Pehea e koho ai i ka mea electrode o ka mīkini wiliwili wahi alapinepine?

Pehea e koho ai i ka mea electrode o ka mīkini wiliwili wahi alapinepine? Spot welding electrode poʻo ma o kēia manawa o nā tausani a hiki i nā ʻumi tausani o nā amperes, kū i ka volta o 9.81 ~ 49.1MPa, ka wela koke o 600 ℃ ~ 900 ℃. No laila, koi ʻia ka electrode e loaʻa i ka conductivity uila maikaʻi, conductivity thermal, thermal hardness and high corrosion resistance.

Hana ʻia nā electrodes wiliwili i nā ʻāpana keleawe. I mea e hoʻomaikaʻi ai i ka hana o nā electrodes alloy copper, pono e hoʻoikaika i ka mālama ʻana, e like me: ka hoʻoikaika ʻana i ke anuanu, ka hoʻoikaika ʻana i ka hopena paʻa, ka hoʻoikaika ʻana i ka ua a me ka hoʻopuehu ʻana. Hoʻololi hoʻi ka hana o ka electrode ma hope o nā ʻano hoʻoikaika like ʻole. I ka wā e pono ai e hoʻopili ʻia nā pā kila anu, nā pā kila galvanized, nā kila kila a i ʻole nā ​​​​papa alumini, pono e koho ʻia nā mea electrode kūpono e like me nā waiwai o nā mea pā.

ʻO ke koho ʻana i nā mea electrode no ka hoʻoheheʻe ʻana i ka pā kila galvanized e hōʻemi i ka ʻeleʻele a me ka deformation o ka electrode i ka wā o ka wili ʻana, kahi e koi ai i ka paʻakikī kiʻekiʻe, ka uila maikaʻi a me ka thermal conductivity o ka electrode ma ke kiʻekiʻe wela, a me ka liʻiliʻi alloying tendency me ka zinc.

ʻOi aku ka lōʻihi o ke ola electrode o ka hoʻoheheʻe ʻia ʻana o ka pā kila me kekahi mau mea electrode ma mua o ka electrode copper cadmium. No ka mea, ʻoiai ʻoi aku ka maikaʻi o ka uila a me ka thermal conductivity o ka cadmium copper, manaʻoʻiʻo ʻia ʻoi aku ka liʻiliʻi o ka adhesion o ka zinc, akā ʻoiaʻiʻo, ma muli o kona haʻahaʻa haʻahaʻa haʻahaʻa, ʻoi aku ka hopena o ka paʻakikī kiʻekiʻe. ʻOi aku ka kiʻekiʻe o ka paʻakikī o ka zirconium copper, no laila ʻoi aku ka lōʻihi o kona ola. ʻOiai ʻoi aku ka kiʻekiʻe o ka paʻakikī o ka beryllium daimana keleawe, no ka mea, ʻoi aku ka maikaʻi o kāna conductivity ma mua o ka chromium-zirconium keleawe, ʻo ka conductivity a me ka thermal conductivity ke kuleana nui i ka mana o kona ola, a ʻoi aku ka haʻahaʻa o kona ola electrode.

Eia kekahi, ʻo ka hoʻohana ʻana i ka tungsten (a i ʻole molybdenum) i hoʻokomo ʻia i ka electrode composite welding galvanized steel plate, ʻoi aku ka kiʻekiʻe o kona ola, ʻoiai ʻo ka conductivity o tungsten, molybdenum he haʻahaʻa, aia wale nō ma kahi o 1/3 o ke keleawe chromium, akā ʻoi aku kona wela wela. (1273K), paʻakikī kiʻekiʻe (ʻoi aku ka tungsten), ʻaʻole maʻalahi ka electrode i ka deformation.
