Types of welding process

Welding is an exciting and rewarding technique for enthusiasts and professionals alike. Using a couple of tools and various types of metals, welders can transform any piece into any shape and design they desire, all with sparks flying around in the process. However, in order to be able to master the art of welding, you need to start with the basics and be aware of the different types of welding processes. 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. Each of them comes with its own advantages and disadvantages and you need to have proper training to practice them.
