Types of welding
Do you fear in welding? Don’t worry, it is nothing. It is the processof inter molecular bonding of two similar or dissimilar metals byheating and brings its melting point temperature, in this conditionthe external pressure may or may not be used, or third metal vizfiller rod may or may not be used. The heating is produced by electricarc, oxy-acetylene flame or oxy-hydrogen flame etc. where the metal’send portion to be weld. The basic requirement of welding is i) heatenergy, ii) cleaning the edge before the welding, iii) atmosphericcontamination, iv) weld metal properties, v) application of pressure.Heat: During welding it should required sufficient amount of heat forfusion. Otherwise the joint may produced incomplete fusion.Cleaning: Cleaning the welding edges should be properly maintained.Because the unwanted materials are may be damaged the welding joints.The unwanted materials are- oxides, nitrides, oil, grease, dirt, sandetc. These should be properly cleaned by either mechanically orchemically.Atmospheric contamination: The main atmospheric contamination isnitrogen, oxygen and humidity. During welding flux, various inert gasor other types of gas should be used, which may helps to avoid thereaction with these contamination.Welding metal properties: It is very important for obtaining thecleanness weld joint. These processes are which can be controlled withsuccessfully- i) de-oxidizers used during welding, ii) to mixing upthe alloy in filler rod, iii) by the controlling of base metalcomposition, iv) by the post weld heat treatment.Application of pressure: In few welding process the sufficient amountof pressure is required for weld joint. This pressure may be obtainedfrom mechanically, pneumatically or hydraulically.Advantages of welding: a) Similar or dissimilar metals can be joining.b) The joint can produce same or more strength than base metals. c)The welding machine portability is the good advantage for anywherewelding. d) The welding can easily performed in very big size likestructure under budget. e) The welding is the only one process whichcan make joint the broken parts easily. f) It has extra facility thatthe joint can performed under water.Disadvantages of welding: a) Highly trained persons are required forgood welding. b) Initially investment cost is very high. c) Duringwelding the metallic structure of base metal may be changed for hightemperature. d) Often heat treatment may require after weldingprocess. e) In welding the edge preparation should required, so morethan one man power is required. f) The welding equipments handlingrequired with carefully. g) The welder should have sufficientknowledge about general electric. h) The very dangerous ultravioletray and fumes are produced, so safety should be taken properly.Classification of welding: There are different types of weldingprocess are classified into two main groups. One is fusion and anotheris pressure welding. The fusion welding are sub-classified in gaswelding, thermit welding, metal arc welding, carbon arc welding,atomic hydrogen welding, TIG welding, MIG welding. The pressurewelding are forge welding, spot welding, seam welding, butt welding,flash welding.The general condition of welding: The welding joint will be easy ifthe weld joint portion is cleaned by wire brush or machining or sandblasting. By these processes the unwanted materials or impurity iscleaned properly. If these impurity presences in weld pull then it maybe weakened the joint by inclusion. So the quality joint is cannot bemade. The oxidation rate is directly proportional to temperature. Mostwelding process performed in high temperature and that time theoxidation acting as a weakening agent in weld metal. This is preventedby the using of fluxes and makes a strong weld joint. In manualwelding process the flux is covered on the electrode. This flux ismelted in high temperature and covered on the weld metal. Then itcreates an artificial anti oxidation gaseous covered on weld metal.Powder type flux is used in gas and forged welding. In other weldingprocess there are used non oxidation gaseous components like Argon,Helium etc. which covered on the weld metal and prevent the oxidation.Industrial application of welding: Today the welding process is veryeasy because the machines are much modernized. So the weld joint canbe performed in any position. It has very much application in workshopto fabricate the small/big structure, repair and maintenance ofvarious components. In fabrication work there various type angle,channel or beam is used to make a structure. There may be used the nutbolt to join together, but it is less strong than welding. Thestructure can be made by casting. But this process is very expensive.In other way the welding process is less expensive, labor cost andeasy. Due to this causes the welding is very popular in fabricationindustry.

Link or content described: tumblr analytics There are many different types of welding process in the welding history. The term welding, whose origin is identical with that of the word well in the sense of welling or boiling up. In the previous time known to have been familiar to some extent with the blowpipe or 
Link: flame torch, but there was no record of their having ever applied it to the joining of metal by fusion process. The water-gas welding process was applied in the end of 19th century. The flame which is produced from water-gas replaced the blacksmith s hearth as a mean of heating the metal and welded the metal but this is first welding. Another type of welding is the more modern types the termed cast-welding. In this method the molten metal pouring into a mould which has runner at the point where the casting had failed to flow or wherever there was a fractured place. The molten iron poured in until it was fluid everywhere around the edge of the job and runner was stopped up, then the iron was allowed to cold in the mould. This welding process can be said modern Link: fusion weld process, but this is slightly high cost process than other types of welding. At that time the Link: oxy-acetylene welding process discovering was the most vital importance invention in the welding history. That awardable invention gone to Mr. Edmund Davy in 1836. This type of welding discovery was known to chemists a long time before it became a factor of economic importance to the world. Willson and Moisson had developed a method of making calcium carbide(CaC2) in the year of 1891. In 1895 a Frenchman had discovered the another type of welding process that equal parts of acetylene and oxygen burned together gave a higher temperature. Another welding had been happening in 1881 by Mr. de Meritens. During his experimental works he faced with the necessity of joining together certain parts of electrical storage batteries. He placed the work-piece on a table and it connected with the positive pole of the source of current , the other pole connected a carbon rod which has kept on operator hand. Then he strike on the work, at that time first produced a arc and some heat was generated. Finally he made a fused the metallic lead of battery plate. The first job lead container which was used for some chemical container was produced with this type of Link: arc welding process. Elihu Thomson had made first electric welding machine patent in the year of 1886, which was big type of welding machine. His process was usually called Link: butt-joint welding . He had also modify the other welding system later because the jaw which was used for griping the job the piece got too much hot. So he developed water cooled jaw system. Short history of welding There are various types of welding process described in this page. Just follow these and learn it wisely. The terms welding is define the joining of two or more surface (usually metals, but not always) under the influence of heat, so the product shall be nearly homogeneous union as possible. This is the main definition of welding. What is welding?
Technical Background of welding: In all Link: welding joint processes heat is applied to or produced at the joint and heated surfaces are brought into close contact --, as result the joint surfaces to grow together into single body. Now we will see what happen during this growing up together process. It is we all known that the matter is made of molecules which in turn into atom. The atoms of molecules are become active when the temperature of material reaches absolute zero (-2730C). At that time the molecules are moves with vibratory motion. In the higher temperature the vibratory motions of atoms is greater. During welding temperature it is sufficient to allow the atoms to make a bridge for the closely contact --ing surfaces. Thus there is an exchange of atoms among the molecules of the surfaces to be joined. Through this exchange of molecules of one surface interlock with adjacent other surface and this process we get Link: weld joint .
