 Note: to minimize the heat input to maintain the substrate at low temperature (less than 70 ℃ ????????) to reduce the possibility of occurrence of cracks. More than 3cm short of deposited weld metal should immediately hammer, and then again on the arc in the weld metal. Surface should be clean and free from grease welding (pre-polished connector.)
