... the weld or isolated in small groups. They can also be concentrated at the root or toe of the weld. Porosity in welds is caused by gas entrapment in the molten metal, by too much moisture on the base or filler metal, or by improper cleaning of the joint during preparation for welding. The type of porosity...

... air from the substrate surface. The high viscosity of many adhesives in their liquid state makes the removal of air bubbles difficult, even when a vacuum is applied. Moisture, either in the adhesive or on the substrate surface, may also be a source for bubbles when the system is heated [ Packham 1990...

... in excessive flow rates should be avoided where erosion-corrosion may be a problem ( Fig. 8 ). Gaskets in flanges should fit properly, intrusions in a flow stream should be avoided, and elbows should be given a generous radii. Finally, crevices should be avoided. Where crevices cannot be avoided, they should...

... ) shows a schematic of how sliding slip planes can establish a surface configuration that results in extrusions (projection of material above the surface) and intrusions (missing material below the surface). Experimental evidence, attributed to W.A. Wood, is shown in Fig. 10.24(b) . Fig. 10.24...

... of popcorn, which are actually miniature pressure vessels. When all kernels are placed in the same environment (hot air or hot oil), the internal pressure in each kernel increases as the moisture turns to steam. Eventually, the internal pressure (or stress) will equal the strength of the hull, the strong...
