合金刀头用什么焊接更好?
都是用铜焊,强度不是太高,如果需要更好的焊接效果,可以考虑用MG130 ,流动性好,易操作,强度高,要高一倍呢.达到7000psi(483MPa)
MG130
\x05Super strength,general use brazing rod.
\x05Excellent for over laying and build-up at low temperatures(760~780℃).
\x05Excellent for close fitting joints,thin-flowing at high temperatures (900~955℃).
\x05Designed to build-up or join carbon steels,alloy steels,cadt iron,and many non-ferrous materials.
\x05For uses such as:
-gear teeth build-up -attaching carbide cutting tips
-bulid-up of bearing shafts -joining bicycle assemblies
-brazing of rusty surfaces -heavy equipment repair

For best results,use a neutral flame.
Hints
\x05Rough-grind surfaces prior to brazing.
\x05Use neutral flame concentrated on the base metal,not on the alloy.
\x05To prevent overheating,keep torch in constant motion.
\x05Additional passes can be made without removing flux residue from previous passes.Allow part to cool slowly.
\x05Excellent for losing gaps or building-up worn areas such as bearing seats,chipped gear teeth,etc.
