Welding defects are generated in a welding job due to the faulty or poor technique used by the inexperienced or unskilled welder or due to fundamental difficulties in the welding operation. An ideal weld or good weld should be such that adequate fusion exists between the filler metal and edge preparation together with good penetration.
arc welding SAW Solid wire Argon gas High Steady Power sources produce DC with the electrode either positive or negative, or AC. The choice of current and polarity depends on the process, the type of electrode, the arc atmosphere and the metal being

Figure 14.29 shows the welding defects under unsuitable parameters. The defects are usually induced by the improper feeding speed of filler wire and the distance between filler wire and heat resource.The defects shown in Fig. 14.29(a), (b) and (d) are induced by insufficient melting of filler wire when the feeding speed of the filler wire is too high or the distance between filler wire and
Used properly, Personnel Protective Equipment (PPE) greatly reduces the risk of injury and minimizes the effects of toxins. PPE is required in the Laney College welding lab. If you do not wear approved PPE, you will not be allowed in the lab. You are required to
