Filler Metal In Welding

There are many types of materials used to produce welds.

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. With this type of welding the electrode is non consumable and made of tungsten. 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.

As the two objects are held together filler metal is melted between the two to create a bridge. A specialist use for filler metal is where a deliberately different metal is to be deposited. However fillet welds loaded in shear seldom require. Filler metal refers to any material used to join two pieces of metal during welding or soldering.

After the filler dries it combines with the objects on either side to create a permanent bond. Matching filler metal is typically required for complete joint penetration groove welds in tension. Filler metals for welding. Optimized efficiency with a complete solution.

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. 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. Filler metal suggestions match the base metal properties. 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.

That is the yield and tensile strength are expected to meet or exceed the minimum specified properties of the steel. Tig welding also goes by the names of heliarc and gas tungsten arc welding gtaw. 316l including er316lsi filler metal should be used with 316l and 316 base metals. Note that these filler metals cannot handle postweld heat treatment or high temperature 150 350 degrees applications.
