Flash Butt Welding

About video :- Flash Butt Welding
Flash butt welding is a type of resistance welding that joins components by creating heat through resistance, melting the metal at the joint, and then forcing the molten metal together under pressure. It's often used for thick workpieces like rails, pipes, and chains.
All About Flash Butt Welding: Applications, Advantages, and ...
Here's a more detailed explanation:
How it works:
1. Preheating:
The ends of the workpieces are preheated by moving them back and forth while a current passes through them.
2. Flashing:
The workpieces are slowly brought together, creating a brief contact that generates a high current density and rapid heating, causing the metal to melt and "flash" out.
3. Forcing:
The molten metal is then forced together under pressure, creating a solid weld.
4. Burn-off:
During the flashing process, any impurities or oxides are burned away, ensuring a clean weld.
Key features:
High speed:
Flash butt welding is a relatively fast process, especially when compared to other welding methods like arc welding.
High quality welds:
It can produce strong, reliable welds, particularly for thick sections.
Automated process:
Most flash butt welding machines are automated or semi-automated, which helps to ensure consistent weld quality.
Applications:
Common applications include joining railway rails, welding pipes, and manufacturing wheel rims.
Mobile vs. Stationary:
Stationary:
These machines are typically used for larger projects or when a fixed location is available.
Mobile:
Mobile flash butt welding machines can be transported to the job site, allowing for on-site welding of structures like pipelines or rails.

1.impact damage near the weld
2.Chance of fire hazards is high
In flash welding, metal is lost during welding
Aur kuch ho to aapp hi bata digiye❤

App jo funny aur easy terms me batate ho wo asani se yaad ho jata hai kaash sare teacher aisa karte

Flash butt welding ek effective technique hai, lekin iske kuch bade nuksan bhi hain jo ignore nahi kiye ja sakte. Sabse pehle toh iski initial setup cost kaafi zyada hoti hai, jo chhoti industries ke liye problem create karti hai. Doosra, ye sirf specific shapes aur sizes ke liye hi kaam karta hai — complex ya uneven joints ke liye suitable nahi hai. Aur teesra, thin materials ko weld karna isse risky hota hai, kyunki overheating ya burn-through ho sakta hai. Isliye har condition mein iska use possible nahi hota.

Sir huge fan🙏🙏🙏🙏
Can you pls make a full video on furnaces, its types and industrial adopted types for the job

[DiprajMandal-]

Sir please prepare a video about Red Mercury 😊

[NARAYANSINGHCHADANA]

Par bill ke kharche ka parcha kitna aayega 😂

Requirement of high voltage electric
Aur
Maybe it isn't for sustainable for complex shape

[novitameena]

There is no current in outside environment

[thats_me_ved]

Jyada electricity lagti hai jo normally available nahi hoti

[ToobrosGAMING]

2 alag alag metal ke lia succesful nahi ha 🤔

[Shshi]

Heavy machinery is used for this welding, it is not portable...

सर ऐसी कौन सी कमी होती है जो शक्तियों के गलत इस्तेमाल न होने के लिए बनी होती है, हां यह प्रकृति की चीजों में तो होता है मगर मानव निर्मित चीज में उल्टी बात लग रही है

[digitalteknik]

Kya Kami Hai hamen to maloom hi nahin chalo aap Hi Bata dijiye

[robintomar]

लेकिन धारा का प्रवाह तो कडी के दूसरी तरफ से होगा .
फिर जिस स्थान पर जोड लगाना हैं वहां spark कैसे होगा?

[TNI.]

Sari baten chhodiye Sar pahle yah bataiye yah Roj Roj nai shayari kahan se late Hain😂😂

[MohitKumar-gded]

High current but low voltage difference

[Itachi-mzbg]

In Water welding krne jao to machliyo ki ek puri generation hi saaf ho jayega 😂😂

[bhadoria]

Mercury metal mein weld nahi kar sakta 😂😂😂😂

[TheIGGamear]

Jismein Karan nahin jata usmein welding nahin hoga Karan bhi jyada lagta hai
