Brazing is a process for joining similar or dissimilar metals using a filler metal that typically includes a base of copper combined with silver, nickel, zinc or phosphorus. Brazing covers a temperature range of 900ºF - 2200ºF (470ºC - 1190ºC). Brazing differs from welding in that brazing does not melt the base metals, therefore brazing temperatures are lower than the melting points of the base metals. For the same reason, brazing is a superior choice in joining dissimilar metals. Brazed joints are strong. A properly-made joint (like a welded joint) will in many cases be as strong or stronger than the based metals being joined.

soldering is a process in which a filler metal is melted at temperatures below 840° (450° C) to form a joint between two base metals. Soldering is often used for delicate projects such as jewelry and electronics.

Answer / bishu

BRAZING:Filler material melting point temperature is greater
than 423 C......
Soldering:Filler material melting point temperature less
than 423 C

Answer / kintsho

BRAZING: THIS IS PROCESS OF JOINING TWO METALS BY HEATING AND APPLYING HARD SOLDER.BETTER CORROSION RESISTANCE


SOLDER:JOINTS DOESNOT RESIST CORROSION TO THE SAME EXTENT AS BRAZING OR WELDING

Hi everyone.. I attended the HAL interview... on 9th dec 2008 @ Bangalore.. the interview was 90% technical... my question are>>>>> 1) Design a rod that should withstand 1000N? (they told that the material is mild steel & they gave me the stress- strain graph for that) 2) what is the principal of hydraulic braking?? 3) whether interchangebility is possible between JIGS & FIXTURES??? 4) what is recent developement in Automobile ENGINE??? 5) abt my final year project (since i m a fresher) 6) some HR questions
