The VDL KTI welding team

A team of qualified welding engineers and skilled welders who deliver best-quality welding with maximum efficiency. Our welders are qualified for various welding processes according to international standards.

We have experience in different welding techniques and more than 1600 welding procedures to accommodate every unique manufacturing situation and difficult welding positions.

Assembling

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.

Welding

Our experienced and highly-trained welders possess qualifications to weld all the desired materials using the following processes:

GTAW (Automatic)
SAW
GMAW
SMAW
PAW
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.

Orbital TIG welding

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

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.
