Digital WPS: introduction

A Digital Welding Procedure Specification (dWPS) is a WPS in digital format that automatically adjusts the settings of X8 MIG Welder when selected.

A WPS is a document that describes how a particular type of weld is to be carried out. It defines the welding parameters, and provides direction to the welder or welding operator. The goal is to achieve quality welds and repeatability in production. A separate WPS is developed for each material alloy and each welding type.

Kemppi's WeldEye cloud service provides tools for creating and editing WPSs. When the welding system is connected to WeldEye, dWPSs are automatically transferred to the power source memory of all welding machines connected to WeldEye. If no Internet connection is available, it is possible transfer the dWPSs on a USB stick. The user can then view, activate and select the dWPSs with Control Pad. It is also possible to select dWPSs through the wire feeder display or the welding gun remote control.

When a dWPS is selected, the welding system settings are automatically adjusted accordingly. This decreases the possibility of errors and makes the work faster and easier as manual adjustments are not necessary. However, fine tuning of the parameters is still possible. The user can see the detailed information about the dWPS as well as the related joint design and welding sequence drawings on the Control Pad. No paper copy of the WPS is needed. As the same dWPSs can be automatically transferred to several welding machines, it is easy to have the same settings in all the machines.
