Filler Metal In Welding

Filler metal refers to any material used to join two pieces of metal during welding or soldering.

Filler metal in welding.

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. Matching filler metal is typically required for complete joint penetration groove welds in tension. Tig welding is an electric welding process that uses a non consumed tungsten electrode to provide heat with the filler rod added manually.

Use 309l including er309lsi when joining mild steel or low alloy steel to stainless steels for joining dissimilar stainless steels such as 409 to itself or to 304l stainless as well as. Filler metals for welding. Filler metal suggestions match the base metal properties. 316l including er316lsi filler metal should be used with 316l and 316 base metals.

When welding 6xxx series the 5356 filler metal offers good cracking resistance and strength excellent ductility acceptable corrosion resistance excellent color matching capability after anodizing and excellent toughness. With this type of welding the electrode is non consumable and made of tungsten. 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. However fillet welds loaded in shear seldom require.

Optimized efficiency with a complete solution. Cf 8m and cf 3m are the cast equivalents of 316 and 316l respectively. As the two objects are held together filler metal is melted between the two to create a bridge. 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.

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