Welding Meaning Of Crater. A crater is a tiny explosion which will send droplets of molten metal in every direction. Consequently conditions which exaggerate the liquid to solid volume change will promote its formation.
Physical properties generally result in distortion and the heat transfer rates of the base material. You could probably search the Internet for an. If the weld area of a fil-let weld in a hole or slot calculated from this length is greater than.
Figure 1 shows an example of a crater shrinkage cavity in the weld crater which was made with a mild steel flux-cored gas-shielded wire.
A localized increase in volume in the region of a weld resulting from the application of pressure. Crater occurs due to residual stress imposed by. Causes of the crater. Incorrect profile Welding is not done properly.
