Filler Metal In Welding

Tig welding also goes by the names of heliarc and gas tungsten arc welding gtaw.

Filler metal in welding.

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. Matching filler metal is typically required for complete joint penetration groove welds in tension. 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. 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.

However fillet welds loaded in shear seldom require. Note that these filler metals cannot handle postweld heat treatment or high temperature 150 350 degrees applications. A specialist use for filler metal is where a deliberately different metal is to be deposited. Filler metal suggestions match the base metal properties.

Tig welding is an electric welding process that uses a non consumed tungsten electrode to provide heat with the filler rod added manually. Optimized efficiency with a complete solution. 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. Filler metal refers to any material used to join two pieces of metal during welding or soldering.

This is more like gas welding as a process but with a different heat source. Filler metals for welding. 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. There are many types of materials used to produce welds.

As the two objects are held together filler metal is melted between the two to create a bridge. 316l including er316lsi filler metal should be used with 316l and 316 base metals. With this type of welding the electrode is non consumable and made of tungsten. After the filler dries it combines with the objects on either side to create a permanent bond.
