uSky Transport pays special attention to quality of work performed on Test Track 4. Since most of our structures are made of metal, we often do welding works. They require experience, technical expertise and adherence to safety standards. That is why, upon completion of a particular stage of work, we conduct a mandatory quality control.
Welding tests are procedures that are carried out to evaluate quality of welded joints and ensure their compliance with standards and requirements. These tests are usually carried out at production stage or during quality control after welding is completed.
The main purpose of welding tests is to ensure reliability and safety of welded units and joints. Such tests allow to determine how well the welded joint is made, and to identify possible defects or shortcomings in it.
The essential purpose of welded joint tensile testing is to check basic strength characteristics such as yield strength, elongation per unit strength, weld hardness, etc. Also at this stage, quality of the welded joint is assessed for pores, blowholes, cracks, and lack of penetration. This kind of check allows you to evaluate quality of weld both for compliance with regulatory documents and for welder competence.
In the attached report, one can observe such parameter as yield strength, which is here equal to 734 MPa. In this case, yield strength of base metal is 690 MPa, which confirms required strength of welded joint. The cross section and actual hardness values of weld indicate quality of work in accordance with EN and AWS standards.
