What is tip dressing spot welding?

Tip Dressing Tools for Spot Welding Repeated exposure to high temperature and pressure alters copper electrode tip geometry over a number of welds. Tip dressing resets the electrode shape to help your company meet the precise specifications of your customers.

What is robot tip dresser?

In automatic tip dressing, a tip dresser is mounted on the line where it can be accessed by the welding robot. The robot is programmed to dress the electrodes at regular time intervals. The dressing can be done after each working cycle, after every second cycle, and so on.

How does Spot welding work?

Spot welding works through conductive heating, which is created by an electrical current. Classic spot welding positions two copper alloy electrodes, which hold the two pieces of metal together. The electrical current flows through the electrodes, creating concentrated heat to melt the metal.

What are spot welding tip made of?

Electrode tips for RW are made from various copper alloys, selected to suit the application, with the most common being RWMA Class 2, an alloy of copper and chromium.

Is it easy to spot weld?

Due to its lower thermal conductivity and higher electrical resistance, steel is comparatively easy to spot weld, with low carbon steel being most suited to spot welding. Galvanised steel (zinc coated) requires slightly higher welding currents to weld than uncoated steels.

What are spot welders good for?

Spot welding is used for welding overlapping pieces of metal through pressure application and supplying an electric current to the metals that need to be welded together. The welding electrodes are made of copper for its good conductive ability.

Is spot welding hard?

Spot welding is quick and easy. There is no need to use any fluxes or filler metal to create a join by spot welding, and there is no dangerous open flame. Spot welding can be performed without any special skill.

Why do you need a tip dresser for welding?

Proper tip dressing helps maintain weld consistency and quality in spot welding applications while also saving time and money. Robotic tip dressers with dual-sided sharpeners/shapers for resistance welding electrodes — are generally mounted on stationary stands for robotic weld gun arms…

Where do you place a robotic tip dresser?

Robotic tip dressers with dual-sided sharpeners/shapers for resistance welding electrodes — are generally mounted on stationary stands for robotic weld gun arms and on retractable swing arms for pedestal welding units. Repeated exposure to high temperature and pressure alters copper electrode tip geometry over a number of welds.

Which is the best electrode tip dresser to buy?

Kyokutoh’s “Stingray” Electrode Tip Dresser (New ETD) can help you achieve better, more consistent welds, without a tiring and labor-intensive routine.

Which is a faster alternative to manual weld cap changes?

The faster and safer alternative to manual weld cap changes. 5-10 manual minute tip change cycles now take 20-30 seconds. Kyokutoh robotic tip dress units maintain the surface and dimensions of weld caps for longer life and consistent welds.
