Since the energy of arc burning during Hexagon Socket Head Bolt welding is concentrated between Hexagon Socket Head Bolt and the base metal and their melting zone, a certain pressure must be applied in the melting zone during Hexagon Socket Head Bolt welding. The pressure at this time is quickly and accurately obtained after the arc burns, and there is no pulsation. After a short welding time and peak current, under pressure, the end of the Hexagon Socket Head Bolt is immersed in the molten pool, and the liquid metal part is extruded out of the joint to form a welded joint, which makes the application of stud welding There are many characteristics.

Characteristics of stud welding machine

Very time and cost saving

  All stud welded structures do not require drilling, punching, threading, riveting, screwing and finishing.

2. The expanding application potential of structural design

  When the stud welding machine is used, the welding process is short time, large current and small penetration. Therefore, it can be welded to a very thin plate. For the use of ceramic ring drawn arc stud welding (stud welding machine) and short-cycle drawn arc welding, the plate thickness can be up to 1mm. Capacitor discharge arc stud welding can reach 0.6mm, while capacitor discharge tip ignition stud welding can reach 0.5mm.

  Stud welding workpieces must be welded from one side.

  It can be welded at all positions, and it can be welded to the restricted vertical partition by means of the expander.

  Because it is welded for a short time and rarely deforms after welding, no trimming is required.

  Stud welded joints can achieve high strength.

  After the plating or high alloy plate is welded, there is no mark on the back.

3. Good economy

  The advantage of stud welding over other welding methods lies in the welding power. For mass-produced workpieces, it can reach 8-40 pieces / min in a short welding time (3-980ms) (according to different diameter studs and different welding power). The automatic feeding stud welding machine can reach 60 pieces / min.

  Standard studs are low cost.

  There are many types of stud welding equipment and welding guns, and the equipment purchase cost is relatively low.

  Depending on the product, it can be made into a multi-station automatic welding machine, or a high-precision gantry CNC automatic welding machine.

  Stud welding has higher quality reproducibility and smaller scrap rate.

  However, the application of traditional Chinese medicine in stud welding is to note that stud welding, like other fusion welding, has restrictions on the carbon content of steel-for structural steel studs, the carbon content w (C) should be 0.18% Within; and the carbon content w (C) of the base metal should be within 0.2%.

  According to the different methods of stud welding, the recommended stud material and base metal combination are weldable: otherwise the stud and base metal will be insoluble with each other.

  The combination of stud material and base material beyond the recommended range shall be determined by experiment to determine the weldability and the possibility of relevant inspection and evaluation according to the design requirements of the product.
