what welder is better

There are 2 reasons to build your own trailer:
1. You have plenty of time and ability and the materials are mostly free. (and you want to justify a new welder)
2. You have plenty of time and ability and you want to make a custom trailer. (and you want to justify a new welder)

Otherwise a mass-produced trailer is generally cheaper than the the retail parts to build one.

You said it! If your goal is to learn metal working and you are using a trailer project to learn on, go for it. If not, it would be more economical to buy one. I have all the welding and cutting equipment already, and I didnt even consider building any of my trailers.

If the goal is to learn metal working, then he shouldn't be using a trailer project to learn on, unless he's only going to use it in a private non-critical environment and not on public highways.

The main thing for him to do would be not to choose something critical to fabricate/weld on where a faulty weld or workmanship might endanger peoples lives. :thumbsup:

I weld structure steel with stick 6013 and follow up the welds with a 1-1/4X torch flame to 'normalize' the weld area. Strong as heck and vibration resistant.
I learned to normalize in Aviation Airframe welding in the 80's. Have welded solid big block engine mounts in drag race cars that way.

I'll have to try that "Normalizing" trick. It sounds a whole lot easier than an angle grinder to improve the look of a weld.

Any tips on how to do it?
