When establishing a new production facility in Esbjerg, Welltec began utilizing WeldEye welding management software for more efficient welding quality management. As a result, Welltec was able to save time on preparing quality documentation and ensure top-notch welding quality for its products.

Welltec is a globally operating Danish company that develops and provides well technologies and solutions for the oil and gas industry. The company is dedicated to reducing environmental risks, fuel consumption and carbon footprints by producing safe and lightweight solutions based on clean technology.Welltec relies heavily on welding in its production stream. For example, one of its solutions, the Welltec Annular Barrier (WAB) is a steel construction that allows wells to be segmented for improved production. Their construction calls for multiple welded seams that must all endure the extreme conditions prevalent thousands of meters under the earth’s surface.

Main challenge

Oil and gas wells are probably the most demanding environment for metal structures. Vast temperature fluctuations, harsh chemicals, high velocity flow rates, and high mechanical loads set their requirements on production.

In 2014, Welltec was in the process of establishing a new factory in Esbjerg. As the company had decided to move from manufacturing prototypes to producing the actual sales items themselves, there was a need for monitoring the welding process to ensure the high quality of products and reduce the risk of costly defects.

Kemppi's solution

In order to fulfill the strict quality requirements of the welds, Kemppi provided Welltec with six MasterTig MLS 3000 machines. The TIG welding process was chosen due to its suitability for the most demanding welds, particularly stainless steels. As for quality control, Welltec began the implementation of WeldEye welding management software in monitoring the quality of its welding production. The software has given Welltec the means to verify the quality of each weld for the benefit of its customers' risk management.

In addition, WeldEye automates the collection of welding parameters for the necessary quality reporting of the heavily regulated oil and gas industry. In this respect, Welltec was now able to save valuable time on a task that was previously conducted manually. Pleased with the cooperation, Welltec perceives Kemppi as a quality partner that helps to ensure compliance with the high quality standards in Welltec's production.
