material compatible with the base metal being welded. In case of any inadvertent strike on
place other than the welding, the area affected shall be ground flushed and examined by liquid
penetration method.
C) Generally, a stringer bead technique shall be used with a slight oscillation if necessary to avoid
slag and to minimize the number of beads needed to fill the joint. However, the width of the
deposited pass shall not exceed 3 times the wire diameter. Vertical welds shall be made in
upward direction. For whenever possible, by 2 welders working simultaneously along both
sides of the pipe.
D) All joint fit ups shall comply with the tolerances specified on the manufacturing drawings. The
root pass shall have less than 1.5 mm internal reinforcement. Defects like icicles, burn through
and excessive “suck bak”, etc. shall be cause for rejection of welds.
E) Final welds shall be suitable for appropriate fabrication of the non-destructive examination of
the weld. If grinding is necessary, the weld shall be blended into the parent metal without
gouging or thinning of the parent metal in any way. Uneven and excessive grinding may be a
cause for rejection. Fillet weld shall preferably be convex and free from Fillet weld shall
preferably be convex and free from undercutting and overlap at the toe of weld. Convexity and
concavity shall not exceed 1.5 mm. The leg length shall not exceed the specified size by more
than 1.5 mm.

temporary attachments shall be dressed smooth and examined by ultrasonic or liquid
penetration methods.
G) All tack welds shall be made using qualified procedure and welders, the number of size of tack
welds shall be kept as small as to consist of adequate strength and joint alignments. All tack
welds shall be examined visually for defects and if found defective shall be completely
removed. As welding proceeds, tack welds shall be either removed completely or shall be
properly prepared by grinding or filling their starting ends so that they may be satisfactorily
incorporated in the welds. Unacceptable defects shall be removed by grinding machine or
chipping or gouging. Flame gouging may be permitted provided gouged surfaces are ground at
least by 1.0 mm below the deepest indentation.
H) All weld repairs shall be carried out using the approved welding procedures and welders.
Preparation of weld repair shall have the prior approval of the Engineer’s Representative. Rewelded
areas shall be re-examined by the methods specified for the original welds and repair
procedures shall be duly qualified by the Engineer’s Representative.

of cross phasing, insulation resistance to earth and between conductors. Insulation
resistance tests shall be carried out with 500 / 1000 V megger.
b) The cables shall be supplied at site, wound on wooden drums as far as possible. For
smaller length and sizes, cables in properly coiled form can be accepted. The cables
shall be laid by mounting the drum of the cable on drum carriage. Where the
carriage is not available, the drum shall be mounted on a properly supported axle,
and the cable laid out from the top of the drum. In no case the cable will be rolled

other to the farthest point of the ECC. First, current through the circuit is measured with
the resistance of 2 ohms short circuited by the link. Next, current is measured through the
two ohms resistance by disconnecting the two leads from the ECC and joining them
together. If current is more in the first case, the resistance of ECC is less than 2 ohms.
