BUMAX DX 129 for ultrasonic welding
stirring of the furnace ’ s liquid bath and can be customized to match the needs of different EAF process steps .
Polysoude welding solutions
Schunk Sonosystems has decided to use BUMAX DX 129 screws for all its ultrasonic welding flexure sonotrode products to further improve quality and reliability . The machines are mainly used in the automobile industry . BUMAX DX 129 ( duplex stainless steel ) offers very high tensile strengths of min . 1,200 MPa and excellent fatigue resistance properties . It deals successfully with the extreme forces during the ultrasonic welding process , such as 20,000 vibrations per second . The high fatigue strength that BUMAX screws offer is crucial to their ability to withstand a high number of cycles without fracture . All BUMAX bolts are made with the highest quality European steel , and its advanced manufacturing processes result in the further enhancement of the material ’ s fatigue resistance properties . The high-quality raw materials BUMAX uses guarantee excellent fatigue strength . BUMAX also uses rolled threads rather than cut threads , which further increases fatigue resistance .
Tenova revamps its EAF for ORI Martin
Polysoude offers an extensive product range to cater to the diverse joining needs . Closed orbital welding heads are utilised for autogenous welding of small tubes with thin walls , guaranteeing exceptional precision . Open orbital welding heads are designed for pipes with larger diameters and thicker walls , enabling multi-layer welding with the addition of filler wire . The company ' s innovative Hot Wire TIG welding and Narrow Gap TIG welding technologies enhance productivity . Furthermore , Polysoude has developed orbital welding heads specifically for the assembly of heat exchangers , enabling seamless joining of tubes to tubesheets . Polysoude has ventured into new territory to meet the demanding requirements of cleanroom operations , particularly in the semiconductor manufacturing sector . The company ensures that all components used in the gas supply system , such as tubes , valves , flanges , and tees , are joined , manufactured and packed in a cleanroom . The welds produced during manufacturing and installation must be flawlessly smooth , without any defects or heat tinting . Polysoude ' s closed welding heads of the UHP type ( Ultra High Purity ) have been designed to prioritise welding quality and suitability for cleanroom purposes . These models are air-cooled and can weld tube diameters ranging from 1 / 4 " to 1 ".
ORI Martin has awarded Tenova a new contract to replace its Electric Arc Furnace ( EAF ) at its mill in Brescia ( Italy ). The revamping of ORI Martin ’ s EAF highlights the group ’ s ongoing commitment to evolve and innovate in its pursuit of a sustainable steel sector . With this contract , ORI Martin will finalise the revamping of their plant , optimising consumption and process for the safe production of steel with minimal environmental impact . The Brescia plant will also be ready for the installation of an Electro- Magnetic Stirrer with Tenova ’ s Consteerrer ® process which will increase process efficiency . The Consteerrer ® technology is an innovative electro-magnetic stirring system , developed through an exclusive worldwide partnership with ABB . It offers significantly low operating costs , extremely reliable and safe operations , as well as superior quality steel . The Consteerrer ® enhances the Consteel ® Evolution process with ABB ’ s ArcSave ® non-contact electromagnetic
WF 25i Dual
With the touch of a button , welders can switch to another filler metal or wire diameter thanks to the Fronius WF 25i Dual . The dual wirefeeder is the perfect partner for the Fronius TPS / i or the Fronius iWave and can supply each process line with gas separately . It is available for both 450 mm and 300 mm wire spools and delivers flexibility with a variety of options for mounting and operation . The carefully thought-out operating concept behind the WF 25i Dual enables welders to switch the process line , filler wire , and associated parameters in a number of ways . The WF 25i Dual can be mounted on a cart , crane , Trabant , or boom so there is always enough space to reach difficult-to-access areas in complex welding environments . The complete system , which consists of a TPS / i or iWave , the WF 25i Dual , and two welding torches , is a clever combination both from a cost perspective and an environmental point of view .
