Five Steps to Improving Your Stick Welding Technique

When welding “out of position” i e vertical and overhead positions you are welding against gravity Now you are much more limited as to the size of the molten puddle you can carry How fast the weld metal solidifies and the support of a fast freezing slag system if present are keys to successful out of position welding Flux cored arc welding Flux cored arc welding FCAW or FCA is a semi automatic or automatic arc welding process FCAW requires a continuously fed consumable tubular electrode containing a flux and a constant voltage or less commonly a constant current welding power supply An externally supplied shielding gas is sometimes used but often Jun 21 Advances in Self Shielded Flux Cored welding FCAW S wire and equipment have made it an increasingly viable option in manual pipeline welding applications compared to Stick welding SMAW Advantages include lower hydrogen content increased speed and deposition efficiency increased control of the arc and ease of use Fumes are produced in all welding and cutting operations They are a mixture of atmospheric gases arc shielding gases vaporised elements from the parent metal metal coatings or flux coated welding consumables airborne particles small enough to be inhaled Welding fumes are normally at levels low enough to pose no great health risk FCAW per the American Welding Society or flux cored for short is different in that it uses a wire which contains materials in its core that when burned by the heat of the arc produce shielding gases and fluxing agents to help produce a sound weld without need for the external shielding gas 3g dual shield flux core welding test vertical uphill weld test and a 4g overhead test too My friend Andrew Cardin placed 5th in the world skills welding competition held in Brazil back in So I asked Andrew if he could come help me film some videos on 3g and 4g welding tests A PUMA welding robot equipped with a SCR three phase Linde VI SS constant potential power source was used to perform FCAW with an AWS E71 ] 1 1/16 in 1 6 mm diameter elec trode The welding robot CPU provided command signals to an interface unit that controlled the welding parameters pre Jul 25 The specifications for this welding procedure are very simple compared to my other welding certifications The AWS D1 1 3G FCAW procedure qualifies you to weld in the 1F 2F and 3F positions and the 1G 2G and 3G positions You are qualified to weld in the flat horizontal and vertical positions and not the 4G or overhead position Jul 25 Flux cored arc welding is the most productive of the manual welding processes! When comparing MIG welding to flux core arc welding there is a huge gap in production in the amount of weld per hour A MIG welder can typically produce 5 to 8 pounds of weld per hour verses a FCAW welder packing 25 plus pounds of weld per hour

MIG Welding Techniques Paterns and Angles for All Position

Sep 26 I have qualified numerous GMAW/FCAW procedures over the years and they were always performed with the torch angle at / 10 degrees from vertical for flat/downhand welding The biggest problem I found was the welders on the shop floor would change the torch angle to suit themselves and this would lead to varying depths of penetration/fusion A Gas marks are small grooves that sometimes appear on the surface of a weld made with the Flux Cored Arc Welding process FCAW whether it is gas shielded flux cored FCAW G or self shielded flux cored FCAW S welding Excessive levels of dissolved gases in the weld metal are the cause of gas marks Flux cored arc welding FCAW also know as dual shield welding is a semi automatic arc welding process that is similar to metal active gas MAG W uses a continuous wire fed electrode a constant voltage welding power supply and similar equipment to MAG welding Mar 26 FCAW GMAW welding parameters By CHGuilford Date 20 48 We use 71M as our standard wire Parameters depend on the work D1 1 D1 5 maintenance etc but we do run at 29V/A with % CO2 for our D1 5 WPSs That was the only way we could consistently get 5/16" 2F fillets in a single pass That allows a fast enough travel to Mar 24 If you& 39 re welding material more than 1/8 in thick with short circuit transfer GMAW consider welding vertical up only when no other welding position is practical And even then consider changing your process to flux cored arc welding FCAW or if the power source is available pulsed GMAW A metal sheath is drawn around metal powder and other flux elements to form the finished FCAW wire An important part of this procedure is the seam left after the drawing process This seam should be structurally sound so that it will support the core throughout the welding process Nov 27 The main difference between flux cored arc welding and GMAW welding is the way the electrode is shielded from the air Flux cored arc welding just like the name implies has a hollow wire with flux in the centre just as the name states a ‘Flux Core’ Types One type of FCAW requires no shielding gas The power supply for a FCAW and a MIG welder are the same machine They are both considered semi automatic processes and have a very high production rate Difference between a MIG weld and FCAW weld is the slag covering In this picture you can see how the slag peels by itself What is the Difference Between FCAW and MIG Welding
