WELD METAL ANALYSIS (RANGE) %
MECHANICAL PROPERTIES (RANGE)
• Proper preheating (50 - 150°C) and interpass temperature must be used in order to release diffusible hydrogen which may cause cracking in weld metal when electrodes are used for medium and heavy plates.
• Gas flow rate is proper 20-25 l/min.
• Shielding gas should be used Ar + 20-25% CO2
CURRENT CONDITION : DC +
