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.


Arc welding is a type of welding using electricity to heat and fuse metal together. In order to control the process the heat must be controlled by varying the current. MIG (Metal Inert Gas) welding uses an inert cast to protect the weld from the air at extreme temperatures during the welding process.

One type of welding is tube welding. Another type if mig welding.


Arc 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.


You can do Shielded Metal Arc Welding (stick) with an appropriate electrode. If the machine has a high frequency arc stabilizer then you can also TIG (tungsten inert gas) weld aluminum. Wire feed processes require a DC machine

Welding Electrorodes or Welding Rods are used in arc welding. Arc welding is a special type of welding which uses a welding power supply to create an electric arc between the base material (e.g. steel) and the electrode. The Welding Ectrorodes can be used for all weldable aluminum and mild steel.


pipeline welding You could find them from many welding institutes round the world. check the websites.


The Type of welding you are doing, the brightness of the arc.


Fusion welding includes processes that depends upon 'melting' to join similar materials (having same composition and melting points). Resistance welding is one of the type of fusion welding.


Welding is a skill that will open doors for many in the employment world. Attending a general welding school will help get a foot in the door of a successful career. There are trade and vocational schools that will offer welding programs. The school should be certified and the graduate will receive a certificate when the courses have been completed properly. Since there are several different types of welding, the welding school should be able to offer courses in all of the types. The future welder may need to learn more than one type to get the job that is desired. Some welders will do more than one type of welding at a particular job. Electric arc welding is the basic welding process. Even though technology has advanced greatly, this type of welding has never been replaced as the first process in structural welding. The electric arc welding is suited for exterior welding work. Each student will be certified in electric arc welding. Any job that requires interior welding will use a semi-automatic MIG welding process. This type of welding is always used in any manufacturing industries especially when mass production is being done. By taking the electric arc welding and the MIG welding, the student will be qualified to be employed as an entry-level welder in the manufacturing world. Another type of welding that may be offered at the school is heli-arc TIG welding. The TIG welding requires a higher skill level. Precision is the key in the TIG process, and welders who are certified to do this method will earn the highest wages. To be employed as a TIG welder, there needs to be a high skill level on stainless steel, mild steel, aluminum and other light materials. Blueprint reading is a large part of this course since TIG welding requires nothing but precise accuracy. The oldest welding method and one that is still being taught is the oxy-acetylene gas welding process. This process has been used at home as well as on the job. Since this process does both cutting and also brazing of mild steels, it is the most versatile. Many welders will choose to attend school to learn the basic welding, and then go back for the more advanced types later on.


How much time is required to complete education in welding depends on the type of welding education you are seeking. The American Welding Society webpage is a great place to get answers, and for Canadians, the Canadian Welding Society.


2 basic types, Gas shielding, and flux shielding. Gas shielding comes from compressed tanks of inert gas such as argon. these gases are pumped through the welding hose and over the weld pool. The flux type protects the weld by covering it in a layer of slag that prevent it from being contaminated by the surrounding air.
