Preparation and cutting of steel
Cutting and beveling of materials shall be carried out by thermal
cutting or machining.
Thermally cut edges shall be ground to sound metal before welding.
All sharp edges, corners and Curing Zone must be rounded to
R=2.5mm.
Stainless steel shall by ground, and then acid treated and cleaned
before use.
Welding requirement
Welding spatter, beads and slag should be completely removed.
Surface damage is filled and grinded flush.
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 |
