A weld flaw refers to any imperfection or defect that occurs in a welded joint, potentially compromising its integrity and performance. Common types of weld flaws include cracks, porosity, inclusions, and incomplete fusion. These defects can arise from various factors, such as improper welding techniques, material issues, or environmental conditions during the welding process. Identifying and addressing weld flaws is crucial to ensure the safety and reliability of welded structures and components.
A weld flaw that is large enough to render the weld rejectable typically includes significant defects such as deep cracks, lack of fusion, excessive porosity, or undercuts that exceed specified acceptance criteria. These defects can compromise the structural integrity and performance of the weld. The specific size and type of flaw that is considered rejectable can vary depending on industry standards and the application of the welded joint. In general, any flaw that affects the weld's strength or function and exceeds allowable limits is grounds for rejection.
A weld flaw large enough to render the weld defective typically includes issues such as cracks, porosity, or incomplete fusion. These defects can compromise the structural integrity and performance of the weld, leading to potential failure under stress. In some cases, misalignment or excessive undercut can also be significant enough to invalidate the weld. Proper inspection and quality control are essential to identify and address these flaws before they result in catastrophic failures.
A butt weld is a weld made between two straight cut profiles , a socket , or plug weld is made between a surface and a hole.
When done correctly it doesn't matter where a weld is made.
At first, the area of cross section of the weld, length of the weld, volume of the weld in cubic inches, weight of weld in cubic inches. To express in formula: Weight of Weld Metal = _ Êx ÊBase Êx ÊHeight Êx ÊLength Êx ÊWeight of Material.

This welder is certified to weld on pressure vessels. Testing is done on the weld either by X-Ray or pressure test. The root pass is inspected then the final pass is inspected during the test. If either inspection turns up a flaw, the test is over and you fail.

Depends on what you are welding, but generaly welds can meet, or even weld on top of a weld.
