Dye penetrant examination of the completed weld. 對已完成的焊縫進行著色滲透檢測。
Weld identification single hole punch. 鑒別焊縫的單孔衝壓機。
This welding backing is used with all one-side processes.Especially for those which do not demand back bead cleaning. 本襯墊可用於各種單面焊接工藝的位置，特別適用於不一定要求封底焊道的場合。
To gain fine mechanical property and bead strength to raise welding efficiency and quality, only applicative welding parameters and shielding gas rate could attach to the target. 摘要就焊接的目的而言，正確的焊接參數組合及適當的遮護氣體比例才能使母材獲得良好的機械性質及焊道強度，提高焊接效率與品質。
