The key to training novices to use tungsten electrodes correctly is to systematically explain the combination of theoretical knowledge and practical operation to ensure operating specifications and welding quality. The specific steps are as follows:
1.Theoretical Basic Training
This paper introduces the basic principles and functions of argon arc welding and tungsten electrode
Explain the characteristics and applicable scenarios of different types of tungsten electrodes
Explain the influence of welding parameters on electrode performance, such as current, electrode polarity, gas flow, etc
Emphasize safe operation precautions to prevent electric shock and harmful gas inhalation
2.Electrode Preparation And Maintenance
Teach the correct sharpening methods of tungsten electrodes and master the tip angles for different welding needs
Explain the cleaning and inspection skills of the electrode to prevent contamination and ablation
Demonstrate electrode installation, fixation and adjustment methods to ensure accurate electrode position
3.Practical Welding Operation Training
On-site demonstration of the correct arc initiation method (high-frequency arcing, contact arcing, etc.)
Guide novices to adjust the appropriate current and gas flow
Practice controlling the distance between the electrode and the workpiece to avoid electrode collision
Explain the observation of arc state and abnormal handling during welding
4.Common Problems and Solutions
Analyze common fault causes such as tungsten electrode burn-through, sticking, and arc instability
Teach how to regrind and replace electrodes in time
Emphasize the importance of protective gases and proper maintenance
5.Strengthen Safety Norms
Wear protective equipment such as gloves, face shields, and goggles
Educate reasonable ventilation and protective measures to avoid harmful smoke inhalation
Emphasis is placed on welding site safety protocols and emergency handling procedures
6.Assessment And Feedback
Through practical operation assessment, novices can master the situation
Provide targeted guidance and retraining for deficiencies
Establish operation records and maintenance files to track the usage status
