The primary objective of the existing work is
to evaluate hot gas welding technique for PP composite
material and carrying out analysis over the critical
parameters (air flow rate, temperature, weld time) to
determine material weld strength in tensile conditions.
Polypropylene blend with elastomer have wide
application in engineering areas due to their desired
properties but due to these changed properties over
existing one recycling get affected and became difficult
so their reparability should be considered. Hot gas
welding helps to join the cracks and restore defects in it.
Extracting the optimized values from critical
parameters will help to make the method more efficient
and effective. Tensile probing carried over specimen by
considering ASTM standards assist to know former and
later tensile conditions of welded joints.
