Where does the hydrogen in arc welding come from?
The principal source of hydrogen is moisture contained in the flux, i.e. the coating of MMA electrodes, the flux in cored wires and the flux used in submerged arc welding. The amount of hydrogen generated is influenced by the electrode type. Basic electrodes normally generate less hydrogen than rutile and cellulosic electrodes.See all results for this questionWhat can carbon arc welding be used for?1.

What are the consumable materials for submerged arc welding?
The main consumable materials required for submerged arc welding are the wires and fluxes. Fig 8.1 shows the electrical circuit for SAW while Fig. 8.2 shows the block diagram. An actual setup for automatic submerged arc welding is shown in Fig. 8.3. Mainly two types of weld joints viz., butt and fillet are made by submerged arc welding.See all results for this questionWelding Railroad Rails: electric welding, rod, preheat and cryogenic rail tank cars Submerged arc weldingFor arc welding carbon steel rail, I use Railend 932-0 stick, 1/4" at close to 300 amps cryogenic rail tank cars Submerged arc welding or Railend 932-0 wire 1/16" at varying currents up to nearly 300 amps. the rail is preheated to abnout 800-1000 degrees (black-red heat in sunlight) before welding, and kept hot during the weld. post-heating to same temperature and "natural" cooling rate to ambient.Welding Manipulators - Head Locator | MITUSA, Inc.TIG / MIG / Submerged Arc Manipulators for automatic welding of pipe, tanks and vessels.
