Welding Electrodes
Weld Metal
Classification & Coading: IS 814:2004 : ER 4211X, AWS 5.1 : E6013
Approvals: BUREAU VERITAS, BUREAU OF INDIAN STANDARDS (ISI MARKED), INDIAN BOILERS REGULATION-1950 (IBR), LLOYD’S & SHIPPING (LR), LONDON, NATIONAL TEST HOUSE (NTH)
DESCRIPTION
WELD METAL is a medium – Heavy & Rutile coated, general purpose mild steel welding electrodes, specially manufactured for RADIOGRAPHIC quality weld, low spatter, adequate penetration, Easy slag removal (self pealing slag), and finely rippled smooth beads are the special feature of weld metal electrodes. Mechanical properties are very good and consistent. Easy to operates on AC as well as on DC welding power source in all conventional welding position.
APPLICATIONS
Railway Wagons, Boilers, Fire Boxes, Auto Bodies, Ship building, Structural works, Machine Base & Machinery, Construction, Pipe Lines, Storage Tanks, Bridges, Building Construction Works and mild steel furniture etc.
