What is sheet metal fabrication welding?
We- one stop sheet metal fabrication manufacturer will tell you in details following:
A.What is sheet metal fabrication welding?
Sheet metal fabrication welding is to weld multiple sheet metal parts together to achieve the purpose of processing or weld the edge seam of a single part to increase its strength. The welding methods are generally as follows: argon arc welding, spot welding, etc.
B. What is the general welding method for sheet metal fabrication welding?
The selection of sheet metal fabrication welding methods is based on actual requirements and materials. Generally speaking, argon arc welding is used for aluminum plate and stainless steel welding. Galvanized plate and the like are adequately welded with CO2 welding. Resistance welding or pressure welding is used for bolts and nuts welding.
C. The advantages and disadvantages of sheet metal fabrication welding processing
1.The benefits of sheet metal fabrication welding
1) Save materials and reduce structural weight;
2)Simplify processing and installation procedures and improve production efficiency;
3)High structural strength and good joint sealing; provide greater flexibility for structural design;
4)The welding process is easy to realize mechanization and automation;
2.Disadvantages of welding
1)The simple welding structure leads to larger residual deformation and welding internal stress. Because most of the welding methods use partial heating, the welded parts after welding will inevitably undergo stress and deformation in the structure, which will affect the layout bearing capacity, processing accuracy and dimensional stability. At the same time, stress will be concentrated at the junction of the weld and the weldment, which will affect the brittle fracture of the structure;
2)There are simply a certain number of shortcomings in welded joints: such as cracks, pores, slag inclusion, incomplete penetration, and incomplete fusion. Disadvantages will reduce the strength, cause stress to gather, and damage the fineness of the weld;
3)The welded joint has a large functional unevenness, because the composition and metallographic structure of the weld are different from the base material, and the internal stress of each part of the joint is different, which makes the performance of the joint in different places different;
4)High temperature, strong light and some toxic gases occurred during welding, which are harmful to the human body, so labor protection should be strengthened.
