Technically speaking, MIG welding is arc welding because it uses an intensely hot electrical arc to heat and join the metal together. Usually arc welding means stick welding. The difference between the processes is the manner in which the filler metal is applied. With MIG welding, the filler metal is usually applied with a wire fed through a gun type device with an inert gas such as argon shielding the weld. Arc (or stick) welding uses a solid electrode of the same type of metal as is being joined shielded by a layer of flux. The method of welding depends on the user's skill and what is to be welded.

∙ 16y agoVertical welding is referring to the position a weldment joint. The welding torch will travel parallel to the pull of gravity (specified either up or down.) Easier way to understand this is if your wall was metal you are welding, you weld from floor to ceiling, or ceiling to floor.

∙ 12y agoArc welding uses a welding power supply to create an electric arc between an electrode and the base material to melt the metals at the welding point. They can use either direct (DC) or alternating (AC) current, and consumable or non-consumable electrodes. The welding region is sometimes protected by some type of inert or semi-inert gas, known as a shielding gas, and/or an evaporating filler material. The process of arc welding is widely used because of its low capital and running costs.

In MIG welding what are the polarities of the torch and the work-piece and what is the fundamental reason for this?
MIG welding works only with reversed polarity, DC+, + at the torch. The reason is mostly the stability of the arc. Using DC- will result in a very unstable arc with lots of spatter.
How much thickness of plates weld by using gas metal arc welding?
See preceding question re: Mig welding.
What is MMA welding?
MMA stands for manual Metal Arc welding. In short "arc welding" and can be used in either AC or DC mode. Usually incorperated with Mig, Tig and plasma cutters for arc welding machines as an optional extra. submitted by Ken.Benson - Clarke. sales@edacomputers.co.uk from saffon walden, essex, uk.
In which process is the electrode used in welding?
Manual Metal Arc Welding(MMAW) Also GTAW (TIG) and GMAW (MIG) The MIG wire carries electric current so it is considered the electrode. TIG the Tungsten is considered an electrode.
How does length of gas nozzle effect mig welding?
The legth of the gas nozzle can affect the MIG welding process because it modifies the "electrode extension" or so called stickout. The longer the nozzle the longer electrode extension needed to keep the arc away from it thus the value od the welding current and arc voltage changes. These changes will have a great effect on the weld.
What are the types of welding?
Gas, arc, mig and tig.
What is gmac in welding?
Gas Metal Arc Welding Most folks call it MIG
What does mig stand for in mig welding?
MIG stands for metal inert gas. It is a non-standard term for gas metal arc welding (GMAW) and flux cored arc welding (FCAW) according to the American Welding Society (AWS). It is simply Metal Inert Gas.
Is arc welding stronger than mig welding?
Using the correct procedures and filler material they can both have the same strength. P.S. both are considered "arc welding"
What is MIG welding?
It is arc welding process using a spool of wire that is fed to the material by an electric motor. Different from shielded metal arc welding which uses consumable welding electrodes with a covering of flux to assist and protect the weld. The MIG uses an inert gas (IG) to keep impurities from the welding point. The technical term for MIG is GMAW (gas metal arc welding), this is because most of the time an inert gas is not used, a mixed gas is more likely. Ex. 90-10 Ar-CO2

Explain the principle behind arc welding.?
Arc welding uses an electrical current to create enough heat to melt metal. Any type of welding that uses an electric arc is technically arc welding. However, most people use the term 'arc welding' to mean shielded metal arc welding (SMAW), or 'stick welding'. SMAW, MIG, and flux core wire welding use the filler metal as both electrode and filler; TIG welding uses an electric arc to heat the base metal and a separate filler rod to add metal to the weld.

What is the gas for welding?
Oxygen and acetylene for flame welding. Argon for Tig welding CO2 for MIG welding steels Argon for MIG welding aluminum TRI-mix for robotic mig of steels. And helium is added for some overhead welding.
