Welding Container House Tutorial

Welding a container house requires mastering key steps such as material selection, frame welding, side and bottom plate welding, and overall assembly.

I. Material Preparation The main materials for a container house include channel steel, square tubes, corrugated sheets, fireproof flooring, wooden flooring, doors, windows, and ceiling materials. Among them, channel steel (e.g., 5×10 specification) is used for welding the main crossbeams around the top and bottom edges, similar to the ring beams of a house. Columns should be made of profiled steel with a thickness of no less than 1mm, which can be produced using professional equipment or purchased as finished products. For the chassis crossbeams, it is recommended to use 4×8×2.0 square tubes with a spacing of about 35 centimeters to ensure structural stability.

II. Frame Welding

1. Chassis Welding: Taking a 3m×6m specification as an example, the chassis is welded with 140×50 channel steel around the perimeter, and the crossbeams are made of 4×8×2.0 square tubes with a spacing of 35 centimeters, forming a grid-like support structure.
2. Column and Roof Welding: The columns and the four perimeter ring beams of the roof are fully welded with 5×5×2.0 square tubes to ensure seamless connections. The columns should be installed vertically to form a rigid frame with the chassis channel steel, supporting the entire weight of the house.
3. Welding Process Requirements: It is recommended to use a fully digital industrial heavy-duty MIG/MAG/CO2 welder (such as Artsen II PM500F) in conjunction with a direct current short-circuit process to solve issues such as unstable arcs and excessive spatter, thereby improving the quality of weld formation.

III. Side and Bottom Plate Welding

1. Side Plate Installation: The side plates are made of corrugated sheets and need to be closely fitted to the frame, with angle irons or square tubes used to reinforce the connection points. During welding, the current and speed should be controlled to prevent plate deformation.
2. Bottom Plate Welding: The connection between the bottom plate and the side plates should be fully welded to ensure airtightness. It is recommended to use an Artsen Plus welder to solve issues of unstable arcs caused by anti-rust paint coatings and improve welding efficiency.

IV. Overall Assembly and Inspection

1. Wall and Roof Panel Installation: Install the wall and roof panels sequentially on the frame, reserving positions for doors and windows. The connection points between the wall panels should be waterproofed, and the roof panels should be fully covered to prevent water leakage.
2. Door, Window, and Interior Decoration: When installing doors and windows, ensure they are tightly sealed without gaps. Inside, lay fireproof or wooden flooring and complete the pre-embedding of water and electricity pipelines.
3. Quality Inspection: Focus on checking whether the welds are firm, whether the structure is vertical and level, the airtightness of doors and windows, and waterproof performance to ensure compliance with safety standards.
