What is post weld heat treatment?
post weld heat treatment is done on the weld areas after welding, to remove the residual stress present in the welded part formed during the welding process, it prevents to cause brittle fracture in a metal
Post weld heat treatment for aws D1.1?
AWS D1.1; 5.8 "Stress-Relief Heat Treatment"
Which steels are used in heat treatment and its components?
stainless steel
What does the term annealing mean?
It's heat treatment. By heating and cooling a metal under very controlled circumstances the properties of the metal can be improved.
How do you weld a bevel broken gear?
You don't. You will never keep the tooth profiles right and will screw up the heat treatment. Get another gear!
What is the definition of 'critical thickness'?
The thickness at which insulation begins to decrease heat loss is described as Critical Thickness
How heat affects the hair during conditioning treatment?
How heat affects the hair when conditioning
What is critical heat flux and what is its physical significance?
critical heat flux is the heat flux at critical point
What is the physical basis for existence of a critical insulation radius?
The general thinking is that with the increase in thickness of insulation around the system(say a pipe) the heat loss will always reduce.This is true only up to a certain radius of the insulation called the critical insulation radius.After this radius any increase in the thickness would in fact increase the heat loss.This happens because there are two phenomena taking place here viz. conduction and convection.Conductive resistance is dx/k i.e. thickness/conductivity with increase in thickness the conductive resistance increases hence heat loss decreases.Convective resistance is 1/hA,now beyond the critical radius the increase in conductive resistance is offset by the reduction in convective resistance.This is because with increasing radius one has also achieved a greater heat transfer area as A=2*pi*r*l.
What is the term given to the Sudden cooling of metal during heat treatment process?
quenching
When was Heat Treatment created?
Heat Treatment was created in 1976.
What is the importance of hydrogen bond in DNA in terms of their integrity during heat treatment?
Hydrogens bond number in the DNA structure shows any importance in terms of their integrity during the heat treatment.Justify.
What is post weld heat treatment?
post weld heat treatment is done on the weld areas after welding, to remove the residual stress present in the welded part formed during the welding process, it prevents to cause brittle fracture in a metal
How is the best way to reduce the thickness of your ice?
Put it in heat.
What is cryogenic heat treatment?
cryogenic metal treatment
How does glass thickness effect heat loss throughout a house?
the thicker the glass the less heat goes in
When heat is added or subtracted is called?
heat treatment
