In summary: If the rings are being joined at the outer edge, then spot welding is more appropriate.In summary, it is important to consider the type of joint when determining the best method for resistance or spot welding, whether using arc or TIG welder. TIG welding involves an arc passing through a gas while spot welding uses electrodes in contact with the surfaces. For joining two bolt rings with different outer diameters, spot welding along the seam is recommended for outer edge joining and TIG welding is recommended for inner step joining.

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

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.

1. What is spot welding and how does it work?

Spot welding is a type of resistance welding where two or more metal sheets are joined together by applying heat and pressure to a small area using electrical current. This causes the metal to melt and fuse together, forming a strong bond.

2. What are the advantages of using an arc/TIG welder for spot welding?

An arc/TIG welder offers precise control over the welding process, allowing for consistent and strong spot welds. It also allows for welding in hard to reach areas and can be used on a variety of metals, making it a versatile option for spot welding.

3. What materials can be spot welded using an arc/TIG welder?

An arc/TIG welder can be used to spot weld a variety of metals, including steel, stainless steel, aluminum, and copper. It is important to use the appropriate welding settings and electrodes for each type of metal to achieve a strong bond.

4. What safety precautions should be taken when spot welding with an arc/TIG welder?

When using an arc/TIG welder for spot welding, it is important to wear appropriate protective gear, such as welding gloves, a welding helmet, and a welding apron. Additionally, make sure to work in a well-ventilated area to avoid inhaling fumes from the welding process.

5. What are some common mistakes to avoid when spot welding with an arc/TIG welder?

Some common mistakes to avoid when spot welding with an arc/TIG welder include using the wrong welding settings for the type of metal being welded, not properly cleaning the metal surfaces before welding, and not applying enough pressure during the welding process. It is important to follow proper welding techniques and to practice before attempting important welding projects.
