| The panels to be welded must be fitted before the application
of the seam. |
| The bonding areas must be free from adhesive remains in the
welding areas and free from dust and sealing paste. |
| The customary application of zinc based electroconductive
paint is not necessary. |
| With the displacement of the adhesive, the welding flange
is covered with adhesive, thus ensuring anti-corrosive protection. |
