How To Use A Fillet Gauge?

What do you do with a welding Fillet gauge?

  • First thing first, the two types of measurement that you do with a Fillet Welding Gauge is checking throat thickness and checking leg length.

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.

How is a fillet weld measured?

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 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 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 minimum size of a fillet weld?

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.

What are the 3 types of fillet joints?

​ Tee Joint, Lap Joint, and Corner Joint.

How do you read a fillet weld symbol?

The vertical leg of the symbol will always be placed to the left regardless of which way the arrow is pointing. Fillet welds may have a size associated with them. This size is called out on the left side of the symbol before the vertical side. The size is indicating the leg length of the weld.

Do weld gauges need to be calibrated?

Atema recommends a 5 year re-calibration date for gages used as a Master set.

What you will measure to determine the size of a convex fillet weld?

The size of a fillet weld is determined by its ‘leg length’. The figure is pretty theoretical – it depicts an equilateral triangle – whereas a real weld is never flat, and will be either concave or convex, and not necessarily equal-length legs.

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.
