NILOR CF42 焊絲

NILO CF42 焊絲主要用于NILO 42合金的熔化極氣體保護(hù)焊、鎢極氣體保護(hù)焊和埋弧焊。NILO CF42 填充金屬與NILO 42合金一樣具有較低的熱脹特性，這防止的了凝固裂紋和再熱裂紋的產(chǎn)生。當(dāng)這種焊絲用于噴射過渡的GMAW焊接過程時(shí)，推薦使用氬氣作為保護(hù)氣體；當(dāng)用于GMAW脈沖焊接和短弧焊接時(shí)，推薦使用氬氣和25％氦氣混合氣體作保護(hù)氣；當(dāng)用于SAW焊接時(shí)應(yīng)當(dāng)使用INCOFLUX 6焊劑。

直焊絲的長度為：915mm(36”)或1000mm(39”)

NILO CF42 electrode is mainly used in the welding of the melting electrode of NILO 42 alloy, the welding of tungsten electrode gas and the submerged arc welding. The NILO CF42 filler metal has the same low thermal expansion properties as NILO 42 alloy, which prevents the production of solidified cracks and reheat cracks. When this wire is used for the GMAW welding process of spray transition, argon is recommended to protect the gas. When used for GMAW pulse welding and short arc welding, it is recommended to use argon gas and 25% helium mixture to protect gas. INCOFLUX 6 flux shall be used when used for SAW welding.
