Airbag failure

Hello, good I have a failure in the companion airbag in the painting. And looked at the cables below the seat and it seems that one of the pretensioners is canceled because the 2 cables that come from it are together, I weld the cables but it remains the same. I need to send me photos of the cables of the companion seat that is of the sidewalk of 2, to see if the mine are correctly. Thank you
