Type | GB Code | AWS Code | Description |
H08A | H08A | EL8 | Low manganese low silicon welding wire matches with high manganese and silicon welding flux,not sensitive to the rust on the base metal;has good welding shaping and slag removal performance;it is the most frequently used submerged arc welding wire,can be used in single and double pole,AC and DC welding.Cooperated with melting-type welding flux HJ431 or sintered welding flux SJ301 and SJ501,suitable for the high-speed welding of 420Mpa class base metal,and filling welding of 450Mpa carbon steel and low alloy steel. |
H08MnA | H08MnA | EM12 | Medium manganese medium silicon welding wire matches with medium manganese and silicon welding flux,not sensitive to the rust on the base metal;has good welding shaping and slag removal performance;it can be used in single and double pole,AC and DC welding.Cooperated with melting-type welding flux HJ350 or sintered welding flux SJ301,suitable for the high-speed welding of 420Mpa class base metal and filing welding.It is used for the corresponding strengthen level of low-alloy steel welding of ships,chemistry,bridges and steel structure. |
H10MN | H10MN | EH14 | Welding line metal with good mechanical properties can be obtained by cooperating with the corresponding welding flux(e.g.HJ230 and HJ350),used for the submerged arc automated welding of carbon steel and low alloy steel such as15Mn and 14MnNb;cooperated with the sintered welding flux SJ101,suitable for the high-speed welding of 42Mpa class base metal and filling welding.It is used for engineering welding such as ships. |
