Using input from customers, welders, engineers, floor managers, trainers, and internal staff we have created the most robust, user-friendly collection of welding-specific calculators in one, elegant and easy-to-use app.
The AMI Welding Calculator app includes the following features:
• Heat Input Calculation
• Energy Density Calculation
• Power Ratio Calculation
• IPM and RPM Conversions
• Pulse Conversions
• Deposition Rate
Users can also save or share calculations using the mobile operating system sharing capabilities. Users can also select either English or Metric units. Logic within the app clearly prompts the user for valid input using a unique input block system.
1) Real time display angle value reference by horizontal axis.
2) 2 mode for using(mode 1 and mode 2).
3) Graphics Animation display related by mode.
4) Display 0 to 90 degree reference by horizontal axis.
5) Calibrate option for accuracy.
Colored text boxes show you which values you entered while the white one's show the calculated values.
On Screen Keyboard makes entering values easy and fast without the android keyboard popping up and down to get in your way.
No need to hit calculate because after every key press the calculator will solve for the missing values if enough information is available saving you time and key presses.

To assist welders, welding supervisors and inspection personnel to control welding heat input in the field.
Welding heat input is one of the most difficult aspects of welding to control out in the field, because the Heat Input (HI) is a function of the welding current, voltage and travel speed. While many modern power sources will give a reading for the voltage and amperage, when performing manual or semi-automatic welding, the travel speed can only be calculated in hindsight, and hence the heat input can also only be calculated in hindsight. This means that controlling heat input turns into a trial and error endeavour. The Heat Input Helper (HIH) application has been developed to overcome this difficulty by giving a continuous feedback regarding the maximum and minimum distances that should have been welded to stay within the target maximum and minimum heat input limits.
How Heat Input Helper Works:
By entering the actual Voltage, Amperage and weld length, along with the target values for maximum and minimum heat input, the application provides you with a constant visual output of the maximum and minimum distances that you should have welded to be within those heat input limits. It therefore soon becomes apparent if the welder's travel speed is too fast or too slow, and timely remedial action becomes possible.
Heat Input Helper Application Features:
1) Continuous minimum and maximum weld distances are shown, to give continuous feedback regarding progress required to stay within the target maximum and minimum heat input values.
2) You can use millimetre or inch units.
3) Heat inputs are continuously logged during the weld run, so if the voltage and amperage parameters are adjusted during the weld run, the new parameter values are only applicable to the time in which they remain active, and do not influence previously logged values.
4) A pause button is provided, to allow for times when the welder needs to break the arc.
5) A delay timer is built into the heat input helper application. This will assist a welder that wants to perform his own heat input checks, when s/he does not have anybody else to push the buttons for him / her. This function will perform the specified delay (say 6 seconds) before commencing the timer, and deduct this same amount of time from the total time when pressing the pause or finish button.
6) At the end of the weld run, the average heat input and the welding travel speed of the weld run is shown. This allows you to record these without further calculation, if required.
An HTML5 version of the heat input helper application is freely available for use and evaluation on the WelderPassport website. Please visit: www.welderpassport.com to evaluate the application.
The total pressure loss in the system results from the combined losses due to friction in length of pipe and friction losses due to valves, fittings, and other components. The first are "major losses" associated with energy loss per length of pipe, and seconds are "minor losses" associated with bends, fittings, valves, etc.
The factors that determine friction losses in pipe are:
The velocity of the water: As velocity increases, pressure losses increase. Velocity is directly related to flow rate.
The size (inside diameter) of the pipe: Smaller pipe causes a greater proportion of the water to be in contact with the pipe, which creates friction. Pipe size also affects velocity. Given a constant flow rate, decreasing pipe size increases the water’s velocity, which increases friction.
The roughness of the inside of the pipe: Pipe inside wall roughness is rated by a C factor, which can be selected depending on material of pipe. The lower the C value, the rougher the inside and the more pressure loss due to friction.
The length of the pipe: The friction losses are cumulative as the water travels through the length of pipe. The greater the distance, the greater the friction losses will be.
The friction losses for, elbows, and tees can also be selected. The friction losses in fittings such as couplings, elbows, tees, valves and other elements play a role. Friction loss from these components must be taken into account when calculating friction losses for each section of pipe.
Calculation of friction factor is based on the Hazen-Williams equation. Local resistances factor K for valves and some fittings (tees, elbows, pipes contraction and enlargement), can be found in app itself.
Calculate pressure losses in a pumping of 10 l / s. The diameter of the suction and discharge is 100 mm or 4 ". We have the following items on the Suction: 1 foot valve, 1 gate valve , 1 elbow 90, 1 contraction to 3" to entering the pump. In the discharge we have: 1 expansion, 2 elbow 90,
a check valve, 1 gate valve. The total pipe length is 10 meters in diameter of 100 mm. Must be calculated the pressure losses for the given flow.
I wrote this app to double check my onsite welding calculations when time is of the essence and the client is counting the seconds.
Note: This app was written essentially for a smart phone to be used on site.
Version 2 Uploaded 6 Sept 2014 (not shown in screenshots)
- Adapted App for use on older phones (Android 2.2, API Level 8, Froyo)
- Added allowance calculations including:
Heater plate temperature
Minimum weld width after cooling
Maximum weld width after cooling
It has two modes - First and most popular is for Nominal Pipe Sizes from ½” thru 24” Standard Weight Pipe (the default setting). It can solve size on size or any intersection where the branch is smaller than the main.
Second - it will solve any round size on another round size of any thickness. Note the entry mode changes where exact outside dimensions (OD) are required plus the branches wall thickness. This is required as the inside of the branch connection fits onto the outside of the main.
In either case the results are the ordinates for 16 points to lay out the lateral. Plus it gives the take off from the wrap-o-round line to the center of the main for any degree used.
Of course we’re assuming you’re a journeyman pipefitter (steamfitter) and know how to layout the pipe when the calculated ordinates are given.
