Talk:Electric resistance welding

resistance welding
the stimulation model was made by azim from india which is without convear belt in this i fixed a led which act as a material has to weld in this the led is glow for long time for iron and medium time for copper means the welding is done automatically and it adjust welding automatically according to the material. —Preceding unsigned comment added by 117.98.84.205 (talk) 04:20, 29 January 2008 (UTC)

The general the section on "spot welding" indicates several processes that are not in general considered resistance spot welds. For example, projection welding -- although a resistance welding process -- is not a "spot" weld, but a resistance projection weld. My experience is in the North American automotive industry (all of the "big 3") and as such we're generally in touch with AWS terminology. Although I don't have references handy, I would debate the application of the label "spot weld" to processes such as projection welding.

Principal of Welding
There is a weird incomplete sentence acting as a header under the introductory paragraph. The information it contains is poorly written and lacks references. I removed it. 68.179.88.89 (talk) 15:51, 15 March 2017 (UTC)

Merger proposal
Because these articles' scopes are almost perfect duplicates, I propose that the current Electric resistance welding article be merged into the Spot welding one, which is both older and more complete. I think that the content in the "Electric resistance welding" article can easily be inserted in the context of the "Spot welding" article, without any problems as far as article size or undue weight is concerned.

 * Oppose They're close, but they are distinct, and we should make this sort of decision on the basis of the scope for articles, not just their state at one particular time. Spot welding is an important topic, electric resistance welding an extremely broad one (even if not well reflected as yet). Andy Dingley (talk) 11:36, 11 October 2018 (UTC)
 * Weak oppose Spot welding is widely used (or at least was) for automobile and large appliance manufacture. Resistance welding, a superset of spot welding, is a rather diverse topic. I would think two articles would be more practical. Jim1138 (talk) 22:28, 11 October 2018 (UTC)
 * Support. The physics are the same, and there's not much in ERW (maybe 35% is about spot welding, and it doesn't build off spot welding for seam welding). Both Spot welding and ERW want to claim projection welding (which just has a better defined spot). Some seam welders are just a moving spot, and some seam welders are linear spot. Both articles point to other, more detailed, welding articles. I'm not seeing much meat in ERW. Merging them would give a better presentation. If the content about ERW gets better, the articles can be resplit later. Glrx (talk) 03:38, 13 October 2018 (UTC)
 * Comment. Not fussed either way, but the article would be titled Electric resistance welding, not Spot welding, which is a subset. As Andy Dingley says, look to the potential scope, not just what is there now. A merge will probably have to be split again some day, but until then it does not matter much. &middot; &middot; &middot; Peter Southwood (talk): 15:25, 7 October 2020 (UTC)
