Q&A: What factors should be considered when selecting the groove type? Correct answer: The main factors are as follows: 1. It ensures full penetration ； 2. Ensure the possibility of welding ； 3. The groove is easy to machine ； 4. Improve productivity as much as possible ； 5. Try to save welding materials and reduce the consumption of labor hours ； 6. Reduce deformation
(1) Ability to ensure full penetration (2) Feasibility of welding (penetration of the electrode, approach of the welding torch) (3) Ease of groove preparation (4) Maximizing productivity
(1) Whether it can ensure full penetration of the welded joint; (2) Whether the shape of the groove is easy to machine; (3) Productivity should be improved as much as possible to save filler metal; (4) The deformation of the welded joint after welding should be minimized.
