Indy/Life. Eating disorders such as anorexia and bulimia cost the country more than Â£15bn a year, according to the first analysis of the financial effects of the problems.
The centerline crack show on this fillet weld is the result of. low melting point material segregation (or segregation weld. cracking). Crater cracking occurs when the welding operator stops welding prior to finishing a pass on a weld joint, leaving a wide, thin depression at the end.
Surface contain. irregularities include uneven weld bead ripples, excessive weld reinforcement, excessively. concave or fillet weldconvexs, unevenleg fillet weld- s, undercut, overlap, herringbone, pockmarks, mouse footmarks, and underfill. Weld discontinuities can be defined as an. interruption of the typical structure of a weld, such as a lack of homogeneity in the mechanical, metallurgical or physical characteristics of weld.. Weld discontinuities include porosity, the. slag inclusions, incomplete fusion, incomplete joint penetration, excessive melt-through, cold. cracks, and hot cracks. However, a surface irregularity or weld discontinuity is not a rejectable.
