Calculating cooling time t8/5. With its simple and self-explanatory menu navigation, the EWM cooling time calculator is a powerful aid when it comes to calculating the required cooling time and ensuring the desired welding result. Calculating the volume of a weld is one of the first steps to be taken when. The arc time (the length of time that an arc is burning and depositing weld metal).
Weld Pattern Calculation ExampleNote: 'h' is entered as the weld throat thickness and Iₒₒ and Iᵣᵣ are the second moments of area about the z-z and y-y axes of the welding calculator respectively ( Fig 1) ApplicabilityWelding applies to any welded joint whereby a sectional shape is welded to a fixed and solid base. There is no limitation to the shape that can be calculated but, you will need to enter the second moments of area of the shape concerned and the weld pattern for irregular shapes, which can be calculated using CalQlata's or calculators or found in CalQlata's database. AccuracyWelding’s calculations are exact within the limitations described above and the integrity of the user’s input data and the quality of the weld(s).

I am an estimation engineer. I want to know an average time required for the welding (Medium Skilled Welder) Carbon Steel & Stainless steel plates for pressure vessels.
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??Also if any of you have an easy method to calculate the weld metal deposit and welding gas (Oxygen, Acetylene and argon) consumption.??Please help.Thank yougregorydas RE: Calculate Welding Time?

Brimstoner,That can have two effects depending on what the welders think they are being monitored for. If welders are paid on a production basis, they tend to slow down, so that they can get more time/money for the next job issued. If they think it is for a pending layoff, they 'know' the slowest guys get let go first, so the tendency is to speed up. Either one skews the results, It is better to monitor without being observed.B.E.You are judged not by what you know, but by what you can do. RE: Calculate Welding Time? (Industrial) 15 Dec 14 08:43.
To calculate the welding cost, you need to consider the below elements.Manpower cost1- Welder ' Craft Cost ', It is pertinent with his productivity and salary ' Paid to emp. And fringe benefits '2- Overhead cost: Supervision and management.Material Cost1- Welding machine depreciation or rent.2- Consumables ' wire brush, grinding disc.etc'.3- Welding electrode cost,it is pertinent with welding bevel profile. To compute the metal volume, you need to define the area and perimeter of pipe, then Volume of metal deposit will come through math, all waste sources shall be considered through that formula.Equipment Cost1- electricity cost ' either by Power meter or Diesel cost + operation cost of Genset '. You need to search for KW need per Kg of metal deposit, and add an allowance for idle operation. KG of metal deposit should be calculated after knowing the welding bevel profile, welding procedure, No of joint and Dia of each joint.it is not an simple estimation job, but once you made it, you can use it for ever with little amendment and improvement.
Finally you will reap what you has seed. RE: Calculate Welding Time? For 'close enough' values of 'n'.
