What else can I help you with?
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.
Is there an advantage to welding reverse polarity?
Yes, welding with reverse polarity (DCEN, or direct current electrode negative) can offer several advantages, particularly in TIG welding and some applications of MIG welding. It allows for better penetration and a more stable arc, which can improve the quality of the weld. Additionally, reverse polarity helps in reducing the heat input into the base metal, minimizing distortion. This polarity is particularly effective when welding thinner materials or for applications requiring a cleaner weld.
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 a welding machine?
metal inert gas (MIG) welding
MIG welding compared to flux core welding?
Flux core is a type of MIG welding.... please kind of know what your talking about before you ask a question.... Gas assisted solid mig wire welding is neater and cleaner. There are two types of flux core mig welding that you are talking about. 1. Gasless flux core mig wire 2. Shielded flux cored welding wire, uses a shielding gas as well. Most likely you are talking about the gasless mig wire. look here for more info: www.learn-how-to-weld.com/gasless-mig-wire.html
Plasma welding is an extension of?
Mig
What type of gas is used when mig welding steal?
When MIG welding STEEL a mixture of Argon -- CO2 is used. 75% - 25%
What is a automated welding machine?
metal inert gas (MIG) welding
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.
What are the advantages of using MIG welding with flux core wire compared to other welding methods?
MIG welding with flux core wire offers advantages such as higher welding speed, better penetration, and increased portability compared to other welding methods.
Electrode for mig and mag welding?
A tubular or wire cored electrode is used for both MIG and MAG welding. These can be purchased online at places like AGA.com.
How do you calculate wire feed speed in MIG welding?
Wire feed speed in MIG welding is calculated by multiplying the welding current by the wire feed rate. This formula helps determine the speed at which the welding wire is fed into the weld pool during the welding process.
