430Mpa Hand Electrode For Low Carbon Steel
Application&Standard&Note：
1. Welding ordinary strength of low carbon steel structure and low strength grade of low alloy steel.
2. The standard we met: GB/T5117 E4303, AWS, ISO2560-A:E 35 0 R 1 2, ISO 2560-B: E4303A, JIS Z3211 E4303
1. The insulator must be cooked, and the electrode must be baked at 180°C. When it is being welded in the workshop, it needs to be placed within the insulation cylinder.
2. Pay care when welding: To make sure the welding region is clean, it is vital to remove any oil or other contaminants from a 20mm radius around the weld before welding. The welds must be clean, bright, and free of corrosion. Proper welding form is required (according to the welding manual grinding welding) 3. The welding environment, including the wind and dust. Pay close attention, 4, the rate of welding: a typical welding rod weld length is 40CM."
Features
1. Titanium calcium type c hemical skin carbon steel electrode.
2. Stable arc, good slag fluidity, easy slag removal, small splash, beautiful shape.
The Chinese name for the GEM-F03 low carbon hand electrode is J422, while the international label is E4303. J stands for the structural steel electrode, 42 equals 420 kg/mm2, and denotes the tensile strength of the weld metal. It is an acid electrode of the coated titanium calcium type. Used for welding LOW carbon steel structures and low strength grades of low alloy steel, commonly used for welding steel structures and standard carbon steel pipe."
