STUB WELDING

Manual Stub Welding

Automated Narrow groove stub welding

This kind of welding method was developed so that thicker joints can be welded more conveniently. This type of welding process has important advantages for the oil and gas industry, some of which are mentioned below.

  • It is convenient for welding thick materials.
  • There are very little angular distortions as the joint preparation is done almost parallel-sided.
  • It reduces the weld volume significantly compared to the traditional welding process.
  • Reduces the heat-affected zone.
  • Minimizes residual stresses and material distortion.

Manual Stub Welding

In this technique, the entire welding process is continuously monitored to ensure that only the purest weld is applied by using the GTAW process. It allows the welder to join large cross-sections without losing the tensile strength of the material in any significant form. This allows the weld strength to remain strong, which is very important in the oil and gas industry. To ensure the integrity of welding, the experts of Raysun Techno Industries LLC use a non-destructive and testing method that includes visual, radiographic testing, liquid penetrant testing, ultrasound testing as well as hardness inspection of the welded joints.
