Because TIG welded joints without filler wire always hold low strength and poor formation, tungsteninertgaswelding process with filler wire is inevitable.
At present, tungsteninertgas (TIG) welding method is one of the most widely used methods for its advantages of economy and convenience.
目前，经济实用的钨极氩弧(TIG)焊接方法是应用最为广泛的焊接方法之一。
