Welding is the process joining two or more similar or dissimilar metal by the application of heat or sometimes pressure. called submerged arc welding process. The main objective of this review paper is to study and understand the various components, equiptments used and the effect of process variables such as welding current, welding speed, electrode, electrode angle etc that direct influences the tensile strength, hardness, bead width, bead reinforcement, depth of penetration etc. Welding is a fabrication or sculptural process which sole purpose is to join the materials. In current era of technology without welding technique we will reach to a stone age. So welding is one of the most useful fabrication process and it is the backbone of industries like construction industries, railways industries, aircraft industries etc. SAW which is
In this current scenario of globalization, foundries play a key role for manufacturing industries as they are the major source of castings. As a key industry a foundry's performance should be effectively high in terms of production with minimum number of rejections. Castings are the major inputs for most industrial products hence foundry industry is most indispensable. Casting is an integrated process considered as an artwork with experienced professionals for high quality yield, even then in highly controlled environment defects are dominant to take place leading to rejections, contrary to rejections a foundry's key attempt is to satisfy the demands neglecting quality levels. The challenges of casting defects are to be identified and minimized for effective castings. This study provides an intense knowledge of critical casting defects and their root cause analysis. In this paper efforts are made to achieve technically feasible remedies for minimizing several casting defects and improving the quality of castings which will serve as control measures for quality control professionals with zero defect concepts.Analiza defekta liva u livnici i uklanjanje nedostataka: pregled. U trenutnom scenariju globalizacije, livnice igraju ključnu ulogu za proizvodne industrije jer su glavni izvor odlivaka. Kao ključna industrija, performanse livnice bi trebale biti efektivno visoke u smislu proizvodnje uz minimalan broj škarta. Odlivci su glavni pripremak za većinu industrijskih proizvoda pa je livarska industrija najneophodnija. Livenje je integrisani proces koji se smatra umetničkim radom sa iskusnim stručnjacima za postizanje visokog kvaliteta prinosa, čak i onda kada su u visoko kontrolisanim uslovima dominantni nedostaci koji dovode do odbijanja, nasuprot odbijanju ključni pokušaj livnica je da zadovolji zahteve zanemarujući nivoe kvaliteta. Pri nastanku kvalitetnih odlivaka potrebno je indentifikovati i minimizirati greške koje se javljaju pri livenju. Ova studija pruža intenzivno znanje o kritičnim defektima livanja i analizi njihovih uzroka. U ovom radu su napravljeni napori da se postignu tehnički izvodljivi lekovi za minimiziranje nekoliko grešaka u livenju i poboljšanje kvaliteta odlivaka koji će služiti kao kontrolne mere za profesionalne kontrolore kvaliteta sa konceptom nulte greške. Ključne reči: greške pri lijevanju, dijagram uzroka i posledica, centrifugalno lijevanje, analiza defekata.
