AI Thread Summary
Resistance or spot welding differs significantly from arc or TIG welding, as spot welding involves direct contact between electrodes and the workpieces, while arc and TIG welding create an arc through gas between the electrode and the workpieces. For joining two bolt rings of similar thickness but different outer diameters, one can utilize the step formed by the thickness difference to enhance the weld. TIG welding is suitable for seam welding along the inner circumference and can also be used for fillet welding at the inner corner of the step. Understanding the type of joint required is crucial for selecting the appropriate welding method. Proper planning and technique are essential for successful welds in this application.

TL;DR Summary
How do we do resistance ie. spot weld by use of arc/TIG welder
How do we correctly do resistance ie. spot weld by use of arc or TIG welder (if the difference is big explain each of this weld separately) to join piled up two bolt rings of the same thickness 2-2.5 mm and center diameters but largely different outer diameters
 
Physics news on Phys.org
One could take advantage of the different outer diameters and spot weld around the formed 2.5 mm step.

resistance ie. spot weld by use of arc or TIG welder
Resistance or spot welding is different from arc or TIG welding. Spot welding usually means having electrodes in contact with the surfaces of the work piece(s), while arc or TIG means an arc passes through a gas in a gap between the work piece(s) and welding electrode. In TIG, an inert gas is applied around the electrode.

What kind of joint is one planning? In other words, how does one plan to join the two rings. If one is joining the two rings along the seam, then one could use TIG welding to do a seam weld on the inner circumference and a fillet weld at the inner corner of the step.

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
