Soldering Process
​
The joining of metals using a filler metal
of a lower melting point
Soldering Process:
The joining of metals using a filler material of a lower melting point than that of the parent metals to be joined.
​
Key Benefits of Soldering:
-
Produces smooth, favorable appearance than a welded joint.
-
Low power is required.
-
Low process temperature.
-
Microstructure is not affected by heat.
-
Easily automated process.
-
Dissimilar materials may be joined.
-
High variety of materials may be joined.
-
Thin wall parts may be joined.
​
Applications:
-
Electronics/Electrical, aerospace, automative, HVAC/R, construction, fine jewellery
​
Soldering vs Brazing:
-
Soldering - The filler metal used has a liquidus below 840F (450C) and below the solidus of the base metals.
-
Brazing - The filler metal used has a liquidus above 840F (450C) and below the solidus of the base metals.

IS 2927: BaCuAg15
DIN 8513: L-Ag45Cd
DIN EN 1044: AG302
AMS: 4769
Key Benefits:
-
Suitable for use on most metals except aluminum and magnesium
-
Used for joining steel, stainless steel, copper, copper alloys, nickel, nickel alloys or combinations of these metals.
-
Has a narrow melting range which is not apparent in most brazing operations, making it flow freely through capillary action.
