The resistance welding method is known to create less pollution and it is a very effective means of welding. Under this method, the most commonly used welding process is the stop welding.

Welding is the method of joining two or more metal objects together using a mixture of heat and electrical energy. Resistance welding uses the thermal properties of metals to combine them jointly. Spot welding concentrates on exact points to weld instead of connecting whole metal objects. Spot welding can too be used to do repairs on before welded things.

Know Your Metals:

There are many things that you should do for the preservation of electrodes. This is, to keep the electrodes safe until you use it again for the next project. The self preservation of electrodes depends upon the properties of the electrodes themselves.

MIG welding is also known as metal gas inert welding? This welding process requires a constant supply of voltage and current from a direct source.

A leak testing in welding is done to makes sure that no gas leaks out from small holes and defects in the pipe. The test is done by first passing air or high pressure gas through the pipes.

Plasma Arc Welding (PAW) uses electrodes and ionized gases to produce a very hot plasma jet aimed at the weld region. The upper energy concentration is useful for deeper and narrower welds and amplified welding speed.

For flux cored arc welding, wire fed machines are used. The metals that are to be joined are melted first and then joined with the help of a consumable electrode that is continuously fed.

There are two types of electrodes that are used normally during a welding process. This can be a consumable electrode of a non consumable electrode.

Using a welding machine that has an AC, alternating current output is very ordinary as there are lots of these welding equipments in the world nowadays. But simply so that you know a mig welder is normally DC output. It is cheaper and easier to create an easy alternating current welding machine than it is to create a DC output machine.

Welding is the art wherein two or more metal or alloy work pieces are joined together with the help of heat energy and electricity. A molten hot solution is allowed to settle down upon the two pieces which is then allowed to cool down to form a strong between the pieces. Thus from the above definition, it is very clear that without heat energy and electricity it is undoubtedly impossible to weld components together.
