This paper is about the study of various mechanical properties of fiber reinforced cast iron by employing the gas metal arc
welding technique. The welding joints were assessed by measuring the tensile strength. Some specimens were preheated to
275° C for 8 minute and their results were compared with those of unpreheated specimens. The weld joints were cooled in air
and sand thus giving various cooling rates leading to different mechanical properties. The higher cooling rate produces
joints of higher strength and hardness with lower elongation. Preheating improves the strength and elongation and lowers
the hardness. This paper shows the properties of cast iron along with various important parameters.
Keyword: Strength, Joint, Properties, Cast iron.

Engineers throughout the world including India have used FRP to solve their structural problems in an efficient and
economical manner. In the field of Civil Engineering, most of the use of FRP is confined to repairing and strengthening of
structures. FRPs offer an added advantage over conventional materials and methods of retrofitting. Like other materials,
FRP also has its limitations. After presenting a brief review on these dimensions, this paper provides thorough information
on the compatibility and application of FRP in Civil Engineering in India.

This paper presents an automatic arc welding system used for the analysis of the depth of penetration on different specimens
welded at different welding speed. Automatic arc welding system has been designed using mainly a six axes vertically
articulated robot, Jigs/fixtures Programmable Logic Controller (PLC), Human Machine Interface and electrical control
panel. Electrical control panel has been used to control the arc welding robot and jigs/fixtures. The basic system controlling
diagram has been presented with I/O address assignment table. The design of jigs/fixtures has been carried out and selection
of servo motors/drives, arc welding robot, PLC has been made. In this paper, a system has been presented and demonstrated
to assist and simplify industrial welding procedures. The welding current, arc voltage, welding speed and heat input rate are
chosen as welding parameters. Analysis of depth of penetration of welded specimen has been carried out varying the
welding speed. The depth of penetration was measured for each specimen (butt joint) after each weld cycle by varying the
