Fig. 2. Pathologies in weld joint at steel water elevated reservoir: slag inclusions.

The weld joint with weld spatter, porosity and solidification cracking indicated the weld in high welding amperage (Fig. 3a). In opposite, excess weld metal, overlap, undercut were recognized as the joint in low welding amperage (Fig. 3b). At least, the incorrect storage of the welding electrodes indicated the use of moist welding electrodes (Fig. 3c).
