Inconel 718 Welding mode

Inconel 718 alloy is easily welded by gas tungsten welding (GTAW), gas shielded Metal Arc welding (GMAW), shielded metal Arc welding (SMAW), electron beam (EB), and resistance welding techniques. Its welding characteristics are similar to those of HASTELLOY X alloy. Submerged arc welding (SAW) and oxyacetylene welding are not recommended, as these processes are characterized by high heat input to the base metal and slow weld cooling. These factors can increase welding constraints and promote cracking.


Base metal preparation

Before performing any welding operation, the welding surface and adjacent areas should be thoroughly cleaned with an appropriate solvent. All grease, oil, cutting oil, crayon marks, machining solutions, corrosion products, paint, scale, dye penetrant solutions, and other foreign objects should be completely removed.


Filling metal selection

Matching filler metals (AWS A5.14 ERNiFeCr-2, AMS5832) should be used to connect the Inconel 718 alloy. For welding 718 alloy to other alloys, it is recommended to use HASTELLOY® S (AMS 5838) or W (AWS A5.14 ErnIM-3, AMS 5786) to fill the wire.


Preheating and interlayer temperature

No need to preheat. Preheating is usually specified at room temperature (typical shop conditions). The interlayer temperature should be kept below 200°F (93°C). If necessary, auxiliary cooling methods may be used between passes, provided that such methods do not introduce contaminants. 


Post-weld heat treatment

Inconel 718 alloy is usually used under full aging conditions. After molding and welding, full solution annealing is usually performed prior to aging for optimal joint and overall manufacturing performance. Best practice depends on the specific conditions of manufacture prior to aging.
