Tube Welder Using GTAW

In order to understand the advantages of using an orbital tube welder, it is important to understand how the machine operates. In order to do this, it is necessary to research some of the more technical aspect of the process.

The orbital welding process uses the Gas Tungsten ARC Welding process (GTAW), as the source of the electric arc that melts the base material and forms the weld. In this process, an electric arc is established between the Tungsten electrode and the part to be welded.

For any tube welder, this is the typical way to weld a pipe. The tube welder can start this process when the machine uses a voltage signal to begin the breakdown of the insulating properties of the shield gas and make it electronically conductive in order to pass through a tiny amount of the current.

A capacitor is used to dump the current into this electrical path. This reduces the arc voltage to a level where the power supply can supply a current for the arc. The power supply then provides a consistent current in order to provide a consistent weld on the arc. This helps create an intense heat that will be used to fuse the arc and metal together.

The material selected for welding varies depending on the environment and applications. The standards typically accounted for in this process are the mechanical, thermal, stability, and corrosion resistance requirements of the application.

For complex application, it is necessary to have a prolonged testing period in order to determine if a material is suitable. Some materials contain additives that make it easier to weld. Some of these materials require post welding treatment, so it is important to select the right material for an efficient, long lasting job.

Any minor changes to amperage may affect the welding job. Any minor deviations in the elements could make a vast difference in the process, so it is important to account for any variations. A different consistency of sulfur could significantly alter the weld profile. Because of this, attention to detail is vital to the overall success of a job.

If you account for any deviations, then there should not be many issues when performing the weld. Overall, this has proven to be a relatively efficient process. Tube welders have enjoyed the success they have found by using orbital tube welding equipment, so maybe it is an option for your business.
