TIG-50
特性與用途：
適于軟鋼及490MPa級高強度鋼之造船、石油化學(xué)、核能電廠管路等高壓設(shè)備場合之管件對接及角焊用。
TIG-50使用純氬氣做TIG保護氣體，可全位置作業(yè)特別適于管路之第一道打底焊接，使用直流負(fù)電極(DC-)施焊。
注意事項：
(1) (1) 所使用之氬氣保護氣體純度要在99.997%以上且氣體流量控制要適當(dāng)，通常焊接電流在100~200 Amp時，氣體流量約7~12 L/min；200~300 Amp時，氣體流量約12~15 L/min。
(2) (2) 施焊時須有適當(dāng)?shù)姆里L(fēng)設(shè)施，否則保護氣體易受風(fēng)的影響而致氣體保護不良使焊道劣化而發(fā)生氣孔。
(3)適當(dāng)選擇集氣瓷杯及控制鎢電極的恰當(dāng)伸出長度。
(4)母材表面之銹層、油污、灰塵等須確實除凈。
