Welding technology of external electric roller

Externally mounted electric roller is an indispensable metal material machine and equipment. Many parts of it are connected together by welding. The actual welding operation of the external electric roller shall be carried out according to the requirements. If you are not careful, there will be cracks, clamping and other defects. In order to prevent this defect, I explained the welding process in detail.

The external welding of external electric roller is generally divided into arc preheating welding of homogeneous (cast iron type), ultra-low temperature preheating welding of heterogeneous (non cast iron type) and arc spray welding.

1. Arc preheating welding of homogeneous (cast iron type) welding refers to the welding process of selecting cast iron type welding raw materials, preheating the whole or part of cast iron parts to 600-700 (dark red) before welding, and then carrying out welding. When the external electric roller is welded, the temperature of the weldment shall not be less than 450 degrees, and the cooling shall be slow after welding.

2. Ultra low temperature preheating welding refers to the whole process of preheating all or part of cast iron parts to 300-400 before welding. Compared with high-temperature preheating welding, the operation standard of electrician is improved, the cost of welding external electric roller is reduced, and good welding quality is obtained.

3. Different (non cast iron type) welding arc spray welding refers to the cast iron welding process of applying non cast iron type welding raw materials without preheating cast iron before welding. It has the advantages of no preheating, good standard in work, small deformation of product workpiece and convenient use.

As a relatively new type of pushing equipment, people who often use the machine and equipment should understand that the window frame of the external electric roller is mainly divided into the left window frame and the right frame. It belongs to the welding structure of thick steel plate, which is solved by cleaning the welding internal stress. The sound card frame has a lower ball bearing. There is a square screw rod in the sound card frame, and the upper part of the screw rod is fixedly connected with the bearing with seat on both sides of the upper roll.

The welding process of external electric roller can be roughly divided into the above three types. This method can also be applied when the damage needs to be repaired. Customers can also choose the welding methods suitable for economic development according to the standards in specific work.
