Welding is one of the most important processes used in manufacturing and industrial construction. Inductance can play a key role in producing effective and consistent welds. In fact, it has been estimated that the use of inductance in welding can improve weld quality by up to 20%.
In this article, we’ll take a closer look at what inductance is and how it contributes to better welding outcomes. We’ll also discuss how inductance is measured and how welding operators can control inductance in order to make the strongest, most durable welds.
By the end of this article, you’ll understand the fundamental principles of inductance in welding and be able to identify which welding processes and conditions require different levels of controlled inductance.
What is Inductance in Welding?
Inductance in welding is the ability of a welding machine to respond and adjust to the welding current. It smooths out the weld current and results in even, consistent welding.It is especially important in high-powered welding since the current can oscillate a lot. Inductance is measured in henries and is one of the components on the welding machine.
What are the Benefits of Inductance?
Inductance in welding has several advantages:- It helps to minimize the effect of electrical noise on the weld.
- It helps to protect the welding machine from sudden increases in current.
- It can help to improve the quality of the weld by providing a more even arc.
- It helps to reduce weld time by providing a more consistent arc.
How Does Inductance Work?
Inductance works by storing energy in an electromagnetic field and then releasing it when the current changes.This process helps to smooth out the welding current and prevents sudden changes in current. The amount of inductance that is needed depends on the welding process. With some processes, a greater amount of inductance can result in better quality welds.
For other processes, a lower amount of inductance is preferred. It is important to know the appropriate amount for each welding process.
