Should Spring Seats be Welded to Trailer Axle

Question:

In your last answer to “what happens if you don’t weld the spring seats #TRSS300 to the axles #8327834” I would like you to clarify your answer. I am not a mechanic so could you please explain in detail what you mean by “Axle might turn in the spring seats.” Also, what is the consequence to having the axle turning in the spring seats? Is this dangerous?

If they weren't welded it's very likely the axle might turn in the spring seat. You really only have to tack weld them in one spot to prevent this for a double eye suspension setup. If the trailer had slipper springs you'd have to have them fully welded.

Trailer axles have a bit of a bow to them which once you put the weight of the trailer on them they flatten out and you get the correct angle for the wheels tires. If the axle turns the alignment is going to be ruined and you'll most likely go through tires quickly and have other bizarre behavior too.
