Every team is different, but my team has avoided having any welding on our robot at all. The reason being that should a weld break, we are (pretty much) guaranteed to not be able to fix it in the pit. We also have a sponsor that provides us with bolts for each year, as well as another sponsor that helps us with fabricated parts (usually laser cut and bent if needed), making a sheet metal chassis held together with gussets and bolts what we have found is the best option for us given our resources. We have also done drivetrains in the past made primarily from 1x2 aluminum, also held together with gussets and bolts.
