Dear Sir,
My question is when exactly squeeze time start.
1.Either it is start when switch padel pressed by operator
2.Or as first contact occur b/w electrode & metal piece for welding

[@mechanicalnexus]

I need to go and see the book. I do not remember it now

[@team_9838]

Sir spot is a solid state welding

[@MTpenchi]

Sir ek video spot wellding tarans farmar ko kese banae kitni no. Wire use kre ditel me bataiye

[@muzammil7688]

[@redelala7652]

Nice. But can you show how to calculate 15kva and primary and secondary wire for spot welding

[@mechanicalnexus]

When I will do any mathematical parts than only I can show.

[@sagarlokhande9396]

Hello sir,
Can we perform spot welding on sheets of unequal thickness.?? & If yes what must be it's optimum Thickness Ratio.
Also Can we make spot welding on aluminium sheets.
Kindly explain...

[@mechanicalnexus]

Yes Unequal sheet can also welded together by spot weld. Thickness ratio I am not sure but it should be less than 3-4mm.
Spot welding is suitable for Low carbon steel but Aluminum sheet also can be weld but required high current as compare to low CS.

How to measure the dent?
We can simply measure the nugget dia with vernier callipers.

[@mechanicalnexus]

I am not much sure about dent measurements but I know some laser based camera or ultrasonic medium used to form the image of dent.
But yes if you have height and dia you can simply calculate it. 😊

Sir agar electrode main hum cupper ke badle brass Use karain to yee work karega kya?

[@mechanicalnexus]

Copper is good conductor than brass. Kaam to karega but current pass krne mai dikkat krega.. Resistant k karan jada heat develop hogi..

Sir Classifications of welding me apne autogenous (solid state) welding me resistance welding aata hai or ushi ka ek part hai spot welding hai .....but sir apne abhi btaya ki liquid state welding me aata hai spot welding ???🤔🤔🤔 May be kuch wrong hai।।। Baki sir ek number sikha rhe hai app mere 50% dought clear ho gye hai or remenig 50% baki ki video dekh kr ho jaye gi ।।।।।

[@mechanicalnexus]

As per book enhone classification mai welding ko solid state mai rakha hai but actually resistant welding is fusion welding type. Esly detail mai maine fusion welding rakha hai...
