Sir Humphry DavyIt was not until the 19th century that welding, as we know it today was invented. Edmund Davy of England is credited with the discovery of acetylene in 1836. The production of an arc between two carbon electrodes using a battery is credited to Sir Humphry Davy in 1800. In that year, SirContinue reading “HISTORY OF WELDING”

WELDING!!
HOW IS WELDING DONE Arc welding uses an electrical arc to melt the work materials as well as filler material (sometimes called the welding rod) for welding joints. Arc welding involves attaching a grounding wire to the welding material or other metal surface. Once that lead is pulled away from the material, an electric arcContinue reading “WELDING!!”
What are the four types of welding.
More than 30 different types of welding exist, and they range from simple oxy-fuel to high-tech processes such as laser beam welding. However, only four welding types are used commonly, and they are MIG, TIG, Stick and Flux- Cored arc welding MIG(Metal Inert Gas) MIG welding is an arc welding process in which a continuousContinue reading “What are the four types of welding.”

WELDING TIPS Hydrogen is welding enemy Hydrogen is the worst weld-destroying impurity around. Because it is everywhere (in water, dirt, rust, paint, manure, grease), hydrogen is a huge challenge for welders. What can be done to gun down hydrogen? Clean, clean, and clean some more. “Hydrogen, along with high-residual stress and crack-sensitive steel, may resultContinue reading “what is welding?”
