Find resistance welding equipments with the best quality at our website by browsing us.  We have a good range in resistance welding equipment to provide you with the best service. The continuous improvement after R&D lead on to the present set of resistance welding equipment available with us. The big range of resistance welding is the result of the hard work of many years with the inputs from new and existing clients which help us to make the things best in the field of resistance welding. The resistance welding is a thermoelectric process of coalescence of two surfaces when heat is produced with the resistance from the electric current and pressure lead on to joining of the surfaces. The resistance welding is mainly seven types namely, flash welding, high frequency,  percussion welding, projection welding, resistance seam welding, and resistance spot welding. The quality of our equipment is according to the international standard and every machine passed through the strict quality check by our team.

The spot welding is one of the oldest resistance welding processes where two metals are welded without the use of any filler material. The process involves the application of pressure and heat at the weld spot using the copper alloy electrode which propagates the electrical current between the two workpieces. The contact surfaces melt and the current turned off, pressure continues at the weld zone to solidify the weld zone with nuggets formation.
The principle on which spot welding developed is that when two surfaces join with pressure and passage of electric current as resistance at electrode produces heat which melts the surfaces to join and form nugget by pressure.
In spot welding, the current may be very high but the voltage is very low and this low voltage will not cause any shock. The current only flows from cathode to anode and we do not come in the path of the current. The maximum voltage for all welding equipment is 70–85 volts which are protected from electric shock.
The advantages of spot welding include ease of doing, high production, versatility for many metals, uniform joint, low-cost process, multiple welding spot at one time, automatic/semi-automatic, no trained person requirement, and no distortion of parts seen except for small indentation or depression.
Spot welding can be used for various materials including sheet metal and wire mesh. Steel is a top choice due to its low thermal conductivity and high electrical resistance. Low carbon steel is often the best option, as high carbon steels may be more brittle on the weld. Other materials such as stainless steel, titanium, and nickel alloys also work well with spot welding.
