Pit Depth Gauge Measurement Techniques

The video tutorial explains the use of a pit depth gauge, a versatile tool for measuring various weld defects. It covers how to measure pit depth, undercuts, surface porosity, and outside misalignment. The tutorial provides step-by-step instructions for each measurement type, emphasizing the gauge's precision and versatility.

What is one of the primary uses of the pit depth gauge?

• To measure the temperature of a weld

• To measure pit depth and other weld defects

• To calculate the weight of a material

• To determine the color of a weld

How should the pit depth gauge be positioned to measure pit depth?

• Place it on the highest point of the material

• Lower it to the surface and gently lower the pointer into the pit

• Hold it above the material without touching

• Use it to scratch the surface of the material

What is the minimum diameter of pits that the gauge can measure?

• 3/4 inch

• 1/8 inch

• 1/4 inch

• 1/2 inch

When measuring undercuts, where should the pointer be placed?

• At the highest point of the undercut

• Outside the undercut

• At the lowest point of the undercut

• In the middle of the undercut

How is aligned surface porosity measured using the gauge?

• By placing the gauge on top of the weld

• By placing the gauge at a 45-degree angle

• By placing the gauge along the length of the weld

• By placing the gauge perpendicular to the weld

What increments are used on the scale for measuring aligned pores?

• 1/4 inch

• 1/8 inch

• 1/2 inch

• 1/16 inch

How can you compare the size of surface porosity using the gauge?

• By estimating visually

• By using a magnifying glass

• By using the 1/8 inch or 11/16 inch holes in the gauge

• By using a ruler

What is the correct method to measure outside misalignment?

• Hold the gauge above the pipes without touching

• Use the gauge to scratch the surface of the pipe

• Place the gauge on the ground

• Set the gauge on one pipe and extend the pointer to the adjacent pipe

Where can the pit depth gauge be purchased?

• From an online auction site

• From a local hardware store

• From a welding supply store

• From G Gauge Company
