Effect of weldability of superalloys
The chemical composition of high-temperature alloys becomes more and more complex with the increase of temperature, so it is more and more difficult to weld. The four major factors affecting welding performance are material factors, design factors, process factors and service environment. The weldability of high-temperature alloys refers to the comprehensive evaluation of the sensitivity to cracks in the alloy, the uniformity of the tissue of the welded joints, the mechanical properties of the welded joints and the feasibility of taking process measures under a certain welding process condition.

Classification and Characteristics of Superalloy Materials
Superalloys have excellent thermal strength, thermal stability and thermal fatigue resistance. There are many types of high-temperature alloys, generally based on iron, nickel, and cobalt, adding multiple alloying elements to obtain high-temperature alloys for different purposes. Commonly used additive elements are cobalt, chromium, tungsten, molybdenum, niobium, tantalum, titanium, aluminum, vanadium, hafnium, boron or zirconium.

What are the high temperature alloy material grades
High-temperature alloy is a kind of metal material that can work for a long time under high temperature and certain stress above 600 ℃. According to the matrix elements, it can be divided into iron-based, nickel-based and cobalt-based high-temperature alloys, which are widely used in the manufacture of aviation jet engines and the hottest end parts of various industrial gas turbines.
