That was not meant as a comment on your welding skills, just mine.
I believe your post mentioned a 1 ton chain fall. For a few hundred pounds on a track supported every couple of feet, many concerns go away. My rolling bridge crane uses wide beams with HF trolleys and it works extremely well. When I was designing it, I figured I would use it once a month. But I find that I use it constantly.
You might consider a lube like boelube or even paraffin. Both are available as solids so you could run a line of lube before you start cutting. I use paraffin on my horizontal band saw when cutting thin wall tubings and it works reasonably well. It certainly makes a big difference. There is no reason not to help the blade out if it is easy and not messy.

Sorry, I only meant that I trust my welds,
