１ 磁偏吹的存在及其危害性电站建设中，焊接质量是保证机组安全运行的至关重要因素，而电弧燃烧的稳定性是保证焊接质量的先决条件。正常情况下，手工钨极氩弧焊的焊接电弧是非常稳定的，但在实际焊接过程中，往往会遇到因被焊管母材本身带有磁性，引起焊接过程中电弧发生偏?
The existence of magnetic partial blowing and its harmfulness In the construction of power station, welding quality is the crucial factor to ensure the safe operation of the unit. The stability of arc burning is a prerequisite for guaranteeing welding quality. Under normal circumstances, the manual GTAW welding arc is very stable, but in the actual welding process, often encountered due to being welded with the parent metal itself with a magnetic, causing the arc occurred during the welding process?
