weld n. 焊接(點),熔接點。 vt. 焊[熔]接;使密切接合,結合。 A welded joint 【機械工程】熔接頭。 vi. 被焊接[熔接]。 Welding powder 焊粉。 A welding rod 焊條。 Gas welding 氣焊。 Resistance weld 電焊。 A weld-less pipe 無縫管。 n. -er 1.焊工。 2.焊接機。 -ing 焊接 (welding torch 熔焊炬)。 n. 【植物;植物學】淡黃木樨草;(由淡黃木樨草采取的)黃色染料。
Brazing is a metal joining technique that exhibits its full potential when joining materials that are difficult to weld conventionally , such as different materials , steel alloys , or parts with thin structures , complex shapes , etc 可焊接其他焊接方法難以焊接的材料,異種材料和合金鋼,薄壁構造或者形狀復雜的部件加工,這種強有效的金屬焊接技術就是銅焊接。
It is a dozen metals in one ; now almost diamond - hard - - and again almost as soft as copper ; here brittle as glass ? there malleable1o as silver ; now welding quite readily - - again , very difficult to weld ; melting rather easily - - at other times difficult to diffuse ; usually very magnetic - - and : again almost non - magnetic ; an excellent conductor of heat and electricity - - and at times stubbornly resistant to both 鐵將十多種金屬特性合而為一:時而幾乎堅硬如金剛石,時而又柔軟如銅;此處易碎如玻璃,彼處又可展延如銀;時而很容易焊接,時而又很難焊合;有時相當易熔,有時又極難擴散;通常情況下富有磁性,但有時又幾乎磁性全無;本是熱和電的優良導體,但有時卻頑強地抗拒二者。
