I just know nothing as because my college was closed due to corona till now it is closed I knew nothing about welding , I am mechanical student, after seeing this lectures I knew much better than before You are great sir for your great explanation Just a big Thank you sir🙏🙏🙏🙏
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
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...
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.
Sir arc welding me hum DC AND AC DONO KA USE KARTE THE PAR ISME SIRF AC HI KYU YADI CURRUNT CONTROL KARNE KE LIYE TO CURRENT KO CONTROLL KYU KARNA HOTA HAI
@@hindi2451 ek formula hai V=IR (ohms law)... yha current change krne se hi voltage and resistance par farak dikh jayga... Esly sabka apna apna use hai..limit mai
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 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 ।।।।।
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...
Not sure but gun ko wo handle se pakadta hai aur handle proper insulator se cover hota hai... Insulator jese ki PLAS wala.. live wire cut kar dega but apke hath ko current nhi lagne dega same there

Sir tarnfarmar kese banaye uska puri ditel ke sath video banao
Sir ek video spot wellding tarans farmar ko kese banae kitni no. Wire use kre ditel me bataiye
agar video milai tu mujha bhi bata dena bhai.
Can you share friction welding
Sir you are great
Thankew 😊
Thanku sir
मेरा प्रश्न यह है कि दोनो इलेक्ट्रोड की बीच की दूरी कितनी होती हैं
Kis conditions mai puch rhe hai
Thanks you so much sir
You are welcome 😊
Nice. But can you show how to calculate 15kva and primary and secondary wire for spot welding
When I will do any mathematical parts than only I can show.
Is there a control circuit?
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
I need to go and see the book. I do not remember it now
Hiii sir
Spatring ka problem kyu aata h? PLZ REPLY
I m facing big problems
My component is ss 304 material
Hi, spatter issue kafi reason se hota hai. Apka mat stailless stell hai to mai aisr nhi bata sakta ki kya reason ho sakta hai..
Please tell us about is failure mode causes for defects like spot burr, dents, pin holes, spot puncture etc.
I need to check it for this case

Dear sir Aap ek Armature welding machine ke program ki puri jankari ki video dale
Hi, Sorry programming ki knowledge nhi hai merko
dear
we need to know difference between step don transformers and SCR technology using in spot welding technology
Sir pawer press clutch plate ke bare me video banoo
I will try... ok
👍👍👍👍👍👍👍
Voltage kaise kam Karen

Current ki intensity se kafi chijo par farak padta hai

How to measure the dent?
We can simply measure the nugget dia with vernier callipers.
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. 😊
السلام عليكم كيف حالك شكرا لك على الرغم اني فهمت 20% من الذي تكلمته لكن مجهود عظيم تشكر عليه
ارجو ان تفعل ميزة الترجمة اخي
Sorry, Unable to get it.
Good explanation sir. Sir can provide voltage and current for each thik of sheet and how to know weldability
Not much know about practical experience... Only subjective knowledge I have
@@mechanicalnexus sir what should be nugget or electrode dia?? And how to calculate weldability
@@jayprakashyadav3714 Nugget diameter is 6xSquare Root of " t ".
Try to watch resistance welding for more clarity of your question.
Sir ji Thora nickel ke bare me batana
Jarur... Material science k lecture mai add karunga Nikel
Sir can u do nimi based syllabus destructive test, post heating, preheating etc
Soon i will uploadon welding Destructive and Non Destructive test video

यदि हमें स्पॉट weilding को कंट्रोल करना हो तो केसे करेंगे । Thyrastor और वेल्डिंग टाइमर तथा circuit diagram ke bare me समझाइए sir
Sir electric arc furnace pe bhi video bna dye mere exam h 3 December ko
Etnna jaldi possible nhi h dost
Sir agar electrode main hum cupper ke badle brass Use karain to yee work karega kya?
Copper is good conductor than brass. Kaam to karega but current pass krne mai dikkat krega.. Resistant k karan jada heat develop hogi..
Sir tig welding me hose pipe green kyu hota hai
Hello Sir, very good piece of information. I have a query, whether tin plating quality on CRCA sheet impacts weld strength
Sir
Spot welding machine transfomer primary winting tune
👍
😇🙏
Why do we use step down and not step up
V2/R se to wo bhi same power dega na
Rapid process nahee hoota current taiz nahee hoti to kia karian.
32,35,40,50,100 gauge spot welding machine transformer kaise banate
Sorry No idea about transformer. Electrical engineer can help you
Water under hai gun ke under to short nhi lagega sir
I never heard to use water in welding for gun.
Arc welding as use spot welding
Arc welding m/ c and spot welding m/c transformer same principle ?
No.. both are different welding
Very nice
Thank You 😊
Fain
this is same as resistance welding
Sir sem class notes milega kya apka
Notes to nhi h... Apko video dekhkar banana hoga
Kay ham 1.5 mm ss sheet ko spot welding kar सकते hai
Books and theory ke according possible hai...Aur Jada detail ke liye apko manufacturer se contact karna padega...
Sir namaste transformer data bataia
Namaste ji... Data kis chij ka
Hold time kya hota hai
Welding opertion perform krne mai use hota hai ye time
Why used 3 current in spot welding
upsetter machine?
Sir why does hole become in spot welding of carbon steel
Which hole?
Spot welding is solid state welding/liquid state welding..?????
Book mai solid state mentioned hai.
Yeh machine single faz me aata he kya
3 phase
Why copper is difficult to weld using spot welding?
Due to heat conduction nature
Thank you🙏.
My pleasure 😊
😍😍💞
🙏😊
How many kva machine would be suitable to spot weld 3mm metal wires. Please answer, I want to buy one but dosent have any experience
Need to check manufacturing instructions and guidance
Departmental je ka exam dena hai sir jee welding ka mcq bataye
I will make a video on welding Mcq soon. 👍

Sir operator ko shock kyu nai milta jab ki wo resistance welding gun operate krta he ?
Not sure but gun ko wo handle se pakadta hai aur handle proper insulator se cover hota hai... Insulator jese ki PLAS wala.. live wire cut kar dega but apke hath ko current nhi lagne dega same there
@@mechanicalnexus actually ye que mujhe interview me kiya tha or maine jo apne bataya vaise hi return ans kiya but satisfied nahi tha un ke liye
@@sagarahire5835 ohh.. To machine se current ko earth kiya gya hoga
Spot welding non fusion welding hi sir
Sir resistance welding to solid state welding h
Actual mai resistance welding fusion welding(Liquid State Welding) hai but book mai esko solid welding ki category mai likha hua hai
Sir spot welding ka spot na a to keya karna hooga
Try again
Resistance spot welding is solid state welding
Liquid state welding
hi sir
Hello
Sir eska pdf nahi milega
Pdf to nhi hai dost eska
4v to 12v how it decreases 🥺
Using step down transformer.. 😊
But 4v to 12 v it's increased
Spot welding is not a fusion welding it's all about pressure welding
@jagadeeshchepala4953 if there joint due to melt, its fusion welding.
Sir contact no. Milega muje notes chahiye Mera exam hai
Channel decription mai link hai waha se contact kr skte ho telegram par
Thank u sir
You are welcome
Thank you sirji
Welcome Ji 😊
