Hi All,

I am very much a novice welder but love getting my hands dirty.



  1. I am making a coffee cart that utilises 30x30x3mm painted RHS as the frame.
  2. The cart will be 1200w x 700m D x 900m H
  3. It will be skinned in Plywood
  4. It will have castor wheels
  5. I will be using Gasless MIG for the process.
  6. I have cut the RHS for Butt joints.



I am wondering how to best weld the joints where the curve on the edge of the tube is. I am thinking it will be a multiple pass process. Put the first weld into the bottom of the joint then run a second pass over the top. Or is it ok just to use the first pass?

I have looked around for examples but they are hard to find. Is there a particular name for the joint that I should be searching for - that might help me find more info.
