E6013 LT·J421 2.0/2.5/3.2/4.0/5.0 mm Carbon Steel Electrodes
E6013 electrodes is a great selection for all types of mild steel fabrications or repairs where ease of operation and good bead appearance are required.
Conform to Standard
GB/T 5117 E4313
AWS A5.1 E6013
ISO 2560-B-E 43 13 A
Typical Applications
General-purpose fabrication
Metal buildings and structures
Machine parts
Shaft buildup
Purpose:It is suitable for welding structures made of low carbon steel, performs very well in welding thin and small size steel plates and also has very good performance in the situation that requires nice and clean bead appearance.
Specification:J421 is rutile-based carbon steel electrode. It has very good welding usability that enables it to perform all-position welding, operates on AC/DC, removal of slag is easy, has stable arc and also has very good bead appearance. It is easy to operate, which makes re-striking the arc easy.
