Due to the use of welded finned tubes in heat exchangers, gas blocks are characterized by very good electric energy production performance, and their reliability can reach 98%. Finned used exchangers usually welded. Such should be characterised following properties: high thermal resistance high-temperature corrosion a flue atmosphere, appropriate joint strength hardness. The most popular techno...

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...
