What is the formula for weldability?

The most common carbon equivalent (CE) formulas to evaluate weldability depends if the metal is an alloy steel or modern carbon steel. Here are both common CE equations; for low alloy steel, elements are expressed in weight percent amounts; CIIw = C + Mn/6 + (Cr+Mo+V)/5 + (Ni+Cu)/15.See all results for this questionWhat is Ni-base weldability?The ability of Ni-base alloys to be joined by welding processes and to perform as intended in their service environment describes their weldability. Testing procedures are available that can evaluate weldability so that proper material or process selection can be implemented during fabrication and repair.See all results for this questionWhat does weldability mean?A simple definition of weldability is the ability to be welded without cracking. A simplistic definition, but good enough for many situations. In general, as the CE increases there is more concern for cracking due to decreases in ductility (as strength and hardness increase, ductility decreases) and increased potential for cracking.See all results for this question

Welding of Nickel Alloys

Nickel alloys can be joined reliably by all types of welding processes or methods, with the exception of forge welding and oxyacetylene welding. The most widely employed processes for welding the non-age-hardenable (solid-solution-strengthened) wrought nickel alloys are gas-tungsten arc welding (GTAW), gas-metal arc welding (GMAW), and shielded metal arc welding (SMAW).Welding of Nickel Alloys - Part 1 - TWIAlthough weldability of nickel and its alloys is generally good the composition, metallurgical structure and its heat treatment and/or service history all affect its response to welding. Wrought, fine grained components have better weldability than cast items as these often have significant amounts of segregation. Coarse grains may lead to micro-fissuring in the HAZ thus high heat input is best avoided. All the alloys are best welded in the annealed or solution treated condition and this applies particularly tSee more on twi-global weldability of niWelding Metallurgy and Weldability of Nickel-Base Alloys weldability of niWelding Metallurgy and Weldability of Nickel-Base Alloys describes the fundamental metallurgical principles that control the microstructure and properties of welded Ni-base alloys.
