Arc welding is a form of welding procedure by using an electrical arc
To generate heat to melt and weld together metals by heating an inert gas. An electric current is produced between the welding base material and a consumable or non-combustible electrode by using either alternating (DC) or direct (AC) current. The consumable is most often a lead-free filler metal such as aluminum, tin, steel, or copper. The method uses both the electrical and chemical properties of the metal to transfer heat from one surface to another.
MIG welding is another common type used for metal fabrication welding. This type produces very clean welds that can be seen on the film. The metal surfaces are heated to a temperature above than the metal’s melting point, which causes the metal to expand to a molten state. The expanding molten metal is then pushed through a stuttering nozzle at a faster rate than the rate of cooling of the surrounding surroundings, which produces a strong weld. MIG welding uses a rotating magnetic field to help induce intermittent electrical currents along the welding point.
Stick welding, also known as stick arc welding
Uses tungsten electrodes in the welding procedure. Tungsten electrodes have been provided with special channels to help channel the welding energy to avoid dangerous plasma spurts. Because tungsten electrodes have been specially designed to produce high-quality welds, this is one of the most preferred welding processes in industry. It is one of the most commonly used techniques for soldering aluminum, copper, brass and stainless steel.
MIG welding and stick welding differ in regard to safety and output. MIG welding generally produces a cleaner weld because of the shorter pulse arc length used. It also typically produces a higher quality weld because of the increased skill level required. On the other hand, stick welding produces a lower quality weld that is sometimes susceptible to feed-back or excess erosion.
The difference between the two processes is the distance between the welding point and the electrode
MIG welding uses a small rod, while stick welding uses a longer rod to produce a greater amount of power with each pulse. MIG welding electrodes are made of steel core which is pressed into a sleeve or plug, while stick welding electrodes are made of aluminum or other metal. In addition, MIG electrodes are available in different length; however, they can be connected in only one way, while stick welding electrodes can be disconnected without damaging the work. An important distinction between the two is that the MIG process uses a constant current source to operate; while the stick process uses an alternating current.
MIG welders and stick welders are very different from each other in the way that they work. MIG welders use an external electric current source to activate the welding equipment; while stick welders work by injecting the current through the welding material to the weld. The MIG welder is used in more difficult welding conditions while the stick welder can be used in a wide variety of welding conditions. The differences between these two types of welders is often the deciding factor in the type of welding task. While the choice between MIG and stick may be the biggest factor in a welding project, the quality of the end product is what really determines whether to use one or the other.
