Introduction to welding, pre-pressure, and hold time in medium-frequency inverter spot welding machines

Medium-frequency inverter spot welding machines ua hoʻohana nui ʻia i nā ʻoihana like ʻole no ko lākou hiki ke hana i nā welds ikaika a hilinaʻi. No ka hōʻoia ʻana i ka maikaʻi o ka weld a me ka hana, pono e hoʻomaopopo i nā manaʻo o ka welding, pre-pressure, a me ka manawa paʻa i kēia mau mīkini. Hāʻawi kēia ʻatikala i kahi hiʻohiʻona o ka wili, pre-pressure, a me ka manawa paʻa i nā mīkini wiliwili wahi inverter medium-frequency.

1. Welding: ʻO ka welding ke kaʻina hana mua e hoʻohui ʻia ai ʻelua mau ʻāpana metala me ka hoʻohana ʻana i ka wela a me ke kaomi. I loko o nā mīkini wiliwili wahi inverter medium-frequency, ʻo ke kaʻina hana hoʻoheheʻe e pili ana i ka hele ʻana i kahi au kiʻekiʻe ma o nā mea hana e hoʻohua i ka wela ma ka wahi pili. ʻO ka wela ka mea e heheʻe ai ka metala a hana i ka weld nugget, kahi e paʻa ai ke hoʻoluʻu. Hāʻawi ka weld nugget i ka ikaika a me ka pono o ka hui.
2. Pre-Pressure: Pre-pressure, i ʻike ʻia ʻo squeeze or electrode force, pili i ke kaomi mua i hoʻopili ʻia i nā mea hana ma mua o ka hoʻāla ʻia ʻana o ke au kuʻi. Pono ka pre-pressure no ka hōʻoia ʻana i ka pili pono ʻana a me ka alignment ma waena o nā mea hana a me nā electrodes. Kōkua ia i ka hoʻopau ʻana i nā āpau a i ʻole nā ​​kuhi hewa i hiki ke hoʻopilikia i ka maikaʻi o ka weld. Pono e lawa ka ikaika pre-pressure e hoʻokumu i kahi pilina paʻa me ka ʻole o ka hoʻololi ʻana a i ʻole ka pōʻino i nā mea hana.
3. Manawa Paʻa: ʻO ka manawa paʻa, ʻike ʻia ʻo ka manawa welding a i ʻole ka manawa nugget, ʻo ia ka lōʻihi o ka manawa e mālama ʻia ai ke au kuʻi ma hope o ka pae pre-pressure. ʻO ka manawa paʻa e hiki ai i ka wela ke puʻunaue like a maʻalahi i ka hoʻokumu ʻana i kahi weld nugget i kūkulu maikaʻi ʻia a ikaika. ʻO ka lōʻihi o ka manawa paʻa e pili ana i nā mea e like me ke ʻano mea hana, ka mānoanoa, ka wā welding, a me ka maikaʻi weld i makemake ʻia. He mea koʻikoʻi e hoʻoholo i ka manawa paʻa maikaʻi loa e hoʻokō i nā welds kūpaʻa a hilinaʻi.

ʻO ka welding, pre-pressure, a me ka manawa paʻa nā mea koʻikoʻi i ka hana ʻana o nā mīkini wiliwili wahi inverter medium-frequency. Pono ka hoʻomaopopo ʻana i nā loina ma hope o kēia mau kaʻina hana no ka hoʻokō ʻana i nā welds kiʻekiʻe me ka ikaika kūpono a me ka pololei. Ma ka hoʻonui ʻana i nā ʻāpana welding, me ka ikaika pre-pressure a me ka manawa paʻa, hiki i nā mea hana ke hōʻoia i nā welds hilinaʻi a kūpaʻa i nā noi like ʻole.
