Container Front Panel Welding - Using Artsen II PM500F Welding Machine

Container welding plays a pivotal role in ensuring the durability and safety of cargo transport systems. The Artsen II PM500F welding machine stands out as a game-changer in this domain, specifically in welding container front panels. 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:

  1. Classified by Cargo: general cargo containers, bulk cargo containers, liquid cargo containers, and refrigerated containers...

  2. Classified by Materials: wood containers, steel containers, aluminum alloy containers, fiberglass containers, and stainless steel containers...

  3. Classified by Structure: foldable containers, fixed containers (including closed-top containers, open-top containers, and flat rack containers)...

  4. 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:

  1. Steel Containers: known for their strength, structural integrity, waterproof property, and cost-effectiveness. However, they tend to be heavier and susceptible to corrosion.

  2. 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.

  3. 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

The finished square column is constructed by welding a square tube with two plates. The plates are made of Q345 material, ranging between 32mm to 35mm in thickness, while the square tube is also of Q345 material, with a thickness varying between 12mm to 20mm. The square tube is beveled at an angle between 25° to 37°. To boost efficiency, the client attempted robotic welding. However, due to the thickness of the plates, narrow gaps, and the need for multiple layers of welding, there's been a significant lack of fusion at the base, resulting in an extremely low product qualification rate, requiring urgent resolution.

Regarding the weld seam of the front wall panel made of electro-galvanized sheet with a 2mm thickness, a specialized machine is used for welding. The client aims to further enhance efficiency by targeting a shipment output of 200 units per day. The front wall panel, being a preceding component, necessitates an increase in welding speed from 600mm/min to 900mm/min. Additionally, the seam ends must not use arc initiation boards, initiating the arc directly to complete the entire welding process, eliminating the need for subsequent arc initiation board polishing processes to meet overall efficiency requirements. Due to the influence of rust-proof paint coatings, the arc is unstable with significant spattering. The client requires well-fused arc initiation sections, flawless arc termination segments, stable arc, minimal spatter, fast welding speed with a weld seam forming excess height not exceeding 0.5mm, and a width ranging between 3 to 4mm.
