Difficulties of welding
Welding incolloy associated with a number of difficulties due to the fact that the transition metal from solid to liquid there is a tendency to formation of pores. In arc welding in argon protective environment, the main source is nitrogen. After cooling of the weld, gaseous nitrogen forms pores inside the metal.
Welding Incoloy carries a high tendency of the seam to the occurrence of crystallization cracks at the boundaries of large grains, which have a transcrystalline structure. To prevent the occurrence of cracks, it is necessary to limit the content of harmful impurities and to introduce elements that bind the sulfur, the most refractory compounds.

Optimization of welding
An important condition is cleanliness of the surface of welding materials and basic metal and hydrogen binding. This is solved by the introduction of strong deoxidizers in the weld pool (titanium, aluminum, etc.), as well as the use of coatings or fluxes, which are able to transfer hydrogen in the persistent volatile compounds.
