What are the specific classifications of roll welders?

The roll welder translates as concrete pile automatic wire cage welding machine. Many products are referred to simply as roll welder, such as welded steel bars, welded steel pipes, welded flanges, etc. They are collectively referred to as roll welder. There are actually more subdivided types of roll welder. We do automatic roll welder for forming reinforcement skeleton, mainly for forming reinforcement cages for precast concrete products, such as drainage pipes, inspection wells, electric poles, pipe piles, square culverts, square pole piles, photovoltaic piles, etc.

The roll welder for steel rods is widely used, especially for the manufacture of cement pipes. Among them, the roll welder for cement pipes can be divided into push rod roll welder and tie rod roll welder. The push pole roll welder is easy to operate and low cost. The tie bar roll welder is superior to the push pole roll welder in terms of roundness and aesthetics.
The pole roll welder is an integral tapered roll welder that changes the diameter by changing the threading diameter of the size die.
The circle Cage Welding Machine is an equal diameter roll welder. The welding device wraps the steel and then fixes the rotating slide for welding. The principle is the same as the pole roll welder, but one isometric and one with taper, using different dies.
The square pile roll welder is similar to the pipe pile roll welder and is a square pile roll welder after a change of mould sliding contact.
The pile welding machine for square culverts is an automatic welding machine for steel bars based on rectangular shapes. In principle it can be made horizontally or vertically for skeleton welding. The horizontal rotary roll welder is widely used in China and is less costly.
