The safe way to onshore and offshore welding

Oil and gas pipelines

Quality first, from the field to consumers

Globally wanted. Locally owned. Dangerous and non-renewable. Inevitable part of our societies and our lives. Oil and gas it is.

Knowing is safety

Knowing the physical laws of oil and gas is a starting point. Knowing what and how to weld in different mechanical and environmental conditions is safety. Gas and oil fields and rigs, transmission and distribution pipelines, refineries – all with their own specialties to know and understand. And, in the end, it is safety that counts in the oil and gas business.

Lower rework costs

As materials are developed that possess greater strength, corrosion-resistance, and other enhanced-performance properties, welding of the materials grows more and more difficult. In demanding engineering projects, quality issues causing delays easily create costs that exceed the project profit.

Bigger filler material savings

Duplex and austenitic stainless steels, high strength steels, aluminum alloys. The selection of welded materials is vast. Knowing the optimized welding process for the application optimizes the welding costs.

Increased welding efficiency

All fabricators are seeking ways to improve their productivity, to get the product ready sooner, and at lower cost. Therefore, a shift from manual welding to some form of automated welding has been taking place in all industries for several years now.

Do you know your welds inside out?

There are ways to do that.

Keeping you on the safe side

Tested in the Atlantic Ocean, Arabian deserts and Siberian forests, Kemppi is the qualified partner for the most demanding oil and gas welding projects. Our customers excel by using our reliable equipment with optimized arc characteristics and multi-site welding management software with advanced documentation collection and management. The equipment and management software help you to meet the customer requirements and global standards, such as API, ASME, AWS, ISO and COST. Kemppi is the safe way to welding.

The quality of pipe welds correlates strongly with the productivity of pipeline projects. The demand for larger diameter pipes with higher strength steel is increasing. Need for thinner wall thickness and faster but reliable welding methods is obvious.

Kemppi has developed the most advanced root pass welding process in the world. The Kemppi WiseRoot+ process enables welding without backing, which saves backing material and labor time costs. It results in high class welds with easy control, and also decreases welding time that contributes largely to the project’s productivity.

Oil rigs

When operating in the middle of a stormy sea, the word “extreme” gets a whole new meaning. Completing a welding project at the oil rig demands extensive documentation and perfect, durable welds. Kemppi solutions offer 100 % traceability of every weld even in extreme conditions. The number of welding imperfections is minimized with Kemppi. Also, the probability of corrosion is reduced because of excellent welds and traceability. All these increase directly your productivity.


Kemppi has been the partner in many refinery building projects. Our intelligent equipment adjust your welding procedure according to the welded material and the pipe diameter, liquid influx/flow and pressure. For your welders, our training is an easy way to gain the needed knowledge and skills to do their jobs safely.
