Container welding plays a pivotal role in ensuring the durability and safety of cargo transport systems. Let's delve into the various facets of container welding, material classification, and the invaluable role played by the Artsen II PM500F welding machine in improving welding efficiency and quality.
I. Container Classification and Features:
Containers, known for their versatility and ease of mechanical handling, serve as indispensable cargo containers for seamless transportation. They come in various types, each catering to specific cargo and logistical needs:
1）Types of Containers:
Classified by Cargo: general cargo containers, bulk cargo containers, liquid cargo containers, and refrigerated containers...
Classified by Materials: wood containers, steel containers, aluminum alloy containers, fiberglass containers, and stainless steel containers...
Classified by Structure: foldable containers, fixed containers (including closed-top containers, open-top containers, and flat rack containers)...
Classified by Weight: 30 tons containers, 20 tons containers, 10 tons containers, 5 tons containers, and 2.5 tons containers...
2）Materials of Containers:
Different container materials offer distinct advantages and limitations:
Steel Containers: known for their strength, structural integrity, waterproof property, and cost-effectiveness. However, they tend to be heavier and susceptible to corrosion.
Aluminum Alloy Containers: made of aluminum alloy materials, featuring lightweight, beautiful appearance, anti-corrosion, good elasticity, convenient processing and low processing and repair costs, and long service life. Yet, they are costlier and present challenges in welding.
Fiberglass Containers: made of fiberglass material, renowned for their high strength, good rigidity, large capacity, heat insulation, corrosion resistance, good chemical resistance, easy to clean, and easy to repair. Nonetheless, their weight is large, easy to age, and the strength of the screw is reduced.
3）Container International Standard Dimensions:
The present international standards comprise 13 variations: same width (2438mm), 4 kinds of length (12192mm, 9125mm, 6058mm, and 2991mm), and 3 kinds of height (2896mm, 2591mm, 2438mm).

III. The Challenges Encountered in Container Welding
A container comprises front and rear wall panels, upper and lower base plates, and left and right side panels. The manufacturing process involves the following steps as illustrated in the diagram:
The base plate is composed of 1.6mm side panels and 4mm channel steel, joined by angular welding seams using robotic welding. The client stipulates a minimum fusion depth of 1mm, a dry extension of 20-30mm, a low spatter, stable operation of the welding power source, and reliable communication with the robot.
