1. Definition of front swing and rear swing
Front swing and back swing are two swing operations commonly used in the production process of spiral welded pipes. In the production process of spiral welded pipes, after the pipe material is rolled into a round shape, the gap between the lock mouth and the sheet material needs to be accurately adjusted and controlled to ensure the quality and production efficiency of the pipe.

(1). Front swing
Front swing refers to the operation of controlling the non-joint connection between the pipe end and the sheet during the production process of spiral welded pipe. Specifically, the front swing uses manual or automatic control to move the welding part within a certain angle to maintain a certain distance between the pipe end and the sheet. This can effectively avoid adverse effects after the pipe end is docked with the sheet metal, such as weld seam pores and other quality problems.

 (2). Rear swing
Rear swing refers to the operation of adjusting the width and position of the pipe seam during the production process of spiral welded pipe. Specifically, the rear swing uses manual or automatic control to offset the gap position of the spiral welded pipe within a certain range to adjust the width and position of the pipe gap. This can make the appearance of the pipe more beautiful, and there will be less difference in the width and position of the pipe seams of the same batch of products.

(1). Different action positions
The front swing mainly acts on the pipe end of the spiral welded pipe and is used to control the connection between the pipe end and the plate; the rear swing mainly acts on the weld of the spiral welded pipe and is used to adjust the width and position of the pipe seam.

(2). Different modes of action
The front swing is to swing the pipe end to keep a certain distance between the pipe end and the sheet to avoid quality problems; the back swing is to adjust the position of the weld to make the width and position of the pipe seam meet the requirements and improve the appearance quality of the product.

 3. Summary
The front swing and the rear swing of spiral welded pipes are two commonly used operating methods in the spiral pipe welding process. Their positions and modes of action are different, but their purpose is to ensure the quality and production efficiency of spiral welded pipes. In the actual production process, it is necessary to rationally use the front and rear swing methods according to product requirements and process flow to achieve optimal production results.
