Rebar butt welding process
The technology of rebar end-to-end forging process was invented and developed in 1952 with the aim of using it in the rail transportation industry. With the day-by-day expansion of construction and the growth of cities and high-rise buildings, attention to the issue of retrofitting and strength of structures in order to preserve the lives and capital of residents became important, and this process entered the field of construction and construction due to the high safety factor and cost reduction.
End-to-end rebar forging welding machine:
Butt-to-butt forging welding technology of rebars is a safe and fast way to connect rebars in concrete structures of industrial and construction projects.
Strengthening against earthquakes, reducing the consumption of rebar, reducing the density of rebars and the integrity of concrete are the advantages of this easy-to-use method in all implementations of concrete structures, including foundations, walls, columns, beams, etc.
In the welding technology of end-to-end rebar forging, instead of overlapping the rebars or connecting the rebars using a mechanical patch, the two ends of the rebar are connected to each other by applying heat and hydraulic pressure.
No need for three-phase electricity, ease of implementation, high execution speed, the ability to work in all modes and the portability of the device are the advantages of this method.
This method is used in connecting foundation rebars, column rebars, bolt rebars, pile rebars, wall rebars, broken rebars, waste rebars.
The advantages of butt forging welding of rebars:
• Saving up to 30% in the consumption of rebar by removing overlaps and gaps.
• Reduction of time, manpower, transportation due to reduction of consumption.
• Connecting unusable (discarded) rebars to each other and reusing them.
• Due to the reduction in the consumption of rebar, the main weight of the structure is reduced and correspondingly, the lateral gravity forces are also reduced, and as a result, the structure's resistance to earthquakes will increase.
• This system greatly reduces human errors (it has been observed that the executive personnel reduce the length of the overlabs to reduce the overhang of the rebars, which reduces the resistance of the rebars at the connection points and, as a result, reduces the strength of the structure.)
• Due to the reduction of the excess volume of the rebars at the connection points, the possibility of better vibration, which has been a very important problem until now, will be solved and a better and more suitable vibration will be possible.
• Due to the reduction of the additional volume of rebars, the engagement of concrete with rebars will increase.
• Increasing the resistance at the connection point, so that the resistance at this point is higher than at other points along the length of the rebar.
• Maintaining the metallurgical properties of the rebar.
• The ability to make a connection, with minimum root length
• Maintaining the integrity of load analysis at the junction
• Has technical approval from the building and housing research center
