What is the difference between a regular iron can and a welded iron can?

Ordinary iron cans and welded iron cans are two different products, and there are some significant differences between them. Below we will detail the characteristics and differences of these two types of iron cans.

1. Ordinary Iron Can

Ordinary iron cans are generally made from thin steel plates or iron sheets, produced through processes such as rolling, cutting, and forming to create the can body, and then using sealing techniques to securely attach the lid to the can opening. These iron cans typically have good sealing performance, effectively protecting the internal items from external environmental influences. Ordinary iron cans are widely used in food, pharmaceuticals, chemicals, etc., such as tea cans and candy jars.

2. Welded Iron Can

Welded iron cans are made from thicker steel plates through welding processes. The various parts of this type of can (such as the bottom, lid, walls, etc.) are connected together by welding techniques to form a whole. Welded iron cans have a higher load-bearing capacity and pressure resistance; therefore, they are usually used for storing heavier items or liquids. In addition, welded iron cans also have high sealing properties and corrosion resistance, making them suitable for various harsh environments.

3. Main Differences Between the Two

1. Manufacturing Process: Ordinary iron cans mainly use rolling and sealing processes, while welded iron cans use welding processes.
2. Material Thickness: Due to different uses, welded iron cans typically use thicker steel plates while ordinary iron cans use thinner steel plates or iron sheets.
3. Performance and Use: Welded iron cans have a higher load-bearing capacity and pressure resistance suitable for storing heavy items or liquids, while ordinary iron cans are more suitable for storing solid items such as food and pharmaceuticals.
4. Appearance: Due to differences in manufacturing processes, ordinary iron cans and welded iron cans also differ in appearance. Ordinary iron cans usually have a smooth surface with clear patterns while welded iron cans may show some welding marks at the seams.

In summary, ordinary iron cans and welded iron cans have obvious differences in manufacturing processes, material thicknesses, performance and uses as well as appearances. Consumers should choose the appropriate type of can based on actual needs and usage environments.
