In 2014, the United States was the world's third-largest producer of raw steel (after China and Japan), and the sixth-largest producer of pig iron.The industry produced 29 million metric tons of pig iron and 88 million tons of steel. Most iron and steel in the United States is now made from iron and steel scrap, rather than iron ore.

are involved in arc welding should knowledge of weld imperfections and have adequate preventive measures. This booklet, Weld Imperfections and Preventive Measures, is prepared to provide the information of common weld imperfections, causes, and preventive measures. The weld imperfections contained in this textbook are categorized into surface
The submerged-arc welding (SAW) process is similar to MIG where the arc is formed between a continuously-fed wire electrode and the work piece, and the weld is formed by the arc melting the work piece and the wire. 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 ...
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 non-biodegradable nature, this poses problems of storage, disposal, needs landfill space for dumping and this also causes soil pollution.
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 ...

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 (mini-mills) using an electric arc furnace process.
Jul 11, 2018· Recycling fused slag from the SAW process is economical and environmentally friendly. Submerged arc welding (SAW) slag is recycled by taking the fused part of the slag after welding and processing it in a manner that allows it to be reused for the same SAW operation.
In the Submerged Arc Welding (S.A.W.) 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.
a rough bead surface or slag that is unusually difficult to remove. In many instances these fluxes can be re-dryed in general welding applications. Recycling Flux • Remove slag, metal, mill scale, and any other contaminants from the flux. • Prevent damage to the .

Jan 30, 2019· Looks a little hot from the spatter. The slag is so hard to come off due to the heat and the undercut on the top edge of the weld. I believe 90 amps is the top end for a 3/32 or 2,4 mm 6013.... Also clean the mill scale on your plate it will help make a better weld. Other than the spatter and the undercut the weld itself looks good.
7018 slag will just about fall off by itself when you're running it right. For 6010 a 4 1/2" knotted wire wheel is nice to have as a time saver, but a hand wire brush is all you should really need. Most common mistake is not allowing the weld to cool off long enough before cleaning up.
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.
