(一)概述熔化焊过程对焊剂焊渣的熔点有一定的要求,这主要是从焊接工艺过程和冶金过程方面提出来的。一般认为其熔点应比焊丝材料的熔点低150°～300°(对于钢)或更少二些(对于较低熔点的材料)。
(A) Overview Melting process on the melting point of flux slag have certain requirements, mainly from the welding process and metallurgical processes put forward. It is generally considered that its melting point should be 150 ° to 300 ° (for steel) or less (for lower melting point materials) than the melting point of the wire material.
