How welding can be defined?
welding is a process which joins two dissimilar metals........ Actually it is more than that. Welding is a process that involves the application of heat to either add more material or join pcs. together. It is not used just for metals (dissimilar or not) but glass, plastics and more. The pcs. to be welded must melt in order for it to be called welding. Soldering, silver soldering, and brazing are comparable to glueing.
Which is the oldest type of welding?
When man started to melt and cast metal he would pour the molten metal into a mold, usually formed in the sand. If he wanted to join two or more of these "castings" he would place them close together and pour more molten metal where they touched. This would melt the edges of the two castings and upon cooling join them with weld. This is a basic welding process.
What is Thermofused?
Thermofusing is the joining of two pieces of metal by means of a thermic reaction - as opposed to welding them. A thermic reaction is so hot, that it melts the ends of the pieces of metal to be joined (it's commonly used to join lengths of rail track together). Welding only heats the welding rod - not the surfaces to be joined.
What is the purpose of the arc welding?
Welding is done to weld materials by operating a welding machine. Many industries such as Shipyard, Robotics will be needing welding applications. The applications include extending a rod eor pipe, joining two materials etc. My brother is doing a welding course at Weldtech Training Inc at Ontario. He is very much fond of welding. It gives someones great opportunities to work in several fields.
Is there types of electrodes in Shielded Metal Arc Welding?
Probably more than there are types of metal. There are many electrodes manufactured just for welding steel and for welding ON steel. Some electrodes are made to weld steel and other metals (multi-purpose). Some electrodes are designed to protect steel from chemicals and corrosive elements and are used to CLAD or OVERLAY or BUTTER. Steel, stainless steel and some other metals are manufactured with different alloys and electrodes are made to match these. Some electrodes are made to join dissimilar metals, say steel to stainless steel or Monel. It is very important to use the correct electrode for the application at hand.

What is thermite welding?
Thermite welding is a process that uses a chemical reaction to create intense heat to join two pieces of metal together. It involves a mixture of aluminum powder and metal oxide that, when ignited, produces temperatures high enough to melt the metal. This method is commonly used to join railroad tracks and other large metal structures.
What is a word meaning to join two pieces of metal by means of heat?
Welding is the process of joining two pieces of metal together by heating them to a high temperature and then fusing them together.
Can a threaded joint be welded?
yes ,we can weld this. welding is the process of joining two materials .we can join this by spot welding or by arc welding.
How do you join metal to metal?
Metal can be joined by welding, soldering, or using adhesives. Welding involves melting and fusing the metal together, while soldering uses a lower melting point filler material to join the metals. Adhesives provide a strong bond between the metal surfaces without the need for high heat.

What is a base metal in welding?
A base metal is also called the Parent metal. It is that metal in the welding practice that has been cut by the various forms of cutting, then prepared and is to be welded. Welding is performed to join one section of the base metal to another section of base metal by means of the various welding processes, e.g. SMAW(Shielded Metal Arc Welding) where welding welding rods are used, GTAW(Gas Tungsten Arc Welding) where Tig wire is used, FCAW(Flux Cored Arc Welding) etc. The welding rods, the TIG wires etc are called the filler metals, for they fill the weld gaps by depositing their molten-state weld metals.
How is oxygen used used in welding?
Oxygen is used in welding to increase the burn rate of the fuel gas, such as acetylene, in the oxy-fuel welding process. The oxygen reacts with the fuel gas, creating a high-temperature flame that is used to melt and join metal together. Additionally, oxygen is used in oxy-fuel cutting to aid in the combustion process, resulting in a clean cut through metal.
What is the difference between arc welding and resistance welding?
Arc welding uses an electric arc to melt and join metal pieces together, while resistance welding uses heat generated by the resistance to electric current flow between two metal pieces to join them together. Arc welding is more versatile and can be used for various types of metals, while resistance welding is more suited for high-speed production and is commonly used in automotive and appliance manufacturing.
What is msg welding?
MSG welding, or Metal-Solid-Gas welding, is a process that involves the use of a filler metal to join two metal pieces together. It typically employs a solid wire electrode and a shielding gas to protect the weld pool from atmospheric contamination. This method is commonly used in industrial applications for its efficiency and ability to produce strong, high-quality welds. MSG welding is often compared to other techniques like MIG and TIG welding, but it has its own specific applications and advantages.

Is mig welding a forge welding?
No, Forge welding is the simplest form of welding where two metals are heated to a state than can be forced to meld into each-other such as hammering or by other mechanical means such as a press. MIG Welding is short for Gas Metal Arc Welding (GMAW). This is a process which uses electricity to melt the parent metal and the electrode (wire) while shielded by a inert gas to keep contamination's (our atmosphere (aka air)) out of the weld puddle. Forge welding uses brute force and heat to join metals while MIG welding uses electricity and a shielding gas.
