The work reported deals with developing a recycling technology for converting SAW slag into a fresh flux. The slag generated during submerged arc welding is normally thrown away as a waste. Owing to its nonbiodegradable nature, this poses problems of storage, disposal, needs landfill space for dumping and this also causes soil pollution.
Oct 15, 2016· From the literature review, it was observed that although some research has been done on mixing, reuse and recycling of SAW slag generated during welding of low and medium carbon steels, no published literature regarding any attempt to recycle the SAW slag for .

However, in SAW a shielding gas is not required as the layer of flux generates the gases and slag to protect the weld pool and hot weld metal from contamination. ... in pipe mills, the most common multiwire systems have two wires ...
Apr 19, 2019· Thanks for your info Tommyjoking, but the slag came from Submerged Arc Welding as you know it generates a huge amount of slag. In history, we normally crushed the slag to consider as Recovered, mixed it with Flux (25% Recovery and 75% ) and used it in production, but we stop that practice due to Customer requirements and related quality issues.
Slag recycling in submerged arc welding and its influence on weld quality leading to parametric optimization ... To determine the optimum condition of process parameters to achieve efficient mill ...
Submerged arc welding (SAW) is widely used in heavy industry fields, such as ship buildings or steel pipe mills. Some papers pointed out that recycle use SAW slag to SAW flux is effective to ...
Oct 11, 2007· Slag generated during conventional submerged arc welding (SAW) has been recycled by mixing varying percentages of crushed slag with fresh flux to use in subsequent runs. The influence of using fluxslag mixture on various aspects of SAW weld parameters of bead geometry have been investigated in a quantitative basis.
The slag occurs as a molten liquid melt and is a complex solution of silicates and oxides that solidifies upon cooling. Virtually all steel is now made in integrated steel plants using a version of the basic oxygen process or in specialty steel plants (minimills) using an electric arc furnace process.

In the Submerged Arc Welding () process the weld takes place under a blanket of granular "flux", whatever flux comes in contact with the arc (or heat) of the weld becomes a homogeneous glass like structure and is commonly referred to as "Slag". This "Flux Slag" can now be crushed (reprocessed) into a reusable SAW consumable.
