Theoretical principles of resistance welding and process engineering

Resistance welding is based on the principle that an electric current flows through two workpieces under pressure, generating heat at the contact point which melts and joins the materials. The most common methods are:

1. roll seam welding
2. Spot welding
3. Projection welding

Selecting the right electrode:
The electrodes must ensure even heat distribution and be sufficiently durable. Copper alloys are ideal due to their high thermal conductivity. The shape and size of the electrodes influence the pressure and heat distribution during the welding process.

Parameter settings:
The correct parameter settings are crucial for a high-quality weld:

• Welding current
• Welding pressure
• Welding time
• Electrode force

To participate in the training, participants should have a basic understanding of the welding process. The training lasts one day , allowing for a compact yet in-depth exploration of the most important aspects of resistance welding.

This training course is aimed at welders and welding supervisors who already possess basic welding knowledge and wish to expand their skills in resistance welding. Participants should have a basic understanding of welding metal joints, as the course builds upon this foundation.

The aim of the training is to impart to participants the fundamental theoretical knowledge and practical skills in the field of resistance welding. Participants should not only understand the various welding processes, but also acquire the ability to apply these processes safely and competently. This includes both an understanding of the physical principles and the correct handling of the necessary machines and equipment.
