Leirinav Lda has several years of experience in the welding field in the Offshore Industries.

Because of that experience Leirinav Lda identifieddiploma is not enough for welders to achieve good results under difficult circumstances.

Effective training in simulated
practical environments is therefore an absolute must.
For that reason Leirinav Lda created QWS (Quality Welding School).

After completing a course, the welder will have expanded his or her field of expertise, and more specifically, expanded it to the level which is demanded by- and customary in, the Offshore and Heavy Construction industries

Quality Welding School

Practice proves that merely training welders to obtain an officially recognized diploma is not enough for them to achieve good results under difficult circumstances. Effective training in simulated
practical environments is therefore an absolute must.
QWS Leirinav provides additional training courses in the arts of SMAW,and FCAW welding and the gouging of carbon based metals
At the end of the courses each participant undergoes a welding test under the supervision of Lloyds Register. If the test is successful under the strict
current code specifications, Lloyds can use the laboratory test report to make out a final certificate. After completing a course, the welder will have expanded his or her field of expertise, and more specifically, expanded it to the level which is demanded by- and customary in, the Offshore and Heavy Construction industries
