sheet metal processing in sheet metal processing is bound to occur during production, except for integrally formed goods. So, what should be paid attention to before and after welding in high-precision sheet metal processing? Before sheet metal processing, you need to know welding. what types of welding are generally available

generally classified as: melting welding: argon arc welding machine, CO2 welding, steam welding, manual welding B working pressure welding: welding, butt welding, impact welding c brazing: electric chrome welding, copper wire

The following are the standard common problems of welding

1. sheet metal processing standards before welding

1. all raw materials shall not be less than those specified in the engineering drawings, otherwise they shall not be blanking and made.

2. It is stipulated that the flatness of welded channel steel shall not exceed 2/1000, and the total bending degree shall not exceed 0.3 of the total length.

3. Before welding sheet metal, the deformed parts must be straightened and straightened before welding.

4. before welding, welding rods of different sizes, specifications and models shall be used according to the size of parts, the thickness of raw materials, the size specified for welding, etc.
