The cause of welding deformation in sheet metal processing and the correction method
Welding symbols in sheet metal processing are divided into delta angle welding, type I welding, type V welding, V-type welding (V) with blunt side V-type welding (V), spot welding (0), plug welding or groove welding (II), coiling welding (V), blunt U welding, blunt J welding, bottom seal welding, and welding.
The above is about the type of welding in sheet metal processing. How did the deformation cause in the welding process? What if it's going to be solved? We wait and see:
1. cause of welding deformation: insufficient preparation before welding, increase fixture, bad welding jig, and poor welding sequence.
2. welding distortion correction method: flame correction method and vibration method.
3. welding defects and preventive measures: electric welding: not enough strength to bump, strengthen welding area. C02 welding: high productivity, low energy consumption, low cost and strong rust resistance. Argon arc welding: the melting depth is shallow, the welding speed is slow, the efficiency is low, the production cost is high, it has the tungsten defect, but it has the advantage of good welding quality. It can weld non-ferrous metal, such as aluminum, copper and magnesium.
