Taiwan-Plasma: Plasma Welding: Principle of Operation, Features and Advantages


Posted December 24, 2021 by Taiwanplasma

Nowadays, plasma welding is one of the most popular metal joining methods. For achieving the required temperature, plasma works as the primary source of energy.

 
For making metal structures of the product durable and of high quality, welding is used to connect essential parts of steel. This technology has been utilized for many years since its inception, different varieties have appeared that allow you to work with different types of metal.

Plasma welding using a plasma machine is a popular choice used by many experienced welders. It works on the principle of melting alloys by a narrowly directed plasma jet, which is filled with tremendous energy. This technology is used to join different grades of stainless steel, refractory and various non-ferrous metals, as well as products made from different materials. However still, before commencing welding work, it is essential first to consider its important features.

The essence of plasma welding

Plasma metal welding works on argon-arc technology. The main advantage of the technology lies in the characteristics of the arc. Contrary to an electric arc, plasma has the form of a compressed plasma jet, which comprises powerful energy.

To understand the essence of plasma welding, you first need to consider what plasma is and the conditions for its occurrence. Plasma represents the state of gas when it is partially or entirely ionized. This suggests that it can be based not only on neutral molecules and atoms but also on electrons and ions, which come with a specific electric charge, comprising completely charged particles.

For converting gas into a plasma state, it is necessary to ionize most of its molecules and atoms. To reach this state, it is required to apply to the electron, which is the basis of the atom, an effort exceeding its binding energy with the nucleus, helps it break away from it. This is the essence of plasma welding.

Features and characteristics of the process

To understand the essence of plasma welding, it is worth considering its important features, especially how the process is performed using an automatic plasma machine. During the welding process, a very high temperature is applied in the welding area, which is created when the arc section is forcibly reduced and its power indicators increase.

This process results in plasma jet welding, at which temperature can easily reach 300000C. However, with argon-arc welding, they can only reach 5000-70000ะก. The arc acquires a cylindrical shape during the welding process, which allows you to maintain the same power indicator along the entire length.

During the plasma welding process, a high arc pressure is observed on the surface of the metal elements being welded. This makes it possible to join almost all types of metals and alloys.
