One word - PRACTICE
it is not a question of which is better. the welding types are chosen according to our own requirements
Using an electrode positive in welding processes can provide advantages such as better penetration, increased welding speed, and improved control over the welding arc.
MIG welding with flux core wire offers advantages such as higher welding speed, better penetration, and increased portability compared to other welding methods.
Flux core welding gas offers advantages such as increased welding speed, deeper penetration, and better performance in windy conditions compared to other welding techniques.

i think roorkee will be batter option
Welding would melt the base metal and filler metal while brazzing only melts the filler metal.
It depends on what metal you are welding and how thick it is, but in general, no. Any process that will raise enough heat for adequate weld penetration is for the most part equal.
Steel is such a commonly used metal that almost any welding machine can accommodate it. Some are better than others though. Steel is usually welded with either sick welding, or wire welding (gas shielded or flux core)
A welding ground is important in welding because it helps to complete the electrical circuit, ensuring a safe and effective welding process. Without a proper ground, there is a risk of electric shock, fire, and poor weld quality. The ground also helps to stabilize the electrical current, resulting in better weld penetration and overall welding performance.
Thorium welding rods offer several advantages over other types of welding rods. They provide better arc stability, higher current-carrying capacity, and improved heat resistance. Additionally, thorium rods have a longer lifespan and produce less spatter during welding, resulting in a cleaner and more efficient welding process.
Vertical up welding is preferred in most instances as better penetration is achieved and the slag does not run down into the arc. Down hand welding is mostly used on thin material so as not to burn thru the metal. Travel speed is usually increased also.
