HEAT
TREATMENT:
Hardness, Tensile, Yield, Elongation, Breaking
load etc. are tested after giving proper heat
treatment. Quenching, Tempering, Hardening and
Normalizing are done to get the desired results
as per customer’s requirement………….
Application:
Heat Treatment is a group of manufacturing
techniques used to alter the hardness and
toughness of a material. The most common
application is metallurgical. Heat treatments
are also used in the manufacture of forgings,
castings and other materials.
Technique:
The techniques include annealing, case
hardening, tempering and quenching
Heat Treatment of Weld Joints:
Heat Treating realigns the molecular structure
of a weld producing a more homogenous weld and
heat affected zone. Preheating weld metals
assists complete fusion during the welding
process and reduces porosity as well as the
potential for cracking. Post heating of a weld
is utilized to improve machinability. It also
provides corrosion resistance and reduces
brittleness. Twin Ports Testing utilizes
portable heat treating equipment to provide
services such as stress relieving during
welding, shrink fitting, preheating for heavy
welding projects, and preheating of high
strength steal that is prone to cracking.
Equipments Required:
The Heat Treatment sections are equipped with
electrically heated furnaces with advanced
temperature controllers and recorders for a
range of heat treatments from solutionising and
ageing to hardening and tempering, besides
annealing and normalizing.
Testing:
Hardness, Tensile, Yield, Elongation, Breaking
load etc. are tested after giving proper heat
treatment. |
