Help butt welding frame for coffee cart - 30x30x3mm RHS
Hi All,
I am very much a novice welder but love getting my hands dirty.
- I am making a coffee cart that utilises 30x30x3mm painted RHS as the frame.
- The cart will be 1200w x 700m D x 900m H
- It will be skinned in Plywood
- It will have castor wheels
- I will be using Gasless MIG for the process.
- 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.
