Requests to use filler metals manufactured to other standards must be in writing and approved by SECCO prior to use. 使用按其它標準生產(chǎn)的填充金屬，必須事先提出書(shū)面申請，并獲得賽科公司的批準。
However, for attaching nonpressure parts to pressure parts, the filler metal chemistry shall match the nominal chemistry of the pressure part. 但將非受壓元件焊接受壓元件時(shí)所用的填充金屬，應與受壓元件的標稱(chēng)化學(xué)組成相配。
A pouring apparatus for molten metal includes a stirrer installed in a reservoir. 熔化焊料澆注裝置包括安裝在儲蓄器中的攪拌器。
Casting can be performed quickly after charging the metal particles into the molten solder, so the metal particles do not significantly melt into the molten solder. 在將金屬顆粒裝入熔化的焊料中后可立即執行鑄造，因此金屬顆粒不顯著(zhù)地熔入熔化的焊料中。
A type of self-shield metal cored wire for hardfacing is studied in the paper. 研制了一種自保護金屬芯堆焊藥芯焊絲。
Using high speed photography and ANALYSATOR HANNOVER, metal transfer modes of flux-cored wire were observed and analyzed.The reseach results are confirmed. 采用焊接過(guò)程的高速攝影技術(shù)和漢諾威焊接質(zhì)量分析系統對藥芯焊絲的熔滴過(guò)渡形態(tài)進(jìn)行觀(guān)察分析。
