Welding is a process by which two pieces of metal or plastic are joined by melting with a significant heat source and a possible contribution of flux material that serves to facilitate this fusion . Welding is a process used since ancient times. Until the 19th century, the only way to weld metals was in forges, where blacksmiths managed to join metals by melting and beating them. It is from the end of the 19th century and beginning of the 20th century when the different types of welding that have survived to this day and which we describe below began to be developed. Electric welding In electric welding or electrowelding, an electric current is passed through metal electrodes that press on the pieces to be welded, making good contact so that the electric current circulates well. Thus, a strong amount of heat is generated at the welding point, which causes the elements to be welded to melt and join together. In this welding there is no input of material and it is one of the most used due to its simplicity.
Gas welding In gas welding, or autogenous welding as it is also known, two pieces of metal, which may be the same or different, are melted by providing a heat source from the combustion of a gas. When Cuba Email List the material used for combustion is a mixture of oxygen and acetylene, the welding process is known as oxyacetylene welding . This welding reaches a temperature of 3000ยบ C. Autogenous welding does not usually use external material input for fusion. It is a very useful method for melting non-ferrous materials such as copper and aluminum. For many years it was the method used to weld different types of materials, but currently, its use is in decline since it has been replaced by arc welding. banner_seas_welding_728x90_campus_seas electric arc welding Arc welding is a set of welding techniques whose common element is the use of electricity as a source of energy. You can use direct current or alternating current.
Using an electrode and the application of energy, an electric arc is created that melts the materials at the point where the welding is made. Another common characteristic that the different types of arc welding have is that they use an electrode, which can be consumable or non-consumable. And an inert gas, known as shielding gas, is usually applied in the welding area. Sometimes filler material is also used. Next, we explain the different types of arc welding that exist. Manual Metal Arc Welding or MMAW (Manual Metal Arc Welding) Steel electrodes with a coating are used. When heat is applied, the coating melts and allows the steel to come out from inside the electrode, which, when fusing with the base, causes the pieces to remain welded. MIG welding In MIG welding, the electrode is consumable and is what serves as a welding bead when it melts on the pieces to be welded. TIG welding A non-consumable electrode is used in TIG welding.
