what is welding ? how many kinds of welding ?
Answers
Heya...❤❤❤
here is ur answer....
Welding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool causing fusion. Welding also requires a form of shield to protect the filler metals or melted metals from being contaminated .
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.
hope it helps...

TYPES OF WELDING:
Shielded Metal Arc Welding (SMAW) With this particular type of welding, the welder follows a manual process of stick welding. ...
Gas Metal Arc Welding (GMAW/MIG) This style of welding is also referred to as Metal Inert Gas (MIG).
Flux Cored Arc Welding (FCAW) Gas Tungsten Arc Gas Welding.
