The weld access hole or rat hole is a structural engineering technique in which a part of the web of an I-beam or T-beam is cut out at the end or ends of the beam. Structural dampness is the presence of unwanted moisture in the structure of a building, either the result of intrusion from outside or condensation from within the structure. To help site visitors understand more about metal casting and foundry operation terms and terms associated with the iron foundry and other metal foundry industries, Atlas Foundry Company has included this one-of-a-kind glossary. Home > Glossary of Foundry Terms > A . In children, a common appearance of the hymen is crescent-shaped, although many shapes are possible.During puberty, estrogen causes the hymen to change in appearance and become … A breach hole is an opening that is made in a structure using mechanical, ballistic, explosive, or thermal means to facilitate the entry of assault elements. CONCRETE: A mixture of cement, sand, and gravel with water. ... gentle application of the hands to a specific structure or body area to determine size , consistency , texture, symmetry ,and tenderness of underlying structures ... hole that completely penetrates a structure: Term. Closure, die — A term frequently used to mean variations in thickness of a forging. SPT Abbreviation for Standard Penetration Test. Term. Capillary penetration of fluid from the ground up through concrete or … Heat Treatment hepatitis: Definition. The heat from welding may change a metal’s hardness. Hardness: A metal’s ability to resist indentation, penetration, and scratching. Definition.. "a depression caused by the soil and other materials subsiding into an open hole or void below the ground surface" Typically classified as either Cover Collapse or Cover Subsidence Sinkholes. A high proportion of damp problems in buildings are caused by ambient climate dependent factors of condensation and rain penetration. This is an industry standard test that is used to determine the density of subsurface soils. The hole in the web allows a welder to weld the flange to another part of the structure with a continuous weld the full width on both top and bottom sides of the flange. Grain Structure: The relationship between the small, individual crystals in an alloy or metal. The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain.It is subdivided into the facial bones and the brain case, or cranial vault (Figure 1).The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws. (A fillet welded slot should not be construed as conforming to this definition.) The hymen is a thin piece of mucosal tissue that surrounds or partially covers the external vaginal opening. Cogging — The reducing operation in which an ingot is worked into a billet by the use of a forging hammer or a forging press. The hole may be open at one end and may be partially or completely filled with weld metal. Without the weld access hole, the middle of the flange … The results are quantitatively consistent with this perspective: 1 to 3 holes with an average 340-nm diameter per cell would mean 1 to 3 μm of hole wall perimeter. CONDITIONS AND RESTRICTIONS: The term used to designate any conditions to which the use of land may not be put and the penalties for failure to comply. suppuration: Definition. inflammation of the liver: Term. They serve to stiffen the roof structure. COMPUTER AIDED DESIGN: Using the computer to perform drafting and design functions. Coining — (1) A post-forging process—on hot or cold parts—used to attain closer tolerances or improved surfaces. Glossary of Foundry Terms - A .
