• Welding penetration refers to the depth that the weld extends into the base metal.

• A standard level of welding penetration is usually considered to be at least 1/16 of an inch.

• In some cases, inadequate welding penetration can lead to weak or faulty welds.

• Inspecting the weld penetration is important for ensuring the quality and strength of the weld joint.

Least count of a checking instrument refers to the smallest measurement that can be read or detected by the instrument.

• Least count is determined by the smallest division on the scale of the instrument.

• For example, a ruler with millimeter divisions has a least count of 1 mm.

• A Vernier caliper with divisions up to 0.1 mm has a least count of 0.1 mm.

• The least count is important for accurate measurements and precision in readings.
