I have a chance to buy some d.o.m. tubing cheaper than elec. weld and I was wandering witch one would be the better choice, and is it harder to work with?

DOM by far is about 1/3 stronger than electric weld and you can go thinner and maintain strength to a comparable thicker electric weld.

D.O.M. cheaper??? If it is the right size and wall thickness, you have a great deal on your hands. D.O.M. is stronger and better by far.

Here you go GrnHOrn-
Typically the DOM will have a brownish cast to it, with no weld seem showing. The ERW(electron resistance welding) tubing will have a weld seem down it and have a shiny-gray color. The DOM typically about 25% stronger depending on what alloys you are comparing. The DOM gets its superb mechanical properties (strength) from the forming process. You'll pay 30-50% more for it too.

D O M=Drawn Over Mandrel. Perfectly round every time, wheras electric weld is rolled and welded leaving imperfections. Buy as much as you can afford if your buying it for less than ERW. My 2 cents
