Measure any
fillet weld to 1/32" accuracy with just one simple to
use gauge.
Measuring fillet welds used to
be a trial with complicated or inaccurate gauges. Not
any more. Now you can measure fillet welds from 1/8" to
1" (with ±1/32" accuracy) with one economical, simple to
understand gauge.
The G.A.L. Fillet Weld Gauge allows
fast, accurate measurement of eleven
(11) fillet weld sizes: 1/8, 3/16, 1/4,
5/16, 3/8, 7/16, 1/2, 5/8, 3/4, 7/8 , and
1", and their metric equivalents, to
determine weld sizes, either concave
or convex.
Why the gap between the pipe end and the internal
shoulder of the fitting before welding?
The function of the gap is to permit thermal expansion
of the pipe. Without the gap, the heat of welding can
cause the pipe to expand at a faster rate than the
fitting. If the pipe bottoms against the socket fitting,
the thermal growth of the pipe strains the weld,
possibly producing cracks in the root. Failures have
also been observed in socket welds subjected to thermal
and mechanical cycling during service. The mechanism is
similar to failure during welding. Rapid temperature
changes cause the pipe to expand against the bottom of
the fitting, straining and cracking the weld.
Construction and Military codes such as ANSI, ASME,
NAVSEA- 250-1500-1, MIL-STD-278 and MIL STD-22 permit
socket welds to be used, provided a minimum 1/16" (1.6
mm) is established between the pipe end and socket prior
to welding.
Inspection mirrors are known for their seemingly
limitless uses both around the home and in the shop. For
instance, an inspection mirror can be used to check
behind an armoire for lost keys or beneath an engine
block for a missing bolt. Inspection Mirrors are popular
for welding inspection as gives precise information
about weld. Inspection Mirrors come in a variety sizes
and lengths, and feature dual balland- socket joints for
infinite angle adjustments of the mirror. Inspection
mirror has telescopic extension to reach upto 16”.
This kit was designed for the Quality Control department
in the welding industry for pipe, structural, etc., to
be used where extreme accuracy is required in determ
ining depth of pits, gouges, undercut, crown height,
etc.
A simple, cost effective and accurate temperature
measurement/monitor can be made using irreversible
temperature indicating strips / labels. These labels are
also popularly called as temperature sensorlabels, shelf
adhesive temperature strips/ labels / decals etc. To monitor
the surface temperature, the required temperature
strip/label should be affixed on the surface of the object.
A white crystalline solid, sealed under heat resistant
transparent window, changes from WHITE colour to RED or
GREEN or BLACK color (depending on the user requirement)
once surface of the object attains to the rated temperature
of the circle.
A simple, easy, cost effective temperature indicating
sticks. Ball pen type, easy to fit in shirt pocket,
environment friendly temp stick are used in production shops
for quick quality control within accurate to +/- 1% of the
rated temperature. Temp sticks – Temperature indicating
crayon sticks or temperature sticks are available from 500 C
to 12000 C with broad range with choice of selections.
Quickly determines if fillet welds meet NRC Visual Weld
Acceptance Criteria for Structural Weldments
The V-WAC™ Gage easily and quickly checks the four essential
measurements required for compliance with the NRC Visual
Weld Acceptance Criteria. Checks undercut depth, porosity
comparison, amount of porosity per linear inch and crown
height. An essential and recommonded welding inspection
gauges GAL Gage Co. manufactured V-WAC™ Gage can be
purchased separately or as part of a complete set of seven
fillet weld gauges that determine if your welds conform to
specifications.
American Welding Society Structural Welding Code D 1.1
Paragraph 9.25 Quality of Welds 9.25.1.5 “Undercut shall be
no more than 010 in. (0.25 mm) deep when the weld is
transverse to the primary stress in the part that is
undercut.”
A handy compilation of mathematical relationships between
leg length, throats, skew angles and inspection dimensions.
A must for designers and inspectors. The perfect companion
to the GAL Weld Gauge.
Replaces all other sets of gauges to measure fillet or
groove welds in skewed members or members at 90 degrees.
With the new improved GAL Gauge A.W.S. Gauge shown above it
is possible to meet specifications of butt and fillet type
welds. New edesigned instrument is pocket sized and easy to
operate, new feature includes thumb screw which replaces old
hard to perate rivet type.
Diagrams at left illustrate the ease with which welders and
inspectors may accurately check sizes of convex or concave
fillets as well as butt weld reinforcements.
