Sensor-Based Gap Measurement

Sensor-based gap measurement continuously captures the joint gap width and adjusts the heat input to avoid burn-through or insufficient root formation.

Physical-Chemical Mechanism of Action

Gap measurement measures the gap width before welding and sends this information to a control unit. This unit regulates the heat input to ensure optimal penetration.

Metallurgical Relevance & Welding Risks

Inaccurate gap measurement can lead to too high or too low heat input. Too little heat causes lack of penetration, too much heat can cause overheating and distortion of the workpieces.

Workshop Practice & Action Guidelines

Use high-precision sensors to measure the gap width. Make sure the sensors are correctly calibrated and positioned near the gap. Regulate the heat input based on the measured values to ensure a defect-free weld.
