SUMMARY

This discussion focuses on the techniques for performing resistance or spot welding using arc or TIG welders to join two bolt rings with a thickness of 2-2.5 mm. It clarifies that spot welding involves electrodes contacting the workpieces, while arc and TIG welding utilize an arc through a gas gap. For effective joining, TIG welding is recommended for seam welding along the inner circumference and fillet welding at the inner corner of the step, taking advantage of the differing outer diameters of the rings.

PREREQUISITES
  • Understanding of resistance welding techniques
  • Knowledge of arc welding principles
  • Familiarity with TIG welding processes
  • Experience with welding materials of varying diameters
NEXT STEPS
  • Research the differences between resistance welding and arc welding
  • Learn about TIG welding settings for different material thicknesses
  • Explore techniques for effective seam and fillet welding
  • Investigate the use of inert gases in TIG welding
USEFUL FOR

This discussion is beneficial for welders, metal fabricators, and engineers looking to enhance their skills in resistance and TIG welding techniques for joining metal components effectively.

TL;DR
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.
