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. |
