Blending joints between bridges & roads, food making & catering vessels, assembling a train, plane, and automobile needs a  fastening method. The technique demands hole-free, leak-free, and decorative procedures that are possible by a stud welder.

It is a very popular method for its speed, accuracy, reliability, and aesthetic looks. It fastens the stud effortlessly and achieves the joint strength more than the base metal.

The selection of one from the list of available equipment is not an effortless task. We will make this process of shopping easy and complete your project in stipulated time with minimal cost and best of quality.

Stud Welding Process

It is better to start the discussion, what is stud welding? 

A single-sided fastening technique that joins two metals. The fusion is by a strong electric arc that melts both surfaces, fastener, and base metal. Pressure and cooling of the molten pool lead to a strong lifetime stud joint. 

Benefits offered – The list of advantages is as follows:

Physical appearance – Fastening is carried on one side of metal, leaving no or minimal mark on the backside. This invisible welding is easy on the eye but highly secure and favored.

Versatile – Useful for metals like stainless steel, mild steel, copper, aluminum, and brass. You can adopt studs like threaded, internally threaded, unthreaded, and the diameter may range from 1 to 25 mm.

Approachable & accessible – One-sided process makes it maneuverable to weld in hard to reach areas. The welder needs not to buckle himself to make a secure effective weld thus makes it an accessible process.

Hole-free – No need to make any hole to fasten the stud. It makes the process clean and removes the chance of leaking and weakening of the sheet. The leak-free process prevents corrosion and makes it neat, clean & durable.

Pace – A quick fastening method that can deploy for a large scale project. The machine can weld up to eight studs per minute manually. The process can be automated fully or partially. The automation can be in the entire process or for a certain stage of the project as per the requirement for speed, accuracy, appearance, and budget.

Ease – The process is very easy to master, even a novice can perform with this equipment comfortably with excellent results.

The shape of parent metal – No distortion is seen to the base/parent metal in the welding process.

Labor cost – It reduces drastically as the process of pre-drilling, punching, and riveting is omitted here. The process becomes fast and reduces the cost of the project.

Types of Stud Welding Processes

Arc Stud Welding/Drawn Arc Stud welding

CD Stud welding/Capacitor Discharge Stud Welding

Drawn Arc Stud Welding

It is the most dependable fastening technique for the industries. It is a quick method to fasten any size or configuration of studs to a metal workpiece. The penetration is maximum to make the weld joint strong and reliable.

One-sided strong weld is imaginable with the base metal as thin as 0.048 inches and as fast as 0.06 second. A strong arc of stud welding is a possibility with DC power source, stud gun, metal stud, and ferrules sometimes. The ferrule is a disposable ceramic shield to contain the pool of molten metal.

stud gun

A metal stud is loaded in the chuck of the stud gun welder and a ferrule is placed at the end. It is time to plant the stud gun against the workpiece and press the trigger. DC supply on triggering signals the internal lift system of the gun to energize. It is time to lift the gun and draw the pilot arc. This arc makes up a path for the weld current. Complete the arc time which is directly proportional to the square area of surface need to be melted. 

The completion of the arc time makes the lift system de-energized and plunges the stud in the pool of molten metal. You may need a plunge speed stabilizer to decelerate the stud to minimize the splash. The metal stud and base metal solidify to and create a solid welding zone. Lift the stud gun welder and discard the ferrule used in the process.

The metal stud is embedded with flux, after vaporizing reacts with contaminants in the atmosphere to keep the welding zone clean.

Drawn Arc Stud Welding Advantages

  • There is a full cross-sectional weld to make the weld zone stronger than the base metal.
  • Vibration-proof weld resists from loosening, breaking, and weakening of the weld joint.
  • One-sided weld gives the engineer a design versatility and cosmetic appeal because the backside of the base metal is not marred even.
  • A fast and easy process as it avoids drilling, punching, tapping, and riveting.
  • Low labor costs as a single worker can complete the process.
  • Economical fabrication method to erect by duplicating the technique for a structure.
  • One can do the stud welding on painted surfaces by a small amendment.

Capacitor Discharge Stud Welding (CD Stud Welding)

We design capacitor discharge stud welding to weld small-diameter, lightweight, thin metal sheets. It is possible to complete the weld cycle in 0.01 seconds on the thin metal up to 0.02 inches. The speed of the weld has minimum heat buildup leading to very little distortion, burning, and discoloration of base metal. They designate this method for a project when appearance is a critical feature.

Cruxweld CD Stud Welder

CD stud welding uses a storage system of a capacitor to generate a rapid electrical discharge. The fastening process is wonderful for mild steel, stainless steel, and aluminum. We do not use here flux or ferrules. The stud welder kit is an essential part.

To initiate CD stud welding we load a stud in the stud gun welder and position it against the workpiece. The stored energy of the capacitor is discharged instantaneously through the projection of the stud. The current density is so high to vaporize the tip and create a gap that allows an arc production. This hot arc melts the stud and mother metal and then two pieces are forced together to make a joint on cooling.

As the technique produces minimal marking on the backside, it is suited best for cosmetic applications.

CD Stud Welding Advantages

  • High integrity welding on thin gauge metal sheets.
  • It can weld dissimilar metal without many metallurgical issues.
  • Attractive joint with a minimal burn.
  • One-sided welds without reverse side dimples.
  • Cosmetically acceptable method.
