Automatic welding is an efficient and precise welding technology widely utilized in industrial applications.Depending on the welding process,there are several automatic welding methods,each with its commonly employed fields.
Gas Shielded Welding
Gas shielded welding,also known as Metal Inert Gas(MIG)welding or CO2 welding,is a common automatic welding method.In gas shielded welding,the welding arc is formed in the weld joint,while inert gas or mixed gas is used to prevent the weld from being contaminated by harmful elements like oxygen and nitrogen in the surrounding air.Gas shielded welding finds extensive use in steel structures,automotive manufacturing,shipbuilding,and rail transportation.
Arc Welding
Arc welding,also referred to as manual arc welding,is one of the earliest and most common welding methods.However,full automation of arc welding is achieved through welding robots.Arc welding employs a metal rod called an electrode,which melts and fuses with the base material during the welding process.Arc welding is commonly used in the fabrication of bridges,pressure vessels,petrochemical equipment,and other heavy-duty structures.
Laser Welding
Laser welding is a high-energy focused welding technique that utilizes a laser beam to generate high temperatures,fusing metal components together.Laser welding offers advantages such as high precision,small heat-affected zones,and rapid welding speeds.It is extensively applied in electronics,aerospace,microelectronics devices,and precision instrument manufacturing.
Electron Beam Welding
Electron beam welding is a method that uses the kinetic energy of high-speed electrons to melt and weld metals.Electron beam welding is characterized by deep weld penetration,minimal heat-affected zones,and high welding speeds.It is commonly employed in high-end manufacturing fields like aerospace,defense industries,and space exploration.
Plasma Arc Welding
Plasma arc welding involves ionizing gas to create a plasma arc,which is then used for welding.This method is suitable for materials with good electrical conductivity,such as stainless steel,aluminum alloys,and copper alloys.Plasma arc welding finds
