In the pressure welding technique, the use of heat is lesser as compared to other welding techniques. The pressure is used to make suitable joints. The use of pressure lessens the use of heat. The temperature to be used can be below the melting point of the metal. This technique is called solid-state welding. If the temperature to be used is above the melting point then the technique is referred as fusion state welding. To improve the quality of weld, the two metals must be properly cleaned. Any impurity can cause obstruction in the welding process.
Industrial usage of the process of welding:
- On an industrial scale, cold pressure welding is usually used for combining sheets and wires that are made up of metals.
- Explosive welding is used when the components to be combined are made up of different materials.
- Friction welding can be used both for the same and different type of materials.
It is to be kept in mind that there is not a single welding process that can be used for all purposes. You must adopt specific techniques to obtain the best results. Thus, proper knowledge about the types and applications of welding is required. Always use the proper equipment to carry out the welding process successfully. Compact joints are produced by the use of argon welding machine [ตู้ เชื่อม อาร์กอน, which is the term in Thai].
Fusion welding is the most used type of welding:
Although pressure welding is being used in many places, but the use of fusion welding is much higher. There are many types of fusion welding. This is the benefit of fusion welding, and it allows the industrialists to get the right type of welding according to their requirements. Safety is an important factor that should not be neglected here. The process of welding involves the use of high heat that can melt metals. This heat can cause damage to humans. We must use the proper safety equipment such as gloves and welding glasses [แว่นตา เชื่อม, which is the term in Thai]
