6.1.2 Welding
                                 to the face plates of injected steel sandwich panels can be carried
                                 out, provided that any effect of heat input on the elastomer does
                                 not affect the capacity of the panel. The design documentation submitted
                                 in accordance with Ch  1,  7.1 General is to
                                 include details of how the effects of heat input will be addressed.
                                 
                              
                              
                              
                            
                           
                           
                           
                              
                              
                              6.1.3 If pre-fabricated
                                 panels are to be employed, welding to the face plates can be carried
                                 out, provided that any effect of heat input on the elastomer does
                                 not affect the capacity of the panel. The design documentation submitted
                                 in accordance with Ch  1,  6.1 Plans to be submitted 6.1.6 is
                                 to include details of how the effects of heat input will be addressed.

                                 attachments, cable trays, and small pipe clamps etc. can be welded
                                 directly to the top or bottom plate without the use of internal reinforcing
                                 plates. Any defects in the structure resulting from the removal of
                                 temporary attachments are to be repaired.
