again :
to perform a neat weld on a bench in comfort is one thing that can be learned in short time ,given some expert is available and you got some mechanical empathy...
welding a spaceframe includes a lot of off position welding ..thats where the amateurs and the experts quickly separate.
the welds of that aluminium manifold ..gosh ... that guy has surely done thousands
of hours of aluminium welds.. and his equipment has not seen anything steel and he would kill you using one single piece of his kit to work on ferrous products..
but ,coming back to the topic ..you obviously have to make decisions in the design process and as long as you don´t have a expert welder in your team it does not make any sense to start designing beautiful metal fabrications ,you have no clue of :how to design -as you have no expertise on the best layout practise to get to the desired result or have to aquire skills that will claim a lot of time as the weld quality is a product of experience =hours ...not a very efficient decision..imo.
don´t get me wrong ..I have my own TIG welding equipment and have done a lot of this stuff ..and had to learn to just not fall in that sort of trap - to badly want to do something -and pay the price for it ..wasting a lot of time needed somewhere else.. my name is not Andersson ,though.
