Manufacturing Process: The Jinlong Difference in AWS E6013 Welding Rod Production

The quality and performance of an electrode AWS E6013 largely depend on its manufacturing precision and the quality of raw materials. At Jinlong, our process is meticulously controlled to ensure every rod meets the highest standards. While traditional manufacturing processes for metal components often involve casting, forging, or CNC machining, the production of welding electrodes follows a specialized methodology focused on wire drawing, flux extrusion, and controlled baking. This ensures the optimal chemical and physical properties required for superior welding performance.

Step 1: Wire Drawing

High-quality carbon steel wire, precisely chosen for its chemical composition (e.g., low carbon content for mild steel electrodes), is drawn to the required core wire diameter (e.g., 2.5mm, 3.2mm, 4.0mm, 5.0mm). This process ensures uniformity and strength.

Step 2: Flux Mixture Preparation

A proprietary blend of rutile (titanium dioxide), cellulose, stabilizers, deoxidizers, and binding agents is precisely weighed and mixed into a homogeneous paste. This carefully formulated flux coating dictates the arc characteristics, slag properties, and mechanical properties of the weld metal.

Step 3: Extrusion Coating

The prepared core wires are fed into an extrusion press where the flux paste is uniformly applied around the wire. Advanced extrusion technology ensures concentricity and consistent coating thickness along the entire length of the AWS E6013 welding rod.

Step 4: Baking/Drying

The freshly coated electrodes are then transferred to controlled drying ovens. This critical step removes moisture from the flux coating, preventing hydrogen embrittlement in the weld and ensuring arc stability. Different temperature profiles are used depending on the specific flux type.

Step 5: End Finishing & Inspection

After baking, the electrodes undergo end grinding for easy arc striking. Each batch undergoes rigorous quality control, including visual inspection, dimensional checks, bend tests, and radiographic inspection of test welds to verify mechanical properties and absence of defects. We adhere to ISO 9001 quality management systems and ISO 2560 (Welding consumables — Covered electrodes for manual metal arc welding of non-alloy and fine grain steels — Classification) standards.
