To use the Travel Speed calculator insert the the time taken to complete the weld and the weld length into boxes of formula 1 Next input your recorded welding Amps and Volts into formula 2 and it will calculate the Heat Input VEL SPEED CALCULATOR [Input the time taken & the length of weld]The same formula is used to calculate the other pollutants with their corresponding emission factors Potential Chromium tons/yr = Potential Manganese tons/yr = Potential Nickel tons/yr = ACTUAL EMISSIONS Actual PM2 5 tons Actual PM10 tons 40 1 lbs x 5 4 lb/1 lbs x 1 ton/2 lbs = tonsGas Metal Arc Welding Basics Welding Current & Welding Voltage Introduction Gas metal arc welding GMAW is a welding process that has been commercially available for around 60 years The basic operation of the GMAW process occurs when an electrical arc is established and maintained between a base material and a continuously feed wire electrode Endurance Limit = 0 5 Tensile Strengthor kpsi which ever is lower Pumping law in the High and ultra high vacuum regions After a sufficient time the pressure will reach equilibrium and the pumping equation simplifies to the form shown earlier P t =Q t /S t In most practical cases the pumping speed is a constant but there are important exceptions Mar 28 You can determine the welding speed experimentally or just assume a round number of 10 inches per minute The circumference of the weld is times the Diameter If the diameter is 10 inches then the circumference is 31 4 inches 10 inches per minute divided by 31 4 inches is approximately 1/3 RPM very slow The formula is welding speed Adjust the tap switch so that proper welding current can be obtained with the % current set between 70 and 90% The only time the % current should be set below 70% is when the tap switch is on its lowest setting and 70% current is still too high Electrode Force is the result of air pressure applied to the air piston connected directly to the head Jan 26 Simply select the picture which most resembles the welded connection configuration and loading condition you are interested in for a list of relevant weld stress formulas Tee Plates Flat Plates Lapped Plates Plug and Slot Bar to Plate Beam to Plate Rod to Plate Mar 09 Welding Stepper Program Sample 3 SPCC 1 2 x SPCD SD 1 4 x SPRC 40 2 0 kgf Graph Part Combination Nugget Diameter Standard Welding Pressure Graph 3 6 8 10 12 14 16 18 20 Weld Time cycle WeldCurrent A Weld Current versus Weld Time Graph weld_current_total vs weld_time_total

4 Equipments Used The high pressure gas welding plant consists of oxygen and acetylene cylinders pressure regulators piping high pressure torch etc 5 Purity of Acetylene The acetylene obtained from cylinder is pure 6 Labour There is no additional labour is required as the acetylene gas is available in cylinder Note If a leg length h= 1 2mm is used in the equations in relevant part of the " Table of bracket weld subject to direct and bending stresses" above a value of τ b = N/mm and a value of τ s = N/mm 2 results with a resultant stress of Sqrt τ b 2 τ s 2 = N/mm 2 Which is in general agreement with the above resultPower requirement also increases with the increase in axial pressure 4 At the same welding rate the welding speed is mm/min and the rotation speed is r/min the welds at different welding pressures are shown in Fig 16 6 This chapter discusses the following pressure welding methods Resistance welding including spot welding seam welding projection welding resistance butt welding and flash welding Friction welding including friction welding by rotation friction surfacing and friction stir welding The places when the particles cluster together are volumes of high pressure so these waves are also called pressure waves Sound waves are an example of pressure waves and they can move through gases liquids and solids For sound waves the denser the medium the faster the speed Speed through air 1atm 20 0 = m s 1Jul 22 Not sure if there is a formula to figure that out or not being that there are so many different variables Material thickness joint design preheat voltage/amperage type of steel process position and skill of welder But yes the larger the diameter the higher the deposition rate so travel speed usually goes up as well JasonTo use the Travel Speed calculator insert the the time taken to complete the weld and the weld length into boxes of formula 1 Next input your recorded welding Amps and Volts into formula 2 and it will calculate the Heat InputModel testing is carried out over the expected speed range of the ship with resistance data collected at each testing speed Effective horsepower is then calculated and plotted as shown in Figure 7 4 It will be observed from the figure that the doubling of speed of the Navy YP from 7 to 14 knots increases the power by a factor of 10!Sep 20 Welding speeds are dependent upon the deposition rate of the process Say 1lb per hour the production factor say 5 the deposition efficiency of the These are just random values but one major variable is the production factor

Pre Calculating Wire Feed Speed Travel Speed and Voltage

Knowing at what level you operate at is important in setting your weld schedules The formula shown below is based upon standard AC 60 cycle welding with a one minute integration time period Reference RWMA – Resistance Welding Manual Section 19 3The welding current is the most important parameter in resistance welding which determines the heat generation by a power of square as shown in the formula The size of the weld nugget increases rapidly with increasing welding current but too high current will result in expulsions and electrode deteriorations Nov 20 I want to know an average time required for the welding Medium Skilled Welder Carbon Steel & Stainless steel plates for pressure vessels For Eg Say 10mm Thick Plate how much time will be required to weld 1 meter of double v joint 3 pass Is there a formula or an excel sheet for calculating such timimgs At the same welding rate the welding speed is mm/min and the rotation speed is r/min the welds at different welding pressures are shown in Fig 16 n the welding pressure is relatively lower a pore is formed at the bottom while with a suitable welding pressure the weld is good and there is full penetration These formulas allow the welder to carry out several operations such as calculating shapes and volume determining the pressure and volume of gases and figuring out how temperature changes will affect pressure Understanding formulas not only means knowing how to use them in calculations it means looking at a formula and knowing what it means Aug 08 Weld Weight and Area Spreadsheet Calculator Calculations for Double V Single V Compound V Backing Strip and J groove weld weight and area Weld Branch ASME B31 3 Excel Calculator Spreadsheetwelding power bus so that the number of welds with low voltage is about 1 or 2 per thousand then it is very unlikely you will get cold welds due to low powerline voltage The statistical assumptions and approximations in this spreadsheet are accurate with 5 or more welders With more than welders and/or if the welders have a very highRolling resistance sometimes called rolling friction or rolling drag is the force resisting the motion when a body such as a ball tire or wheel rolls on a is mainly caused by non elastic effects that is not all the energy needed for deformation or movement of the wheel roadbed etc is recovered when the pressure is removed
