WebJun 1, 2013 · Abstract and Figures. Shunting in resistance spot welding is difficult to avoid, as multiple welds are commonly designed in a specific area for strength and other … WebApr 1, 2016 · The shunting effect in multiple spot welds is influenced by a combination of effects due to both weld spacing and specimen temperature when other welding …
WebDescription. Since shunting always reduces the actual welding current, it should be avoided whenever possible. There are two primary sources of shunting: (1) Shunting due to existing spot welds, as shown in Fig. 1. (2) Shunting due to design, as shown in Fig. 2, where shunting inevitably occurs in series welding process. WebShunting. Refers to the deviation of the welding current from the weld to be made to a nearby weld or conductor during resistance welding. Post navigation. Previous Post …
WebBurn-Through. Burn-through occurs when the weld metal/filler material completely penetrates through the weld metal. This defect is of particular concern when welding materials less than ⅛ inch in thickness, roughly equivalent to 12-gauge. Prevent burn-through by controlling heat exposure in the weld. WebShunting effect of resistance spot welding is evaluated based on the electrode displacement signals. The shunted welds in mild steel with different weld spacing were produced. The results showed that the weld spacing and nugget diameter were polynomial-correlated, and the minimum welding spacing of 20 mm can be derived from the results.
WebShunting paths that can occur typically happen after the monitoring devices. For example, as the welding gun is clamping the work piece, other parts of the gun may make contact with other parts of the work piece causing current to divide itself. In the example above, the weld schedule calls out for 10,000 amperes however only 8,000 amperes goes ...

A reference-based adaptive resistance spot welding (RSW) method intended to reduce the shunting effect in short-pitch (≤40 mm) RSW is proposed in this … iphone x rayloWebAdditionally, carefully consider weld spacing. Placing spot welds too closely together can result in shunting. Here, some of the welding energy is lost through adjoining welds, possibly resulting in substandard weld strength. Spring-back of the parts being welded also can plague the RSW process. orange staff lanyardsWebFeb 1, 2024 · Shunting effect of resistance spot welding is evaluated based on the electrode displacement signals.

In such cases, previously made welds may affect the new weld and part of the current aimed for the new weld passes through the neighbouring welds. This effect is called shunting and is known to affect weld quality and reduce weld strength. A schematic of shunting is shown in Figure 1. orange stack cooker tupperware
