To ensure that your welds look uniform and are of high quality, you must practice the technique of purging your pipe joint before welding. Because the inert gas weld purging process can be complex, you may have to go through some trial and error until you find the best way that works for you. Whether you’re still new or a seasoned pro, take a look at the reasons why you should be practicing purging your pipe joint for higher-quality work.
Protection From Oxidization
One of the main reasons why a welder will use this process is because it removes oxygen from the weld and prevents corrosion from happening. Introducing oxygen while welding will encourage the metal to corrode, weakening the weld you just performed. Purging the pipe beforehand will remove any excess oxygen and minimize the risk of corrosion while creating the project.
Clean Joints
If you did not purge your pipes before welding, the joint you are creating would not come out as cleanly. There might be discoloration or gunk on the seams because you did not carefully remove oxygen or clean your workstation. When these joints are dirty, they will not last as long or be as durable as they will when you use the inert gas purging from the beginning.
Stronger Weld Joints
Skipping the purging process can make your weld joints soft and weak. Removing the oxygen does not affect the integrity of the weld and instead strengthens the joint for the utmost sturdiness. Ignoring the process of removing the oxygen will leave the weld soft and vulnerable to potential damage or corrosion in the future.
Saves Time
Skipping the purging step in the process might seem like you are saving yourself time. In reality, you are taking more time to complete the project, as it likely won’t be right on the first try. To avoid frustration with your weld after you complete it, you should purge your pipes beforehand. Otherwise, you’ll spend that time trying to fix the damage that you just created.
Do not take any shortcuts when welding; purging may take more time to start, but the joint in your weld will be of top quality. Consider different techniques and practices to continue your education in creating quality welds. Take your time—you cannot improve your skills without trying new techniques.
