Weldability
Weldability is the ability of a metal to create a defect-free joint under certain conditions. It depends on the chemical composition and thermal behavior.
Physical-Chemical Mechanism of Action
The weldability of a metal refers to its ability to create a stable, defect-free joint under given welding conditions. This depends on the chemical composition of the material and its reaction to heat and stress.
Metallurgical Relevance & Welding Risks
A low degree of weldability can lead to defects such as porosity, distortion, or incomplete fusion. This can impair the strength and mechanical behavior of the weld.
Workshop Practice & Instructions
To ensure high weldability, it is important to choose the correct chemical composition of the metal and the appropriate welding parameters (temperature, voltage). For difficult-to-weld steels, additional deoxidation or a special welding technique may be required.
