The main consumable materials required for submerged arc welding are the wires and fluxes Electrical Circuit and Setup For SAW 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 Typically an automated carriage is used to move the welding torch and flux hopper tube steadily down the welding seam Likewise automated wire feeding and voltage and current control are necessary to maintain precise control of the welding parameters Apr 19 Submerged arc welding is known as a process that can result in high welding speeds and deposition rates However in today& 39 s manufacturing reality engineers are always looking to boost productivity—even for already productive processes Fortunately companies have three common approaches to consider to increase the performance of their submerged arc welding systems Submerged arc welding SAW is a common arc welding process that involves the formation of an arc between a continuously fed electrode and the workpiece A blanket of powdered flux generates a protective gas shield and a slag and may also be used to add alloying elements to the weld pool which protects the weld zone Submerged arc welding is commonly used in industries where thick steel sheets are involved or where long welds are required The process consists in creating a welded joint between steel components using an electric arc submerged beneath a layer of powdered flux Saw welding for storage siloIn the submerged arc welding process the flux covered electrode is replaced by the granular flux and a bare electrode An arc between the electrode and job is the source of the heat and remains buried under a blanket of flux This flux keeps the atmospheric contamination away Aug 14 For welding vertical up use a push or forehand technique and tilt the top of the electrode 0 to 15 degrees away from the direction of travel Angle of travel When welding from left to right maintain a 0 to 15 degree angle tilted towards the direction of travel This is known as the drag or backhand technique the rays of the arc when welding or observing open arc welding Headshield and filter lens should conform to ANSI Z87 I standards 4 b Use suitable clothing made from durable flame resistant material to protect your skin and that of your helpers from the arc rays 4 c Protect other nearby personnel with suitable non flammable screening and

Submerged arc welding is also a much safer way of performing welds using arc welding There is a variety of saw equipment available including welding tractors that are used to automatically weld a seam and flux recovery units that use a vacuum to " hoover" up excess flux from the weld THE SUBMERGED ARC WELDING PROCESS 10 SUBMERGED ARC WELDING ELECTRICAL STICK OUT Electrical Stick Out setting The electrical stick out or CTWD contact tip to work distance is the distance set between the contact tip end and the work piece The stick out needs to be kept constant along the weld ifSAW Process Flux covers weld zone in front of wire Heat of the arc melts the wire flux and plate Fused flux shapes and protects weld metal Weld metal 6 Welding Power Supply • Supplies electrical power to the electrode The heat of the arc melts the electrode and base plate to form the weld bead • Electrical current can be Jan 29 April 1 Sandeep Anand Submerged Arc Welding SAW is an arc welding process in which arc is generated between a bare electrode and the workpiece The arc and the molten weld pool are submerged in a blanket of granular fusible flux on the workpiece Flux covers the arc and prevents fumes sparks spatter and intense ultra violet Submerged Arc Welding SAW is a specialized type of arc welding where a continuously fed solid or tubular electrode is used to form the arc between the two metals to be joined It was first patented by Jones Kennedy and Rothermund in the year where they covered an electric arc beneath a bed of granulated flux 4 Arc Welding Advantages The process gives high deposition rates Welding speed is high Wire consumption is low The consumption of electrical energy is low as a maximum of 97 % of heat energy can be utilized Any length can be welded without any interruption High quality Welds are achieved with no fusion defects no porosity and slag inclusions Submerged Arc Welding Definition This is an Arc welding process Discovered in by Jones Kennedy and Rothermund This welding is defined as the joining of metals with the application of heat and also granular flux Welding process used in long pipe welding Electrical poles and Turbines and extra May 03 A too slow travel speed can cause the weld metal to roll forward past the arc cushioning arc force into the base material Care must be taken when welding in a V groove especially at the bottom where it is easy to have excessive weld metal for the joint cross section This is obviously hard to notice in the SAW process
