How to weld bolt to sheet metal.
An angle grinder fitted with an abrasive metal cutting disc works well to cut all kinds of metal including bolts angle iron rebar and even sheet metal.
Proper technique will come with practice and experience.
As the stick material melts in the heat the flux coating also melts creating both a gas and a liquid slag which act to shield the weld from oxidation.
Also it will ensure that you don t get any warping of the materials you are working on and no burn through as well.
Forget the larger 1 8 inch tungsten electrode and use a smaller one.

Resistance welding of galvanized steel is however more of a problem than arc welding.
In order to weld sheet metal or patch panel you have to follow certain rules and use specific techniques.
But the discs wear down quickly cut slowly and shrink in diameter as you use them.
When galvanized sheet is resistance welded the welding heat causes less disturbance of the zinc coating than the arc processes.
The welder check to make sure that the valve to the shielding gas is open and that you have around 20ft 3 hr flowing through the regulator.
Stick welding uses a metal filler rod or stick coated with flux.
This method is often used for auto body repair but would be a great first option for a stripped screw hole in sheet metal.
Instead we recommend using a diamond blade that s rated to cut ferrous metal.
3 ways to attach metal to metal without welding.
To weld sheet metal with solid wires use electrode positive ep or reverse polarity.
Using plumbers tape around the screw threads jb weld or again a larger screw.
