of letters that we don’t know what they stand for.
Here we listed some common welding terminologies along with their abbreviations in alphabetical order. Scroll down and get the one you searching for.
