Minimal distortion
Minimal distortion is a critical aspect of PT welding and fabrication, particularly when working with thin metals. Distortion occurs when the heat from the welding process causes the metal to expand and contract, which can lead to warping and buckling. Excessive distortion can compromise the structural integrity of the weldment and make it difficult to achieve the desired fit and finish.
PT welding and fabrication minimizes distortion by using a focused heat source and a non-consumable tungsten electrode. The concentrated heat input allows for precise control over the welding process, reducing the amount of heat that is transferred to the surrounding metal. Additionally, the use of an inert gas shielding environment helps to prevent oxidation and contamination of the weld pool, which can further contribute to distortion.
The ability to minimize distortion is essential for PT welding and fabrication in a variety of applications, including:
- Aerospace: PT welding is used to weld aircraft components, such as wings and fuselages. In this application, minimal distortion is critical for maintaining the aerodynamic shape and structural integrity of the aircraft.

| Non-consumable tungsten electrode | Allows for precise control over the welding process, further reducing distortion. |
| Inert gas shielding environment | Prevents oxidation and contamination of the weld pool, which can contribute to distortion. |
No spatter
In the context of PT welding and fabrication, “no spatter” refers to the absence of small droplets of molten metal that are ejected from the weld pool during the welding process. Spatter can be a problem in other welding processes, such as MIG welding and stick welding, but it is virtually eliminated in PT welding and fabrication.
The absence of spatter in PT welding and fabrication is due to the use of a non-consumable tungsten electrode and an inert gas shielding environment. The tungsten electrode does not melt during the welding process, so there is no molten metal to be ejected from the weld pool. The inert gas shielding environment prevents oxygen and other contaminants from entering the weld pool, which further reduces the likelihood of spatter.
The absence of spatter is an important advantage of PT welding and fabrication. It eliminates the need for post-weld cleanup, which can save time and money. It also improves the quality of the weld, as spatter can weaken the weld joint and create potential points of failure.
Real-life examples
Here are some real-life examples of where the absence of spatter is important for PT welding and fabrication:
- Aerospace industry: PT welding is used to weld aircraft components, such as wings and fuselages. In this application, the absence of spatter is critical for ensuring the safety and reliability of the aircraft.
