the original electrode was made in this way!
The welding strip is a melting electrode used for arc welding with coating, and it is the basic welding material for manual arc welding. The variety of welding rod is complex, with many size , strict quality , short production cycle , strong continuous operation and big output . So besides having the best electrode design and correct selection of raw materials, there must be corresponding manufacturing process, equipment and strict inspection and testing methods in order to produce a high quality electrode.
The welding rod manufacturing process is summed up in the following seven major processes:
❶ Core processing (rust, drawing, straight cut nuclear);
❷ The preparation of the raw material of the electrode (comminution and sieve powder);
❸ Preparation and distribution of water glass;
❹ The preparation of welding rod coating;
❺ The press coating of the welding rod;
❻ Welding rod drying and packing;
❼ Inspection of the finished product of welding electrode.
