Why Can We Always Ensure Excellent Quality

Quality Control

We have quality control equipment in production and good QC term.

The advanced visual inspection system can monitor the appearance quality of copper-plated welding wire in real time at the speed of 30 m / s, take 15 photos per second, compare with the standard color in the database, give an abnormal alarm and stop.

Longteng Special Steel Group

Wire diameter detector: it can realize on-line monitoring of welding wire diameter, and the inspection accuracy reaches micron level. In case of abnormal alarm and shutdown, the flow of unqualified products to the market is avoided.
