Welding the stand won't help get the bike on the stand. It will help getting the bike off the stand, which when fully loaded for touring is very difficult if your stand is crapped out. (/7)
What will help getting the bike on the stand are pivots in good order, technique, and a mechanism designed to work properly, for human strength.
A stand that does not lift the bike very much will be easy to use on a hard surface. The same stand will be useless on uneven ground or soft surfaces.
Try getting a loaded bike off a 'good' centre stand in soft ground.....it's difficult.
I think a c/stand has to be tailored to suit the individual rider.
