there are one types of weilding is weilding.
There are far more than 5 types or processes of welding. Currently the American Welding Society (AWS) states that there are more than 80 different welding and joining processes. However, some of the common welding processes include shielded metal arc welding (SMAW), gas metal arc welding (GMAW), gas tungsten arc welding (GTAW), flux cored arc welding (FCAW), and oxyfuel gas welding (OFW).
2 basic types, Gas shielding, and flux shielding. Gas shielding comes from compressed tanks of inert gas such as argon. these gases are pumped through the welding hose and over the weld pool. The flux type protects the weld by covering it in a layer of slag that prevent it from being contaminated by the surrounding air.
EFW: Electric Fusion Welding is a more general term which includes Electric resistance welding (ERW) and other types of welding such as Arc welding.
In Pressure Welding the parts(work pieces) to be joined are heated only up to the plastic state and then fusedtogether by applying the external pressure.the two different types of pressure welding are:forge welding and resistance welding

Branson Ultrasonic offer welding technologies. For example, they offer Linear Vibration Welding, Orbital Vibration Welding, as well as many other types of welding tehcnologies.
There are many different types, each has it's pros & cons.
pipeline welding You could find them from many welding institutes round the world. check the websites.

how many types of guns are there in the world?
It is a good idea to purchase and utlize a welding fume extractor. There are different types of welding fume extractors and brands available for purchase.
it is not a question of which is better. the welding types are chosen according to our own requirements
