Qualified welders are critical for successful quality welding, but skilled fitters are equally important. Fitters are certified technical workers who shape and join pieces of steel, aluminum and other materials using heat generated by torches or lasers.
In our production process, each step has great impact on other steps. After raw materials are cut or machined into the correct shape and size, fitters are responsible for :
- Reading the detailed engineering drawings
- Marking the weld locations
- Fitting all the separate metal pieces together
- Tacking them in place in preparation for the welders to complete the job
This assembly requires good attention to details and high precision for measuring, even in millimeters. If the fitting is done well, it’d greatly help welders to finish welding with high quality and accuracy.
Our experienced and highly-trained welders possess qualifications to weld all the desired materials using the following processes:
- GTAW (Automatic)
- Overlay welding SAW and ESW
As a result of large numbers of skilled positioners and manipulators, we guarantee high quality of welding and maximum efficiency, which in turn saves your time and money.

VDL KTI uses orbital TIG welding primarily to weld tubes to tubesheets in heat exchangers. For certain unique manufacturing situations and difficult welding positions, it's often very challenging to achieve the highest standards of quality using manual welding. That’s why orbital welding is a great solution.
Orbital welding is a computer-controlled process using a welding head that can rotate mechanically through 360°. With our skilled welders’ precise operation, the result is consistent and higher quality welding, more efficient and productive processes, and eventually shorter lead times.
Electroslag welding (ESW) is a highly productive process which VDL KTI uses frequently for weld overlay, a cost-effective way that provides corrosion/erosion protection to the base material to meet the client’s specifications, codes and standards.
