Factors to Consider When Purchasing Filler Material
The filler material you choose for your welding procedure can make or break your weld. It is imperative to choose a material that possesses the right chemical and mechanical properties. Additionally, the filler material should also be capable of withstanding the weather conditions that the weld will encounter. This helps in minimizing the risk of developing any defects in the weld or the risk of cracking or corrosion. Procuring the right filler from Welding Electrodes Suppliers will ensure that you wouldn’t have to spend extra time and effort in reworking the whole thing.
How to Select the right filler material?
There are certain factors that you need
to consider when selecting your filler material. The right material will help
you in creating a premium quality durable weld. You can talk to some of the Welding Electrodes Suppliers in India to figure out the right filler
material as well. However, if you are not comfortable with talking to suppliers
directly then the following list might be helpful:
The Base Material
A weld is essentially the process of joining together two different materials and as you can imagine the chemical composition of the two materials plays an important role. Usually, when the chemical properties match, the physical properties also tend to be similar, for example, the yield and tensile strength. Thus, the final strength of your weld will depend largely on the strength of the base material. However, there are times when the materials joined are not of the same strength. In such cases, the strength of the filler material should match the lower strength of the base material.
The Position of the Weld
If possible, welders should try to rotate the part that is being welded so that it is in a flat position. This is the most economical position followed by the vertical or horizontal position and lastly the overhead position. Of course, if the position cannot be changed at all then the welder will have to weld in various positions. This can be quite challenging especially if only one wire size available. Changing the welding positions can compromise the overall efficiency of the process. Hence, purchasing the filler material from the Welding Electrodes Manufacturers in India that allows for versatility is advisable.
Shielding Gas
Another important thing to consider is the shielding gas and whether it is compatible with the filler metal you are going to use. Different shielding gases tend to have different effects on the filler metal. For instance, adding argon to carbon dioxide permits the welder to transfer much of the filler metal’s chemistry into the weld. This helps in reducing the level of spatter and in providing premium quality of the weld. However, if one is not careful enough then the risk of cracking increases as well.
