How to test whether the flux cored wire is filled evenly?
In the process of production, the filling test of flux cored wire is usually done by measuring filling ratio in many ways.If you are the user of the wire, you can do a spot check section filling ratio test, you can also take the same weight detection.
There are several ways: 1, with pliers, welding wire, to see if you can go down a relatively deep card mark, and if it is easy to flat, and that is certainly not filled, 2, measuring powder loose loading ratio
In the production process, many measurements can be carried out in an appropriate position, and the filling rate is monitored by weighing calculation, or an automatic control device for molding on-line monitoring filling rate is adopted.But there are few good ways for users to make accurate measurements (as judged by chemical analysis of deposited metals)
