Welding requirement
No parts shall be let unwelded unless clearly tsated on the
drawing, for efficient and easy access it is recommended that sharp
edges (that are not to be welded) are rounded to minimum R2.5
before assembling parts.
Finishing requirement
To ensure sufficient adhession for surface treatment all sarp edges
shall be rounded to minimum R2.5, welding spatter beads and slag
shall be completely removed, damaging in surfaces shall be filed and grinded flush, negative
thickness measurements are prohibited.
Techinical parameters:
Test temperature and charpy V-notch impact energy shall be in
accoradance with DNV lifting appliances No.2.22. values for plates
in primary and essential welded steel structure is listed in table
below:
| Yield stress Re(MPa) | Thichness(mm) | temp(°C) | Impact energy(J) |
| 355 | 6< t ≤ 25 | 0 | 34 |
| 25< t ≤ 50 | -20 | 34 |
| 50< t ≤ 70-40 | -40 | 41 |
| 70< t ≤ 150 | -40 | 50 |
| 690 | 6< t ≤ 25 | 0 | 46 |
| 6< t ≤ 25 | -20 | 46 |
