Container House Welding Method
The welding methods for container houses mainly include steel structure frame welding, the application of specialized welding machines, and automated welding processes. It is necessary to select appropriate techniques based on material properties and structural requirements.
I. Steel Structure Frame Welding
The framework of a container house is composed of section steels such as channel steels and columns. Channel steels (e.g., with a specification of 5×10) are used for welding the main crossbeams around the upper and lower bases. The thickness of the columns should be no less than 1mm, and they are usually shaped by professional equipment or directly purchased as finished products. During welding, it is essential to ensure that the connections between the main crossbeams and columns are full and free of cold solder joints to form a stable supporting structure. For example, in the welding of a container base, channel steels, as the main crossbeams, need to be connected to the columns through continuous welds to prevent structural cracking due to weld defects.
II. Application of Specialized Welding Machines and Processes
For different welding requirements in various parts, specialized welding machines and processes should be selected:
- Front Wall Panel Welding: The Megmeet Artsen II PM500F fully digital industrial heavy-duty MIG/MAG/CO2 welding machine is used, along with a direct current short-circuit process. This process can solve problems such as slow welding speed, unstable arcs, and excessive spatter, ensuring uniform weld formation.
- Base and Side Panel Welding: The Artsen Plus intelligent gas-shielded welding process platform welding machine is employed. Through the direct current short-circuit process, it overcomes the impact of anti-rust paint coatings on arc stability and reduces weld defects.
- Side Panel Welding: The Artsen II PM500F welding machine is also used to optimize the fusion effects of arc initiation and termination, avoiding spatter and porosity.
III. Automated and Precision Welding Technologies
In high-end manufacturing, CNC plasma cutting and fully automatic welding processes are widely used. For example, the flatness error of the top and bottom frames should be controlled within ±2mm to prevent misalignment and water leakage during lifting and assembly. In addition, automatic welding production lines certified by the International Institute of Welding (IIW) can ensure that parameters such as weld penetration and leg height meet standards, improving structural durability. For scenarios such as homestay renovations, it is also necessary to combine anti-corrosion processes such as hot-dip galvanizing or epoxy zinc-rich primers to extend the service life of container houses.
