Types of welding 1Plastic Welding In Plastic welding or pressure welding the pieces of metal to be joined are heated to plastic state and then forced together by external pressure. Few types are run by simple machines while others need expensive equipment. Fusion Welding In fusion welding or non pressure welding the material at the joint is heated to molten state and allowed to solidify.
As different inert gases argon helium are there the types of metals that it is compatible with are also vast. Machine welding can be defined as mechanized welding with equipment that performs the operation under the continuous supervision of an operator. The following are the different types of welding.
We expect now you have a basic understanding of the various types of welding. There are currently over 50 different types of welding processes. Welding seam welding spot welding lap joint welding etc.
Further based on the welding process the welding machines types used for welding operation in industries are. MIG welding is one of the easier types of welding for beginners to learn. Types of welding machines pdf This article throws light upon the top five types of spot-welding machine.
Low Pressure Welding Torch. Two Types of Welding Fusion Welding melting base metals Arc Welding AW heating with electric arc Resistance welding RW heating with resistance to an electrical current Oxyfuel Welding OFW heating with a mixture of oxygen and acetylene oxyfuel gas Other fusion welding electron beam welding and. The external reactor type 3.
