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.
9 LONGITUDINAL CRACKING Longitudinal or centerline cracking, of the weld bead is not often encountered in mig welding. However, that which does occur can be one of two types: hot cracks and cold cracks. Typical hot cracks are shown in Figure 10-5. Hot cracks are those that occur while the weld bead is between the liquidus (melting) and solidus (solidifying) temperatures. In this temperature range the weld bead is âmushyâ.
