What is the principle of steel cylinder forming spiral welding machine?

Steel barrel forming spiral welding machine is a kind of equipment used to manufacture steel barrels, using spiral welding technology. In steel cylinder manufacturing, it is usually necessary to roll the steel plate into a cylindrical shape through a plate rolling machine and then weld it. Spiral welding technology is an efficient, stable and economical welding method, suitable for the manufacture of circular or closed structures such as steel cylinders. Spiral welding technology coils the welding electrode around the steel cylinder, using high temperature and pressure to fuse the electrode with the steel plate to form a strong weld.

The working principle of the steel barrel forming spiral welding machine mainly includes the following parts:

1. Material loading and pre-bending: First, put the rolled steel plate into the steel barrel forming spiral welding machine, and feed the steel plate into the pre-bending module through the loading system. The pre-bending module will bend the steel plate into a cylindrical shape as required for subsequent welding operations.

2. Spiral welding: The bent steel plate will be fed into the welding part. The welding system will control the welding current, voltage, speed and other parameters according to the preset parameters, so that the welding arc butt welding rod coils around the steel plate. Under the action of high temperature and pressure, a strong weld is formed between the steel plate and the welding rod to complete the welding operation.

3. Post-welding treatment: The steel cylinder after welding needs to be post-processed, including cutting, shaping, weld polishing and other processes. These processes can be realized through the automatic control system of the steel barrel forming spiral welding machine to improve production efficiency and product quality.

Steel cylinder forming spiral welding machine has the advantages of simple operation, high production efficiency and stable welding quality. It is widely used in construction, bridges, petrochemical industry, transportation pipelines and other fields, bringing innovation and development to the steel cylinder manufacturing industry. At the same time, with the continuous advancement and innovation of technology, steel barrel forming spiral welding machines still have great development space and potential in terms of increasing welding speed, reducing material waste, and improving product quality.
