Electro-Slag Welding (ESW) of Steels

Electro-slag welding is a primary method for cast weld assemblies of heavy sections since one of the key characteristics is its suitably high deposition rate.
Some key advantages include a single pass process, weld symmetry, high welding speed, simple joint preparation and low flux composition. Continue reading

Electro-Slag Welding (ESW) of Titanium Alloys: Part Two

Due to its well-known superior strength to weight ratios, titanium has become a more and more critical material choice in aerospace applications which require heavy loading.
Due to titanium’s high chemical activity welding can be a real challenge but to overcome this, new technologies are being developed which uses the slag pool and argon to shield the weld site from interstitial element contamination. Continue reading
