Properties and Behaviour of MMA Welding Slag

Abstract

In the competitive world of welding consumables market the basic properties of the weld deposit like chemical and mechanical properties do not differ considerably to influence selection of a specific brand over the other. Selection is often decided on the basis of ease of welding, aesthetic aspects, reliability of the product etc., besides economic considerations. The ease of welding that is slag detachability, ease of striking and restriking of arc, capacity to absorb fluctuations in welding parameters etc., thus assumes high commercial importance.
