Welding of Container Mobile Houses

The welding of container mobile houses mainly involves the welding of steel structural frames, requiring professional equipment and processes to ensure structural strength and stability.

1. Welding Materials and Structures

The main frames of container mobile houses are typically welded from steel materials such as channel steel and square tubes. For example, the base welding uses 5X10 channel steel as the main crossbeam, with column thickness not less than 1mm, which needs to be shaped by professional equipment or purchased as finished products. The channel steel and columns form the house's skeleton, directly determining its overall load-bearing capacity and resistance to deformation. Wall materials are mostly color-coated steel sheets or corrugated sheets, which need to be welded and fixed to the frame. Some structures use non-metallic materials such as fire-resistant floors and wooden floors, but attention must be paid to controlling the heat-affected zone during welding.

2. Welding Processes and Equipment

1. Application of Specialized Welding Machines To meet the welding needs of different parts of containers, it is necessary to select suitable intelligent welding machines. For example:

   • Front Wall Panel Welding: The Megmeet Artsen II PM500F fully digital industrial heavy-duty MIG/MAG welding machine is used, employing a direct current short-circuit process in conjunction with specialized machine welding to address issues such as slow welding speed, unstable arcs, and excessive spatter.
   • Base Plate and Side Panel Welding: The Artsen Plus intelligent gas-shielded welding platform is used, combined with a direct current short-circuit process to overcome problems such as unstable arcs and poor weld formation caused by anti-rust paint coatings.
   • Side Panel Welding: The Artsen II PM500F welding machine is also used to optimize the arc initiation and termination fusion effects, improving weld quality.

2. Process Key Points

   • Full Welding Process: Welding boxes (such as large corrugated residential containers) adopt an overall full-welding structure to ensure airtightness and durability, suitable for scenarios such as worker dormitories and temporary warehouses.
   • Deformation Prevention Control: During the welding process, it is necessary to control the heat input to avoid local overheating of the steel, leading to deformation, especially paying attention to the welding sequence and fixture fixation of thin plates (such as corrugated sheets).
   • Anti-corrosion Treatment: After welding, the welds need to be treated for rust prevention, such as spraying anti-rust paint or galvanizing, to extend the service life of the containers.

3. Welding Quality and Standards

Container mobile houses need to meet requirements such as Class A fire resistance, thermal insulation, and waterproofing, and welding quality directly affects house safety. For example, in the Beijing area, container mobile houses are required to be suitable for both winter and summer climates, with tightly sealed welds to prevent rain leakage and water seepage. In addition, the welding strength needs to comply with steel structure design specifications to ensure that the house does not experience structural failure during transportation, lifting, and use.
