Weld Start Detection
Automatic detection of the start of a weld seam by sensors prevents misfiring and improves accuracy.
Physical-Chemical Mechanism of Action
Weld start detection uses sensors to identify the beginning of the weld joint. These sensors react to specific physical or chemical changes in the environment, like temperature rises or metal deformation.
Metallurgical Relevance & Risks in Welding
Mis-starts outside the joint can lead to incomplete welding, porosity, and reduced mechanical properties. Detecting the start of the weld minimizes these risks and ensures a clean and efficient weld joint.
Workshop Practice & Instructions
To implement weld start detection, make sure the sensors are properly calibrated and placed near the welding torch. The exact position and type of sensors vary depending on the welding process used (e.g., TIG, MIG). If issues occur, check the sensors for correctness and stability.
