Hi guys. I would like to know if there is a way. It would make it so easy! because I need to weld all the horizontal lines that composes the floor curve, as shown in the video.

Try _in ‘Parallel Projection’_ mode and in side (front or left or right or back) view. Then doing a _left \> right_ selection around the floor edges, leaving all other edges out. See if your selection is what you need by copying them to the side.  
If the selection in the copy is okay, weld the edges and move the welded selection back the same distance.
