Welding
Hi friends,
Ever wondered about solid state welding?
Well there are in principle three types of solid state weldings:
1.DIFFUSION WELDING:
In this process,the two surfaces are made to come in intimate contact of each other.Later a good amount of pressure is applied on them.It sometimes take hours to get the two surfaces welded.
Also heating is not required in it.However if we apply heat,the matter of time can be cut to minutes.
By this process we can join metal-metal,ceramic-metal, metal-metal with intermediate layer of other materials etc.
(Next time ask a Gold smith what is the actual process.😁)
2.ULTRASONIC WELDING:
This technique joins similar or dissimilar metals by high frequency vibratory energy.May be about 20000-60000 Hz.
The advantage includes we don't require any flux material for welding.
The parts to be joined are clamped together and then high frequency energy is transmitted in it.
We can weld to a thickness of 0.38mm to 2.5mm.
3.FRICTION WELDING:
To surfaces which have high relative velocity are made to slide against each other.
So that due to high friction a large amount of heat is generated.And ultimately the surface material melts and joins with each other.
Advantage is that the heat affected region is very small and dissimilar metals can be easily joined.
e.g;mild steel tool shanks are fastened to high speed steel tool shanks.
