TYPICAL APPLICATIONS
• For radiographic quality welding of highly stressed joints in steel structures, heavy-duty boilers and pressure vessels, railway wagons, coaches and trailers etc.
• Also for maintenance welding / surfacing of cast steel / fine grained / heat treated steel and
wrought steel.
• Excellent for welding of higher carbon and higher sulphur steel which are susceptible to hydrogen induced cracking.
• Recommended for welding steels of unknown compositio
