ser + MAG Hybrid Welding of Various Joints

Mag Welding Process - Analysis of Welding Parameter Influence on Joint Geometry

Quality of welded joint at MAG welding process depends of numbers of influences, like type and thickness of base metal, groove type, welding position etc., but the proper selection of welding parameters is also very important. Due to that, the analysis of weld bead geometry at MAG welding process with regard to weld current, voltage and weld speed (heat input) and the type and shielding gas flo...

Development Technology for Welding in Mig-mag Shielding Gas Environment

The information system is a coherently structured assembly, made of electronic computing and communication equipments, software, processes, automated and manual procedures, used as automatic data processing tool within a field of activity. In the process of welding in shielding gas environment with fusible electrode, there are used either inert or active gases. Therefore, we make the distinctio...

Hybrid Laser-Arc Welding

Laser Beam Welding of Austenitic-Ferritic Transition Joints

Transition joints between austenitic stainless steels and ferritic low alloy steels are extensively utilized in many high-temperature applications in energy conversion systems. Problems related to the use of such dissimilar metal welds (DMWs) have long been recognized, because of premature failures often occurring during service, connected to thermal stresses generated at the weld interface and...

Structure Improvement of Aluminothermic Welding Joints by Using Modifiers

Aluminothermic rail welding was from the beginning a great success because its low price even in 1895 in Germany. This method is now, widely used all over the world for the railways construction, maintenance and modernization. Instructions give you guidelines for preparing papers for conferences or journals. After 1989, the welding needs of the potentials beneficiaries (Romanian Railways, Urban...
