"Submerged arc welding
is a particular technique that we have perfected and is a requirement of the oil and gas industry, so we had eight to ten guys working on it for 18 months to make sure it went as smoothly as possible.
ICE offers a flexible solution to the shipyards that currently use the submerged arc welding
De, "Probing influence of welding current on weld quality in two wire tandem submerged arc welding
of HSLA steel," Science and Technology of Welding and Joining, vol.
In the process of submerged arc welding
, melting of materials powder spread over base metal surface or inserted into flux enabled to obtain alloyed, well melted with base metal welded layers.
Important to mention are the numerous applications of FCAW, such as: * FCAW is replacing SMAW for many applications, replacing GMAW, primarily the C[O.sub.2] version, and replacing submerged arc welding
(SAW) for thinner metal * FCAW is also used for surfacing and for buildup * The metals weldable by FCAW are: Cast iron, low carbon steel, low alloy steel, high and medium carbon steel, alloy steels, stainless steels limited types * FCAW has been widely used for welding in bridges, high rise buildings, ship building and offshore drilling platforms, main frames on bulldozers, rotating frames for shovels and cranes, tractor frames, bridge girders, large gantry cranes, furnace tubes, diesel engine chassis etc.
Gas Tungsten Arc Welding (GTAW/TIG), Gas Metal Arc Welding (GMAW/MIG), Shielded Metal Arc Welding (SMAW/"stick"), Submerged Arc Welding
(SAW), Electric Resistance Welding (ERW) and Laser/Hybrid Laser-Assist Welding.
Submerged arc welding
(SAW) is one of the most widely used processes for fabrication of thick plates, pipes, pressure vessels, rail tanks, ships, heat exchangers etc.
A welding flux could be applied by pouring it over the weld pool in a granular form as in submerged arc welding
process, it can also be coated on the exterior of the bare electrode as is the case of shielded arc welding or the flux could be placed in the interior core of the electrode as is the case of flux core arc welding.
The 2 head shapes were joined by submerged arc welding
to obtain a weld having high notch toughness.
Mandal works from his experience teaching courses on specialty welding, particularly that appropriate to shipbuilding, such as sheet metal arc welding, gas metal arc welding, gas tungsten arc welding, submerged arc welding
and electro-slag along with single side and multi-electrode welding techniques.
The 89 skill standards are categorized into these 11 areas: analysis (5 standards); setup (11); material preparation (7); shielded metal arc welding (17); gas metal arc welding (10); flux core arc welding (7); submerged arc welding
(2); gas tungsten arc welding (14); surface welding (1); quality assurance and documentation (8); and automated and mechanized welding (7).
