Abstract

Welding slag is slag or form a vitreous material obtained as a by-product of some arc welding processes, most particularly shielded metal arc welding, submerged arc welding, and cored arc welding.Slag is remaining remnants of the welding process, which is the result of the flow, doing my job. Slag derived from flow or decompose in a protective gas or deoxidizers that form fused compounds which cover the seam while it cools, to prevent oxidation of the newly formed weld. (Welding flow is a combination of carbonate and silicate materials used in the sealing process for protecting the weld from atmospheric gases. when heat from the weld zone reaches the flow stream of gas and melted. The gases produced to push back atmospheric gas, preventing oxidation. ) Slag is perfect to protect the weld while it cools, but as soon as it has completed its work, it must be removed before the next pass. Thus, there are many ways to remove welding slag, but The most common method was to hammer in the past years. But the hammer could damage the weld face leaving tiny traces of where the weld could fail. A chipping hammer is great for general purpose welding, in combination with a wire brush, the results are usually good. ... .hence There is a need for special purposes Machine to remove slag from the welded parts.
