Gas pressure welding of rebar process
Gas pressure welding of rebaris one of the methods in oxy acetylene welding in which the rebars reach getting-pastytemperature )1,200-1,300 degrees centigrade),without melting the base metaland any additives, tip-to-tip by the heat resulting from oxyacetylene flame and get connected to each other by the pressure resulted from hydraulic cylinder)RAM)
Molecules of two welded surfaces transfer to each other without any changes in structure and mechanical properties. Reinforce bar is steel witch is mixed by atom of iron and carbon
Atom of them in steel stable at normal temperature and they are making regular arrangement.
Gas pressure welding stick each reinforce bar by their join of crystal
Then we used heat to make rearrangement of each atom easily at each reinforce bar joining
Both atom start to move actively by heating at once and also change structure crystal as before then diffuse. It means they start to be mixed of each atom
Why Gas pressure welding of rebar
A lack of enough stabilityat the location of connection and increased density in some areas caused some traditional method of rebars’ overlapping to be replaced by (coupler) mechanical connections method and this method was not welcomed due to making delay in project advancement scheduling (due to time-consuming preparation and execution as well as high costs) at the onset and was not limited to be used in special projects
Gas pressure welding is a very proper method and good replacement instead of overlap traditional method and mechanical connections method as the latest method in buildings components with an easier, faster, cheaper and higher stability
Gas pressure welding can save your cost and quantity of reinforce bar at your site definitely
Advantages of gas pressure welding
Increased resistance in connection point due to increased diameter
30% save in rebar consumption
Reduced human errors in rebar binding and layout of rebar
Weight reduction in structure due to overlap elimination
Increase in structure resistance against external forces (earthquake etc.) due to weight reduction in structure and a reduction in gravity force
Increase in concrete mix with rebar due to a decrease in rebar dimensions
The possibility to a better and more ideal vibration due to a decrease in volume of reinforcements
A reduction in areas and consumption of concrete and a reduction of dead space under the building (in pillars)
Maintenance of integration of bar’s certificate of analysis in connection point
A reduction in transportation costs due to a reduction in consumable materials
Ability to create a connection with at least 10 cm reinforcement length
Preservation of rods’ metallurgical properties
The possibility to connect different sizes (according to standard) to each other
High execution pace with the least expense and time-waste prevention of reinforcing executive personnel
The possibility to connect scrap rebars
Usability in all circumstances including columns, shear walls, beams, foundation etc
Lack of need to high-voltage electricity
Comfortable application and portable by human
