hot-formed steel<\/u><\/a>. The strength after convex welding can reach the point of tearing or pulling through the base material, with thrust strengths ranging from 8KN to 30KN.<\/p>\n![\"Post-welding](\"https:\/\/resistance-welding.com\/wp-content\/uploads\/2025\/12\/Post-welding-test-results-of-nuts.jpg\")
<\/p>\n
In exhaust systems, stainless steel convex nuts can have diameters exceeding \u00a230, requiring equipment power of up to 920KVA to meet welding demands. Another application scenario is the oil pan nuts, which require sealing; therefore, the equipment selected is often large energy storage welders.<\/p>\n
In the home appliance industry, the application of convex welding primarily focuses on water inlet welding, with convex diameters usually greater than \u00a220. The welding materials include stainless steel and low-carbon steel. Due to the relatively thin materials, the destructive testing after welding requires tearing through a ring of the base material to be considered qualified. Convex welding ensures both strength and effective sealing.<\/p>\n

Proceso de soldadura<\/h2>\n
Convex welding still falls under the category of projection welding and requires strict welding specifications, namely high current and high pressure. Compared to ordinary projection welding, the volume of convex welding is larger, resulting in a slightly longer required welding time, especially when using medium-frequency direct current welding, where welding times can reach 120-200 milliseconds. If using a capacitor discharge welder, the welding time does not need to be a major concern; instead, focus on selecting a larger welding current and pressure.<\/p>\n
In sealing-required scenarios, it is crucial to avoid large sparks during the welding process to prevent spatter from causing welding defects and leaks. This necessitates greater welding pressure and better responsiveness. The pressure spindle should use a diamond heavy-duty structure to ensure that no deformation or misalignment occurs under high pressure, thereby ensuring uniform melting around the convex area during welding.<\/p>\n
Conclusi\u00f3n<\/h2>\n
The welding of convex nuts plays a significant role across various industries, and the choice of welding technology and equipment directly impacts welding quality and product performance. Understanding the key factors and application scenarios of welding can help optimize welding processes and improve production efficiency.<\/p>","protected":false},"excerpt":{"rendered":"
