Calculators and tools: full overview
All calculators and lookup tools on the site gathered in one place: welding rod consumption, welding tables, material selection, generator sizing and power bank capacity.
Select the tool you need
The tools below calculate the factors that most frequently cause uncertainty in a project: how much welding rod is required, which welding parameters apply to the dimension, whether two materials can be joined, and what size generator or power bank is needed.
Three of the calculators can be used directly on this page – select a calculator in the field below. The remaining tools can be opened by clicking the name in the table. All calculators provide indicative figures. They are based on standard joint geometries, manufacturer data and simple rules of thumb described in each individual article – and they should always be verified against the machine's rating plate and the manufacturer's instructions.
| Tool | What it calculates |
|---|---|
| Welding rod calculator | Consumption of welding rod in grams and kg per metre of joint, 3 kg spools, broken down by V-joint, X-joint and fillet weld, as well as method and material |
| Welding tables | Welding parameters per dimension and material, root gap, bead width and welding force for butt fusion as well as electrofusion data |
| Material lookup | Properties, welding, application and identification for the thermoplastic types for which we have data |
| What can be welded together? | Select two materials and see whether joining them is possible, restricted or not recommended – and where we do not have data |
| Generator requirements for electrofusion fittings | Recommended kW, kVA and power bank capacity in Wh based on fitting dimension and number of joints per charge |
| Generator requirements for butt fusion | Recommended generator in kW and kVA based on the machine's rated power, including requirements for AVR and pure sine wave |
| Material pairs and designations | The difference between PE 100 and PE 300, as well as which material pairs can be welded |
The calculators are for guidance only. Always check the machine's rating plate, manufacturer's table and the relevant DVS 2207 part before completing and documenting a joint.

What can be welded together?
Select the two materials you wish to join and see the assessment. The tool is based on generally recognised combinations and notifies you when data is unavailable.
Not recommended
No - not a load-bearing joint
PE and PP are different polymers and cannot be welded together with a load-bearing result. They may appear to hold together, but the joint will fail under load.
The assessment is for guidance only and does not cover load, media or temperature in the specific application. Welding must always follow the manufacturer's instructions and the relevant DVS 2207 part, and a test must confirm the strength before the joint is used in a load-bearing application.
How to use the figures in practice
Start by looking up the dimension and material, then use the calculator to size procurement and power requirements. The welding rod calculator provides procurement figures, the welding tables provide the machine parameters, and the generator calculators provide the power rating and capacity required on site.
If a project requires documentation, the welding record log and machine data logger apply – not a spreadsheet. Read about the requirements in welding log and documentation.
If you are missing a tool or would like the figures reviewed for a specific project, ask an advisor – we are happy to assist with the calculations.
