Hello, my name is Chris Vanheule, and I am a Manufacturing Engineering student at Fanshawe College in London, ON Canada. For my english course in need to finish a technical report on Resistance Welding. One of the criteria of the report is a interview (internet is good enough) with a expert in the field. Could some one be so kind to help me.

All I am looking for is this question to be answered:

- What is the hardest part of resistance welding?

Thanks

Dear Chris, It is very difficult to pinpoint any specific part of resistance welding that is important.In my opinion all things involved are crucial to get a good weld quality in resistance welding.e.g. the machine itself, the electrode materials that are used, the quality of components,the setting parameters that are used.

Each of these factors will have a bearing on the final output.

Thanks and regards,

Dear Chris,

Can you be specific about what you mean by hardest ?

From Manufacturing engineering point of view, RW technology is preferred over other NON-PRESSURE WLEDING Techniques such as ARC Welding, CO2 Welding, etc., MAINLY Due to cater high PRODUCTION Requirement with relatively lesser OPERATOR SKILL.

Hope that the above could be of some help in your interview.

regards,

This is easy for me to answer, with my experience in automotive body- shop welding. By far, the hardest part is to convince those that manage the process of the need to commit resources to the resistance welding activity. It is always treated as a "necessary evil", with activities in robot programming, sealer application, controls and everything else having priority above resistance welding. Classically the Welding Engineer is given the responsibility of the process, without the authority to control it. My business is training and start-up assistance, and the tradesmen always are grateful for the information. The usual response is "why did it take 10 years to get you in here?" This indicates the lack of priority given to the process.

Dear Chris, The most difficult thing about resistance welding (and also the most rewarding), is gathering enough experience through your own efforts and by communicating with others in the field, so that when a new problem comes up you can say. 1) It can't be done. 2) It can be done, and this is how to do it. 3) If you make these changes, I can show you how to do it. Good luck. Regards, Tom Salzer
