AWS E307-16

Description and Applications

HE307 is a retile type electrode for all positions, with an excellent resistance against crack. Slag is easy to remove and the arc is stable. Welding of 14% Mn steel, hardening steel and stainless steels to carbon steel. Used in building of rails and surfacing before hard facing onto 14% Mn steel.

 
Guideline in Usage
1. Electrodes should be re-dried at 250 300℃ for one hour before use
2. Excessively wide waving may cause welding defects. Keep weaving width to 2.5 times electrode diameter
3.

Remove all dirt such as oil and dust from the groove.
