Container House Welding Technology

Container house welding technology mainly involves the welding of steel structural frames, the application of specialized welders for different parts, and the control of key process parameters.

Welding of steel structural frames is the foundation of container houses. Their frames are usually welded from profiled steel. For example, channel steel is used to weld the main crossbeams around the top and bottom of the container, similar to the ring beams in house construction. The thickness of the columns is generally not less than 1mm, and they need to be profiled using professional equipment or purchased as ready-made products. Channel steel and columns form the entire skeleton of the house, playing a decisive role in its sturdiness. During the welding process, it is essential to ensure that the steel thickness of the main beams and columns meets the standards and that the welding process is full without cold solder joints to guarantee the safety of the container house during lifting, stacking, and transportation, as well as its service life.

Specialized welders and processes are used for different parts. For example, the Artsen II PM500F welder is applied to the welding of the front wall panels and side panels of container houses, using a direct-current short-circuit process in conjunction with specialized machine welding. This solves problems such as slow welding speed, unstable arcs, excessive spatter, and poor weld formation. The Artsen Plus welder is applied to the welding of the bottom panels and side panels of container houses, also using a direct-current short-circuit process, which addresses issues such as unstable arcs, poor weld formation, and excessive spatter caused by the influence of the anti-rust paint coating.

Controlling key process parameters is crucial. In terms of structural accuracy, the key aspects controlled within the industry are weld penetration, leg height, and diagonal errors of the container body. For example, the packing container houses produced by Guoheng use CNC plasma cutting and fully automatic拼焊 (here '拼焊' is translated as 'butt welding' in a general sense, but a more precise term might be needed based on the specific context; for now, we keep the process description) processes. The flatness error of the top and bottom frames is controlled within ±2mm, eliminating the risk of misalignment and water leakage during the lifting and assembly of民宿 (translated as 'homestay' here, adjust if a more specific term is needed) container bodies.
