There are different ways to tag information like operator, work order, filler metal type and lot, to a specific welding session: 1. Adding those information directly into WeldCloud Fleet as described [here](/en/article/how-to-add-traceability-data-into-weldcloud-fleet-3frfig/) 2. Sending data to a specific welding power source via WeldCloud Assembly. Please follow this [article](/en/article/send-weld-details-to-a-connected-equipment-for-welding-parameter-traceability-1lcjabz/) for details 3. Using WeldCloud Link app for Android devices In this guide we will cover WeldCloud Link app scanning feature to add traceability data to weld sessions. Scanning process is usually performed by the welder/welding operator using any Android device with WeldCloud Link app installed. You can find more details on those articles: * [Getting started with WeldCloud Link app](/en/article/getting-started-with-weldcloud-link-app-185w9b6/) * [WeldCloud Link first login](/en/article/weldcloud-link-first-login-11jmcxk/) Few prerequisites need to be fulfilled for a successful scanning with WeldCloud Link: 1. At least one welder/welding operator is created as personnel member. More details [here](/en/article/personnel-and-user-management-in-indusuite-apps-1l29hwd/) 2. Welder/Welding operator is authorized to access a specific power source through a [machine permission group](/en/article/how-to-create-permission-groups-for-your-welding-machines-syuu55/) 3. Welder/Welding operator knows his operator ID. This is set during the personnel member creation process. Please ask a WeldCloud admin user in your company to provide your operator ID (**Assumption**: __welder/welding operator does not have a WeldCloud account__) **Now you are ready to boost your welding traceability with WeldCloud Link following below instructions!** **1.** Open **WeldCloud Link** app on your Android device ![Open WeldCloud Link app on your Android device](https://storage.crisp.chat/users/helpdesk/website/-/1/c/b/d/1cbda94eeb4b4100/step01_l84j6a.jpg) **2.** Click **Skip** ![Click Skip](https://storage.crisp.chat/users/helpdesk/website/-/1/c/b/d/1cbda94eeb4b4100/step02_o37v88.jpg) **3.** Click **Connect** ![Click Connect](https://storage.crisp.chat/users/helpdesk/website/-/1/c/b/d/1cbda94eeb4b4100/step03_1uku0n.jpg) **4.** Tap on the welding machine you want to connect to ![Tap on the welding machine you want to connect to](https://storage.crisp.chat/users/helpdesk/website/-/1/c/b/d/1cbda94eeb4b4100/step04_nlo3x0.jpg) **5.** In case it is the first time your Android device is trying to connect to your welding equipment, you will be prompet to pair the devices.
