Carbon steel welding rod

Carbon steel rods is suitable for the carbon steel and the low intensity of low alloy steel welding.

welding rods Selection according to the steel chemical composition, mechanical properties and crack performance requirements, but also consider the welding structure, steel plate thickness, working conditions, stress, welder performance factors comprehensive analysis. When necessary, do welding test, formulate the corresponding technical measures, and determines the selection of electrode.

In order to ensure the quality of welding process , workpiece joint should be clean, no oil, rust,
Moisture, paint and dirt, etc., it is particularly important to use low hydrogen type electrode
