3、焊等。1)手工电弧焊 它是焊条与母材之间产生电弧,靠电弧的高温熔化焊条与部分母材,在两焊件(母材)之间形成熔池,熔融金属在熔池中经过冶金反应后冷却,形成焊缝,把两焊件连接起来。第6页，本讲稿共24页第7页，本讲稿共24页DiagramGuild Design is one of aligned company with Microsoft Ltd,and we develop and provide the design templates for Office 97,2000,and XP.ThemeGallery is a Design Digital Content&Contents m
