The present paper describes fuzzy logic simulation of shielded metal arc welding (SMAW) process to predict the Quality of weld joint. It describe the quality of weld joint & effect of welding current, voltage and welding speed on tensile strength of shielded metal arc pipe welded mild steel joints. An ERW Mild steel pipe I S 1239 of 6 mm thickness and 150 mm diameter were used as the base mater...

The thermal shrinkage technique with previously proposed input parameter values for single-pass welding was applied to a multi-layer butt-welded joint four layers and six passes validate whether these parameters are applicable welded joints. out-of-plate displacement distributions of the obtained using were in good agreement those elastic-plastic analysis an experiment. angular distortion trans...

An analysis was made of the application Stud Welding hardware welding technologies depending on welded structures used, duration process, shape stud butt and consumables used. The use CD technology for metalware to thin-sheet panels is substantiated. essence process formation a joint described, which consists in explosive evaporation protrusion at end during discharge capacitor banks, excitatio...
