Avoiding welding is certainly possible but the installation may take significantly more time and there is always the risk of things becoming loose in the future. If you can find a blacksmith that can follow instructions, he can do the difficult part for you. You will basically need him for installing the pillar-side joints and securing the leaf-side joints on the leafs - the rest you can do yourself.
The pillar-side joint is the pivot point for the one end of the operator and is fixed to the pillar or a side wall. It is crucial that the pivot point is placed at precise the distance from the axis of the hinges that the manufacturer specifies. Every operator comes with a metal piece you can use for this purpose but quite often you have to modify it (shorten it or extend it) and you also have to fix it firmly. Fixing it will probably require installing a metal base-plate (on which to secure it) on the side wall or welding supports to the side rails.
After you have done that, you extend the operator, almost to its full extend, and mark the point where the leaf-side joint rests on the closed leaf. You then weld the joint on the leaf or bolt it in place.
That, and possibly installing a closed position gate stop on the ground, where the leafs meet, is the difficult part of the installation.
The rest is laying cables, fixing the control board in place, fixing photocells etc, connecting everything and programming the automation.
