Excessive weld reinforcement
Excessive weld reinforcement is caused by too much weld metal, which leads to unnecessary material consumption and sharp notches. This affects toughness and mechanical strength.
Physical-Chemical Mechanism of Action
Excessive weld reinforcement occurs when, during the welding process, too much weld metal is deposited on the surface of the weld. This leads to an excessive buildup of metal in the weld.
Metallurgical Relevance & Risks in Welding
This excess can cause sharp notches to the base material, which impairs the mechanical strength and toughness of the weld. Additionally, it increases material consumption and can lead to visual defects.
Workshop Practice & Instructions
To avoid excessive weld reinforcement, control the welding speed and weld volume. Use an appropriate welding process and parameters. With high-performance processes like TIG or MIG, it is especially important to optimize gas flow and electrode positioning.
