Especially when ignoring the body can mean ignoring the bodies of people we are hurting, in this land, in Israel, in Syria, in Tibet, all over the world. The body is the real, and itâs so easy to repress, because itâs so painful and vivid to feel.
Welding defect. A welding defect is any flaw that compromises the usefulness of a weldment. There is a great variety of welding defects. Welding imperfections are classified according to ISO 6520 while their acceptable limits are specified in ISO 5817 and ISO 10042.
These defects can be caused by cold dies, low metal temperature, dirty metal, lack of venting, or too much lubricant. Other possible defects are gas porosity, shrinkage porosity, hot tears, and flow marks. Flow marks are marks left on the surface of the casting due to poor gating, sharp corners, or excessive lubricant.
