1. The document analyzes the effects of different parameters on friction stir welding of polypropylene plates, including tool pin profile, rotational speed, and welding speed.
2. Microstructural images and hardness tests were used to evaluate the quality of the welds under different conditions.
3. The results showed that a threaded pin profile with rotational speed of 2250 rpm and welding speed of 40-50 mm/min produced welds with the fewest defects in the polypropylene material.
Friction welding is a solid-state welding process that generates heat through controlled friction between components. As the components are pressed together and their surface layers intertwine, a weld is formed without melting. There are two main types: inertia welding, where one component is spun up to speed before contact, and stir welding where a rotating probe stirs the material together. Friction welding produces very narrow heat-affected zones and strong welds for all geometries. It is used for alloys that are difficult to weld by other methods and provides advantages like reduced defects, weight savings, and dissimilar metal joining.

This document describes an experimental investigation of friction stir welding (FSW) process parameters and their effects on axial force generation. It outlines the design of the welding fixture and load cell used to measure axial forces. Experiments varied the rotational tool speed at three levels (800, 1000, 1200 rpm) and tool pin design with three angles (90, 100, 110 degrees) to study their impact on maximum axial forces during plunge steps. Results showed that higher rotational speeds and larger tool pin angles generally decreased the first maximum force, while only tool pin angle significantly affected the second maximum force. Optimized parameters were determined to be the highest rotational speed with tool pin designs at the 100 or 110 degree levels.

Friction-stir welding is an advanced solid-state joining process (the metal is not melted) which involves the use of a third body tool to join two facing surfaces. Heat is generated between the tool and material which leads to a very soft region near the FSW tool. It then mechanically intermixes the two pieces of metal at the place of the joint, then the softened metal (due to the elevated temperature) can be joined using mechanical pressure (which is applied by the tool), much like joining clay, or dough. It is primarily used on aluminium, and most often on extruded aluminium (non-heat treatable alloys), and on structures which need superior weld strength without a post weld heat treatment.
It was invented and experimentally proven at The Welding Institute UK in December 1991.

entire mechanical system to which the component has been used. In the light of the above the present work
mainly deals with the study of wear behavior of hot rolled steel with and without zirconia coating on the contact
surface and the effect of zirconia coating with varying thickness.

How to Verify the Number of SIM Cards Registered under your CNIC?
If you want to check how many SIM cards are registered under your name, you can do it easily. Just go to your mobile network provider’s website or app. Look for the feature called “SIM Ownership CNIC Tracker.” Then, type in your CNIC number correctly. After you submit it, the system will show you a list of all the SIM cards registered under your name. It will tell you which ones are active (in use) and which ones are inactive (not in use). Check this list carefully to see if there are any SIM cards you don’t need anymore. If you find any inactive ones, you can remove them to make room for new ones. This is helpful if you’re trying to add a new SIM card but all the slots are full. If you have any questions or problems with the registered SIM cards, you can contact your mobile network provider’s customer support for help.. By doing this, you can manage your SIM cards better and make sure you’re using your slots efficiently.

16. Metal Wear
Definition:
Is the removal of material from solid surface as a result of sliding action (Parts movement)
Forms of wear:
The principal/main forms of wear based on either its production OR operation (mainly we speak
about operation failures & sorts of wear)
Adhesive wear
It takes place during sliding; regions of adhesive bonding called (Junction) form between two
sliding surfaces. If one of these junctions doesn`t break along its original surface then a chunk
(Particles) from one surface will be transferred to the other surface forming adhesive wear.
After while this particle come off loose from the sliding surface and part after part it cause a
system failure.
The proper solution is always checking the greasing & use a proper lubrication.
Results of adhesive wear:
WEAR-OUT Mode: occurs after long period of sliding as too much material been removed
SEIZURE MODE: occurs in a system which particles size larger than clearance which results in
jamming the system
17.
18. Abrasive wear
It occurs as result of movement of hard/sharp surface to softer one and produces grooves & deep
scratches.
The abrasive agent might be part of the surface or different agent such as sand/dust, etc…
Abrasive wear is similar to adhesive wear in response & propagation but has different coefficient of
wear (mostly deeper).
19. Corrosive wear
This form of wear produced as result of sliding movement inside a corrosive environment, when sliding
action is in continuous movement it removes the protective coat layer of the metal, leave fresh
substrate against the corrosive media, which lead to rapid removal of metal particles.
Type of corrosive wear:
1- BIMETALLIC Corrosion: when two metals are in contact (different material) the more reactive in
electricity versus less reactive one, the more reactive dissolves to protect it.
20.
21. Cavitations Corrosion:
turbulence of flow gives high potential to form cavities within liquid resulting in
cavitations erosion. Collapse of these cavities produces shock waves resulting in
corrosion & pitting of surface. (results produced as an impact of stagnant pressure,
which transfer pressure to Vapor pressure with instant temperature up to 500C, in
certain cases)
22. Impingement/Velocity corrosion:
rough surfaces such as most of cast iron surfaces are exposed to impingement corrosion
much more than other surfaces because of high surface roughness. When fluid hits such
surface the flow became turbulent and results in impingement thereby accelerating the
erosion of metals and might lead to cavitations corrosion later on.
23. Entrainment corrosion:
Particles in suspension in any fluid system can result in rapid deterioration when the
system is being operated as result of particles/solids blasting against metallic surface
causing entrainment corrosion & metal losses.
24. Crevices & pitting corrosions:
it occurs on surface of metals as result of oxygen reaction with substrate, main different
that pitting is taking place on plane surface, CREVICE corrosion takes place in pockets.
Knife Line Attack:
it’s very familiar to be existed inside half filled steel water tanks, the line of corrosion is the
reaction between (Oxygen + bare steel + static level of water) seems very sharp & straight
line.
25. Surface fatigue wear/corrosion cracks:
This type of wear occurs as a result of cracks/hair cracks/subsurface crack formation &
growth; most of ball bearings, gears, wheels on rails suffer from same crack until failure.
Failure usually appears when a large particle leaves place as result of this crack growth.
26. Conclusion:
From all of the above and other reasons/types of metal defects (misalignment, bending,
buckling, cold cracks/hydrogen embrittlement, porosity & holes, segregations, shrinkages,
inclusions, etc…) that affect the operation, it is evident & proven by all operating sectors
(industrial, oil & Gas, irrigation, water treatment, chemical manufacturing, steel industry,
transportation, electricity, etc…) that metal defects are a predominant problem, and its
existence cost those operating houses (shut down time, replacement of new parts, labor
costs, decreasing production, etc…) which resulted in losing money to fix it, so from our
long experience it was proven that
``PROTECTIVE IS MUCH CHEAPER THAN CORRECTIVE``.
It’s always cheap & recommended to protect your new/semi-new equipment that to repair it
after failure, but if you have arrived to failure its better to rebuild, protect & restore the part
to service or to be a stock item condition B/C better than scrap it and purchase new part.
(especially while possibility is existed to recover it to service)
30. By using cold welding Technology INTERRA can perform
repairing and maintenance of various tools and equipment
