Welding Electrodes: Look For These Features

Category: Academics

 

Welding is a fabrication process that is used for fusing metal parts. Usually, welding is used for thermoplastics and metals only. The importance of a good weld is simple and cannot be understated. It largely determines the strength of the structure. Hence, it is imperative to create a flawless weld. However, the most essential aspect of creating a successful weld is the kind of welding rod you use. The welding rod known as the welding electrode is easily available from welding electrodes suppliers.

How to Choose the Right Welding Electrode?

These electrodes are the medium that is used for fusing two different metals. Different types of welding rods can be availed from Welding Electrodes Manufacturers in India. They are available in different types and sizes, and their utility depends entirely on the machinery you will be using to create the weld. To create a perfect weld, it is crucial to choose the right electrode before you start welding process.

There are essentially three kinds of welding electrodes that are manufactured by welding electrodes manufacturers and they are as follows:

1. Covered Rods

2. Bare Welding Rods

3. Tubular

The following are some factors that you can take into consideration when selecting your welding rod:

1. Properties of the Base Metal

The chemical and physical properties of your base metals should match or at least closely resemble the properties of the electrode for your weld to be successful. You can refer to a metal composition and an electrode chart for this purpose. This will make your task of selection much more convenient.

2. Tensile Strength

Other than matching the compositions of the base metal and the electrode, you also need to match the metal’s tensile strength and compare it with the minimum value of the electrode’s tensile strength. This will help you avoid any cracks or other kinds of damage to the weld during the process. If cracks appear in the weld, you will have to redo the entire process. However, you’ll first have to clean up the cracked weld and restart. Thus, not matching the tensile strength can prolong the process. The first two numbers of the AWS classification define the tensile strength of the electrode.

3. Welding Current

Most electrodes come with the specification of the kind of power sources they can be used with. This means that they can either be used with DC or AC current. Some electrodes can be used with both types of current. If you need to deeply penetrate the metal, you can go for electrodes that can be used with AC currents. These electrodes also create a soft arc and even clean metal sheets can be welded by using them.

Conclusion:

Apart from these, you need to determine the thickness of the base metal and the welding position you will be using. These factors will also influence the kind of welding electrode you should procure from Welding Electrodes Suppliers in India. All of these considerations will help you in creating the perfect desired weld.
