Welding deformation correction method in Dongguan sheet metal processing
- 1. Reasons for welding deformation: insufficient preparation before welding, need to add fixtures, poor welding fixtures to improve the process, and poor welding sequence.
- 2. Welding deformation correction method: flame correction method, vibration method.
- 3. Welding deficiency and preventive measures: Electric welding: If the strength is not enough, bumps can be made to strengthen the welding area. C02 welding: high productivity, low energy consumption, low cost and strong rust resistance. TIG welding: shallow penetration, slow welding speed, low efficiency, high production cost, and tungsten inclusion defects, but it has the advantage of good welding quality, and can weld non-ferrous metals such as aluminum, copper, magnesium, etc.
