Root pass is the first pass or the root penetration, filling is between the first and the second pass while capping is the covering.
Partial Penetration Weldments could be tested using Ultrasound Testing method. It should not be used to evaluate the intergrity of the weld but could be used to detect the root penetration and the depth. Godfrey Tisseverasinghe
A tap root system is identified by a single main root that grows vertically downward, with smaller lateral roots branching off from it. It has a carrot-like appearance with a dominant central root. Plants with tap root systems typically have deep root penetration into the ground.
Impassible has a root word, "pass." "Im-" is a prefix, and "-able" is a suffix.

A root cellar should be at least 4 feet deep to effectively store produce and maintain a cool temperature.

A root pass is crucial in welding because it establishes the foundation for the entire weld joint, ensuring proper penetration and fusion between the base materials. It helps prevent issues like incomplete fusion and porosity, which can compromise the integrity of the weld. Additionally, a well-executed root pass facilitates subsequent layers, ensuring that they bond effectively and maintain the desired strength and quality of the finished weld. Overall, it sets the stage for a successful welding process.
