STUD 2500 WELDING MACHNEStud Welding - Overview
Stud welding is a complete one-step fastening system, using fasteners called weld studs. Weld studs come in a variety of designs, threaded, unthreaded, tapped, etc., sizes and shapes for a wide range of applications.
Examples of Weld Studs for various applications
A weld stud can be end-joined to a metal work piece instantaneously for a high quality, high strength permanent bond. (View video demonstration.)
The base metal and the welded stud fastener do not need to be the same material. For example these combinations can be welded together - brass to copper, brass to steel, copper to steel and similar combinations.
Stud welding is less expensive than other fastening methods and can used in locations which do not allow the use of other fasteners. Weld studs can be installed by one man, working on one side of the work piece, in less than a second.
There are many reasons why the stud welding process is superior over other fastening systems.

Stud Welding, more correctly termed drawn arc stud welding, is an electric arc process that rapidly joins a fastener to a base metal or substrate. The fastener can take many forms: threaded, unthreaded, tapped etc. Both the fastener and the substrate can be of various materials including: steel, stainless steel, aluminum etc.

The advantages of stud welding machine is welding strength which is more than the surrounding metal, no filler wire requires making it economical, production is very high, one-sided fastening gives ample space for designing, a semi-skilled person may operate the machine and cost of operation are reduced to the lowest.Stud welder is used in a process where a metal stud is welded by the heating process of the arc to the workpiece. There happens to be a strong one-sided welding on base metals of different thickness from 3 mm to 25 mm. This process is the most reliable method of fastening to any size and configuration of stud welded quickly to the workpiece and provides high welding penetration and stability. The welding set is 50% lighter in weight as compared to the transformer type, the energy consumption is half than the traditional machines, the efficiency degree is high as it is inverter technology.What we do in stud welding is put the positive pole of power source on the workpiece. The required stud inserted into the stud welding gun to a position on the workpiece may be with ceramic ferrule to position it. We can start the welding process by lifting the stud. When stud lifted the low arc or pilot arc is drawn. The main arc produces between workpiece and stud. The ampere is adjusted as per diameter and cross-sectional area. At the completion of welding time, the stud is directed toward the workpiece. Now turn off the power source thus welding zone is cool down and solidify.
