L312 | Wire & rod | 595-605 |
| Brazing of copper, copper alloys, steel and stainless steel etc. | 七、焊條藥皮類型及主要特點(diǎn)。按照藥皮的主要成分可以確定焊條的藥皮類型。由于藥皮配方組成不同,致使各種藥皮類型焊條的熔渣特性、焊接工藝性能以及焊縫金屬力學(xué)性能有很大差別。即使是同一類型藥皮,但不同牌號(hào)的焊條也因?yàn)樗幤こ煞趾团浔炔煌笚l的工藝性能等也會(huì)出現(xiàn)明顯的差別。 | |
L313 | Wire & rod | 625-635 |
| Brazing of copper, copper alloys, steel and stainless steel etc. | BAg-1a | |
L321 | Wire & rod 絲 | 615-650 |
| Brazing of copper, copper alloys, steel and stainless steel etc. | BAg-7 | |
L323 | Wire & rod | 665-755 |
| Brazing of copper, copper alloys, steel and stainless steel etc. | (6)藥皮類型:纖維素型 電源種類: 直流或交流 主要特點(diǎn):藥皮中含15%以上的有機(jī)物,30%左右的氧化鈦,焊接工藝性能良好,電弧穩(wěn)定,電弧吹力大,熔深大,熔渣少,脫渣容易。可作立向下焊、深熔焊或單面焊雙面成形焊接。立、仰焊工藝性好。適用于薄板結(jié)構(gòu)、油箱管道、車輛殼體等焊接。隨藥皮中穩(wěn)弧劑、黏結(jié)劑含量變化,分為高纖維素鈉型(采用直流反接)、高纖維素鉀型兩類 | |
L325 | Wire & rod | 645-685 |
| Brazing of copper, copper alloys, steel and stainless steel etc. | BAg-36 | |
L326 | Wire & rod | 650-720 |
| Brazing of copper, copper alloys, steel and stainless steel etc. | BAg-34 | |
Aluminum base 鋁基 | L400 | Cast rod, wire & rod | 577-582 | Si11.5 | Brazing of aluminum and aluminum alloys. | BAlSi-4 |
L401 | Cast rod | 525-535 | Si5 Cu28 | Brazing of aluminum and aluminum alloys. | 六、藥皮在焊接過程中起著極為重要的作用。若采用無藥皮的光焊條焊接,則在焊接過程中,空氣中的氧和氮會(huì)大量侵入熔化金屬,將金屬鐵和有益元素碳、硅、錳等氧化和氮化形成各種氧化物和氮化物,并殘留在焊縫中,造成焊縫夾渣或裂紋。而熔入熔池中的氣體可能使焊縫產(chǎn)生大量氣孔,這些因素都能使焊縫的機(jī)械性能(強(qiáng)度、沖擊值等)大大降低,同時(shí)使焊縫變脆。此外采用光焊條焊接,電弧很不穩(wěn)定,飛濺嚴(yán)重,焊縫成形很差。 | |
