A system and method for submerged arc metal powder welds includes modular programmable control of: a) a weld torch, and the position of the welding wire(s) from the torch traveling within a weld cavity, b) the rate of metal powder and welding flux added to the weld cavity ahead of the weld torch, c) the matching ratio between of metal powder and welding wire within the weld cavity, and d) a ...
The element transfer of Ti from molten flux to the weld metal is limited to less than 310 ppm Ti in the submerged arc welding of carbon steel. This limitation is due to the high oxygen partial pressure prevailing at the molten flux-weld pool interface. Our previous study illustrated that the use of Al powder in combination with Ti powder improves the transfer of Ti to the weld metal to 4% Ti ...
Submerged welding is an arc welding method where the heat necessary for the welding is generated by the arc(s) formed between a wasting electrode (or several electrodes) and the workpiece. The arc area welding powder layer as well as the welding metal and base metal close to the weld are protected by the melted welding powder (slag).
Stopping, reducing or recycling the waste generated in a process is an effective method to improve its productivity. Flux used in submerged arc welding/cladding gets converted to slag, which is a waste and is needed to be disposed off safely. The …
Most arc welding processes rely on a protective slag and/or a shielding gas to protect the weld metal from the atmosphere during welding. A granular material, known as flux, plays a vital role in submerged arc welding; flux may cost 50% of the …
Ana et al4 conducted a study for chemical and Keywords— Submerged arc welding, flux, agglomerated flux, structural characterization of fluxes used in submerged arc fused flux, recycling, redrying welding process, which enabled one to quantify the ions that might be present in the plasma arc due to fluxes.

The recycling of submerged arc welding slag for use in welding operations that are in accordance with the American Welding Society (AWS) Structural Welding Code, 01 .1-94, requires that each time the slag is recycled it be tested.
An explosive forming is one of the techniques to form a metal plate using high shock pressure from the explosion. An explosive releases its energy instantly so that an extremely high pressure with short duration occurs at the instance of explosion. The underwater shock wave travels downstream and then it hits the metal plate to be formed.
