Medium and High Tensile Steel
ULTRATHERME-M
AWS: SFA 5.5 E 11018 M
EN ISO CODE: 18275-B E7618-N4M2 A H5
- Basic coated hydrogen control electrode with a stable and smooth arc that is easy to strike and restrike.
- Low spatter and good bead finish.
- Welds are of radiographic quality.
- The weld metal displays good crack resistance and produces sound weld metal possessing excellent strength combined with good impact properties at subzero temperature.
It is ideally suited for welding high strength Q & T steels like WEL-TEN 80, SA 517 grades and their equivalents. The electrodes are ideally suited for welding restrained joints in high strength steels.
