Welding defects Prevention of lack of fusion Use correct welding technique Welding parameters Welding speed MIG gun angle and stick out Use correct recommended types and sizes of welding grooves Use correct welding power Use correct arc length Use correct groove angles and openings Change position of earth cable to the better place in work. WELDING DEFECTS AND THEIR REASONS OBSERVED IN 2012-07-11آ all welding defects that occurred during. Welding is a materials joining process which produces coalescence of materials by heating them to suitable temperatures with or without the application of pressure or by the application of pressure alone and with or without. As we know that in Casting we some defects are always there and similarly in welding defects are there. Indeed recently has been hunted by consumers around us, maybe one of you. Individuals are now accustomed to using the net in gadgets to see video and image data for inspiration, and according to the name of this article I will discuss about Welding Defects Ppt. Welding materials tensile test strength. Any irregularity discontinuity or flaw in the weld metal which exceeds the applicable code limit is termed as a WELD DEFECT. The various types of external defects with their causes and remedies are listed below. Welding Defects - kauackr Documents. Low-carbon aka mild steel is widely used for. 232004 31550 AM Document presentation format. An ideal weld or good weld should be such that adequate fusion exists between the filler metal and edge preparation together with good penetration. Please note that a discontinuity can be termed as a defect only when if it exceeds the specified code limit hence we can say that every defect present in a weld metal is a discontinuity but every discontinuity present in the weld metal may not necessarily be a defect.

It is deduced that the defects nearer to the surface reduce the strength of the welded joint more than those noticed in deeper layers. In the end a preliminary analysis was made on correlation between welding defects and mechanical performance of spot welds.
