What is a weld profile gauge?

  • Welding Contour Gauge. A weld profile gauge is just the right tool for testing welding profile, matching wheel arches and body contours, or forming panels. Simply press the gauge against the piece you want to copy.

The adjustable fillet weld gauge uses an offset arm that slides at a 45-deg angle to make fillet weld length measurements. You simply adjust the arm until it touches the toe of the vertical leg. The gauge is calibrated to 1/32 in. Four screws hold the offset arm in position for future adjustments.

What is a fillet gauge used for?

A radius gauge, also known as a fillet gauge, is a tool used to measure the radius of an object. Radius gauges require a bright light behind the object to be measured. The gauge is placed against the edge to be checked and any light leakage between the blade and edge indicates a mismatch that requires correction.

How do you measure a fillet weld?

Fillet weld sizes are measured by the length of the legs of the largest right triangle that may be inscribed within the fillet weld cross section.

What is checked with weld fillet gauge?

Welding gauges are inspection gauges used for checking alignment, checking dimensions before welding, verifying weld dimensions, and checking porosity of welds. Some gauges are multipurpose or single purpose.

What are weld gauges used for?

Measuring Fillet Welds A weld gage is a simple hand-held device that lets the welder or weld inspector, check the size of the fillet.

What is a fillet weld symbol?

The fillet weld symbol is a right triangle placed on the reference line with the perpendicular leg always on the left. The dimension specifying the leg size of a fillet weld is placed to the left of the fillet weld symbol, and on the same side of the reference line.

What is the weakest plane in fillet weld?

For a given amount of weld material, the fillet weld is not as strong as due to the heavy concentration of the stress. ∴ For fillet weld, the weakest plane is along the throat section.

What is the maximum size of fillet weld?

The maximum size of fillet weld is obtained by subtracting 1.5mm from the thickness of the thinner member to be jointed. When welds are applied to round toe of steel sections, the maximum size of the weld should not be more than 1/3 of the thickness of the section at toe.

What is the minimum size of a fillet weld?

Explanation: The minimum size of fillet weld should not be less than 3mm and not more than thickness of thinner part joined.

How do you measure groove weld?

Determine the weld size. This includes the depth of groove and the additional penetration into the root. The size of weld will be shown to the left of the groove symbol in parenthesis. If there is no number in parenthesis then the size of the weld should not be less than the groove depth.

How do you size a weld?

A basic understanding of related terminology is assumed. To develop the full strength of a plate using fillet welds, it is necessary that the leg size of the fillet be 3/4 of the plate thickness. A fillet weld with this leg size will out-pull its plate under any magnitude and direction of loading.
