Description and Applications

For welding of ships, bridges, and steel frames.  Good slag detachability; X-ray, crack resistance, weld ability, and beautiful beading can be obtained.

 

Guideline in Usage

1. For welding of ships, bridges, and steel frames. Good slag detachability; X-ray, crack resistance, weld ability, and beautiful beading can be obtained.
2. When using recycled flux, it’s better to use the recycled flux mixed with newly made flux to avoid appearance and shape change of the bead.
