Filler Metal In Welding

A specialist use for filler metal is where a deliberately different metal is to be deposited.

Filler metal in welding. Cf 8m and cf 3m are the cast equivalents of 316 and 316l respectively. These welding materials are generally categorized under the term filler metals defined as the metal to be added in making a welded brazed or soldered joint the american welding society has issued 26 specifications covering filler materials. It is one of the few types of welding that can be done with no filler metal using only the two metals being welded together. Matching filler metal is typically required for complete joint penetration groove welds in tension.

Filler metal refers to any material used to join two pieces of metal during welding or soldering. Welding dissimilar metals using 309 stainless steel read article choosing the correct filler metal for mismatched base materials read article cladding of ni alloy uns n08825 in pressure vessel applications. Tig welding also goes by the names of heliarc and gas tungsten arc welding gtaw. Flux cored arc welding see gas metal arc welding fluxes see filler metals food processing systems friction welding gas metal arc welding gas tungsten arc welding gouging see cutting health see safety and health inspection laser beam welding.

Note that these filler metals cannot handle postweld heat treatment or high temperature 150 350 degrees applications. This is more like gas welding as a process but with a different heat source. There are many types of materials used to produce welds. Optimized efficiency with a complete solution.

As the two objects are held together filler metal is melted between the two to create a bridge. After the filler dries it combines with the objects on either side to create a permanent bond. Filler metal suggestions match the base metal properties. Filler metals for welding.

However fillet welds loaded in shear seldom require. 316l including er316lsi filler metal should be used with 316l and 316 base metals. That is the yield and tensile strength are expected to meet or exceed the minimum specified properties of the steel. Tig welding is an electric welding process that uses a non consumed tungsten electrode to provide heat with the filler rod added manually.
