Welding Construction Technology of Membrane Structure Automobile Shed

According to the construction process and characteristics of custom space steel structures, the main construction techniques can be summarized in the following aspects: hoisting; Welding; Component approach, acceptance and stacking; Selection, arrangement and disassembly of the crane; Measurement control; Construction period and quality control; Safe construction, etc. The following membrane structure supplier will specifically analyze the construction technology of its welding process:

(1) confirmation of welding sequence:

The order of welding in the plane shall be confirmed from the center to the edge of the membrane structure plane, and attention shall be paid to the structural symmetry, the symmetry of the nodes and the order of the whole direction during the welding process. The welding sequence for the vertical interior is as follows: upper frame beam → pressing steel plate support → lower frame beam → pressing steel plate support → welding inspection. The welding sequence between column and beam joint is: lower flange plate of h-beam → upper flange plate of h-beam → one end of beam → the other end of beam. The welding between column and column can be carried out before or after the beam welding, and the welding between column and column should be carried out on both sides of the isothermal, isothermal symmetry and at the same time.

(2) welding process:

The confirmation of welding process is mainly to confirm the gas used in the welding and the welding method used. The welding process is closely related to the quality of the steel structure of the membrane structure of the automobile shed during the construction. The confirmation of welding process is mainly based on the thickness of the steel plate, the structure and the conditions of the construction site.

(3) confirmation of welding parameters:

After confirming the welding process of membrane structure automobile shed, the welding quality control department needs to evaluate the process and work out a set of feasible welding methods and parameters. Analyze the system, confirm the target to find out the reasons affecting the quality and the corresponding countermeasures and measures; Carry out repeated tests to confirm the corresponding process parameters; Through the extension length of the welding wire, the welding seam layer cleaning, welding gun welding Angle for repeated exploration summary.
